First, write the function + + rectangle canonicalize(rectangle r); + + which takes a rectangle, and "fixes" its representation + by ensuring that the width and height are non-negative (and + appropriately adjusting the x and/or y co-ordinate).

However, this time, you will test a slightly more complex program +with more broken implementations. + +You can find the correct implementation of the program at + +/usr/local/l2p/match5/correct-match5 + +This program determines who wins a very simple "card game". This "game" +is played with 5 "cards" per player and 2 players. A "card" in this +game is an ASCII character (so 'x' 'a' '!' '7' '$' etc are all valid cards). +Each player has exactly 5 cards, and the player with the most matching +cards wins. That is, 5 of a kind beats 4 of a kind, which bests 3 of a kind, +which beats a pair, which beats having no matching cards. If both +players have the same number of matching cards (e.g., both have 3 of a kind), +the hand is a tie. There are no tie breakers (so one player has +3 of a kind and the other has 3 of a kind + a pair, the pair does not matter). +The values of the cards don't matter (so three 'a's and three 'b's both tie). + +If you run the correct implementation, you can see the correct behavior: + +As some examples: + +$ /usr/local/l2p/match5/correct-match5 aaaaa bbbbb +Both hands tie: each has five of a kind + +$ /usr/local/l2p/match5/correct-match5 aaaaa bbbbc +Hand 1's five of a kind beats Hand 2's four of a kind + +$ /usr/local/l2p/match5/correct-match5 aaabb bbbbc +Hand 1's three of a kind loses to Hand 2's four of a kind + +If you look in /usr/local/l2p/match5, you will see that there are 296 broken +implementations. Note that you do NOT need to come up with 296 test cases---you +may have one test case which shows that several of these implementations +are broken. + +Furthermore, to help make this testing managable for you, we have provided +run_all.sh, which will read test cases from a file you create called tests.txt, +and run them against all broken implementations. In particular, each line +of tests.txt should be the command line arguments to one invocation of the +program under test. So if you wanted to test the program with the three +examples shown above, you would write the following in tests.txt + +aaaaa bbbbb +aaaaa bbbbc +aaabb bbbbc + +and then each broken program would be run three times, and have its behavior +compared to the correct implementation. If ANY test case in tests.txt identifies +a problem with a particular broken implementation, your test suite has +succeeded for that particular implementation. You need to develop +your test suite so that it identifies the problems with all broken implementations. + + +Lastly, I'll note that each of these broken implementations arises from +making small changes in the correct implementation which could represent +reasonable mistakes in programming (this is called "mutation testing" by +the way). None of these require finding +an obscure "magic bullet" input---they can all be found with a reasonble, +comprehensive test suite. + +You will submit tests.txt for this assignment. + diff --git

@@ +For this assignment, you will be practicing with the basics +of gdb. You will want to use gdb extensively during the rest +of the semester, as it is an incredibly useful tool to gather +information during the debugging process. For now, we +are just going to get started with some basic commands. +Be sure you have done the readings and watched +the video on gdb. + +Enclosed, you will find game.c and the compiled +binary game, for the most boring guessing game +ever. In the first round, the program thinks +of a secret number (it is the same every single time), +and asks you to guess it. You get exactly one try. +Note that it thinks of this number by calling +getSecretNumber, which is not included in the source. + +If you get that right, in the second round, +it thinks of another number. It does this by repeatedly +calling getOtherSN (also not shown in the source) and +passing in different numbers. It combines these results +together, and does some math to combine the results into +"total". Afterwards, it asks you for your guess, +and again, you have one chance. + +Before you proceed, try to "play" the game once by running: + +./game + + +For example, I ran it and guessed 4: +$ ./game +I'm thinking of a number... +What number do you guess? +4 +I'm sorry, that is not right. You lose + +It would be pretty boring to play this game +until you actually guess the right number and win, +but fortunately, that isn't the point. The +point is to practice with gdb. + +In emacs, do + +ESC-x gdb + +Emacs will prompt you for how to run gdb (the default should be fine), +and then give you the gdb prompt. +Use the "start" commmand to begin execution, then use "next" +and "print" to find the secret number for round 1. +When the program prompts you for this number, you should be able +to guess the right one from the information you gathered. + +For round 2, you do not want to step through 5000+ iterations of the +loop, so set a breakpoint after the loop, continue execution until you +reach it, and the print out the variable "total". Now you should +be able to win round 2 instantly as well! + +Once you have found the two secret numbers, create a file called input.txt +and place them in that file, one per line (round 1's secret number +on the first line, and round 2's on the second line). + +You should be able to run + +./game < input.txt + +and "win" automatically.

It will + tell you on what line of code valgrind detected the problem. Understand the + error, and why it is occuring (drawing some pictures will likely help here). + Fix the error, make, and re-run. Repeat the process until all valgrind errors are + gone. Don't forget that gdb may be useful as well. + + diff --git a/28_fix_vg_encr/encrypt.c b/28_fix_vg_encr/encrypt.c new file mode 100644 index 0000000..71b7156 --- /dev/null +++ b/28_fix_vg_encr/encrypt.c @@ -0,0 +1,60 @@ +#include <stdio.h> +#include <stdlib.h> +#include <ctype.h> +#include <string.h> + +void encrypt(FILE * f, int key, FILE * outfile){ + char * line=NULL; + size_t sz=0; + while (getline(&line,&sz, f) >= 0) { + char * ptr = line; + while (*ptr != '\0') { + int c = *ptr; + if (isalpha(c)) { + c = tolower(c); + c -= 'a'; + c += key; + c %= 26; + c += 'a'; + } + *ptr = c; + ptr++; + } + fprintf(outfile, "%s", line); + } + free(line); +} + +int main(int argc, char ** argv) { + if (argc != 3) { + fprintf(stderr,"Usage: encrypt key inputFileName\n"); + return EXIT_FAILURE; + } + int key = atoi(argv[1]); + if (key == 0) { + fprintf(stderr,"Invalid key (%s): must be a non-zero integer\n", argv[1]); + return EXIT_FAILURE; + } + FILE * f = fopen(argv[2], "r"); + if (f == NULL) { + perror("Could not open file"); + return EXIT_FAILURE; + } + //outfileNAme is argv[2] + ".txt", so add 4 to its length. + char * outFileName = malloc((strlen(argv[2]) + 5) * sizeof(*outFileName)); + strcpy(outFileName, argv[2]); + strcat(outFileName, ".enc"); + FILE * outFile = fopen(outFileName, "w"); + encrypt(f,key, outFile); + if (fclose(outFile) != 0) { + perror("Failed to close the input file!"); + return EXIT_FAILURE; + } + if (fclose(f) != 0) { + perror("Failed to close the input file!"); + return EXIT_FAILURE; + } + free(outFileName); + + return EXIT_SUCCESS; +} diff --git a/28_fix_vg_encr/grade.txt b/28_fix_vg_encr/grade.txt new file mode 100644 index 0000000..389f7f2 --- /dev/null +++ b/28_fix_vg_encr/grade.txt @@ -0,0 +1,28 @@ +Grading at Tue 14 Dec 2021 02:37:37 AM UTC +Attempting to compile encrypt.c +testcase1: +your output was correct + - Valgrind was clean (no errors, no memory leaks) +valgrind was clean +################################################# +testcase2: + - Valgrind was clean (no errors, no memory leaks) +valgrind was clean +################################################# +testcase3: + - Valgrind was clean (no errors, no memory leaks) +valgrind was clean +################################################# +testcase4: + - Valgrind was clean (no errors, no memory leaks) +valgrind was clean +################################################# +testcase5: + - Valgrind was clean (no errors, no memory leaks) +valgrind was clean +################################################# +testcase6: + - Valgrind was clean (no errors, no memory leaks) +valgrind was clean + +Overall Grade: A diff --git a/28_fix_vg_encr/input.txt b/28_fix_vg_encr/input.txt new file mode 100644 index 0000000..76a327a --- /dev/null +++ b/28_fix_vg_encr/input.txt @@ -0,0 +1,2 @@ +An example +Of the input. diff --git a/28_fix_vg_encr/input.txt.enc b/28_fix_vg_encr/input.txt.enc new file mode 100644 index 0000000..4d4e357 --- /dev/null +++ b/28_fix_vg_encr/input.txt.enc @@ -0,0 +1,2 @@ +hu lehtwsl +vm aol puwba. diff --git a/29_outname/Makefile b/29_outname/Makefile new file mode 100644 index 0000000..7cdf5f1 --- /dev/null +++ b/29_outname/Makefile @@ -0,0 +1,12 @@ +CFLAGS=-Wall -Werror -std=gnu99 -pedantic -ggdb3 +OBJS=outname.o outname_test.o +PROGRAM=outname_test + +$(PROGRAM): $(OBJS) + gcc $(CFLAGS) -o $@ $(OBJS) + +%.o: %.c outname.h + gcc -c $(CFLAGS) $< + +clean: + rm -f $(OBJS) $(PROGRAM) *~ diff --git a/29_outname/README b/29_outname/README new file mode 100644 index 0000000..735972e --- /dev/null +++ b/29_outname/README @@ -0,0 +1,18 @@ +In a future assignment, you are going to write a program which reads +some input, does some manipulations, and produces output in another file. +Right now, you are going to write a function which will be useful to you +in that assignment, which takes the input filename, and produces the output +file name.

The parameters specify the width + and height of the board, as well as the number of mines. + You will also need to call malloc (multiple times) + to allocate space for the 2D array "board". + This function should fill in all squares on the board with + UNKNOWN, then call addRandomMine an appropriate number of times + (i.e., numMines) to "randomly" place mines on the board. + Note that the fields of your board_t must be initailzed before + you call addRandomMine. + Also note that the mine generation is pseudo random and will not + change if you re-run the program multiple times with the same + parameters. + + Note that the layout of b->board should be such that it is indexed + b->board[y][x] + where y is between 0 and the height and x is between 0 and the width. + + - countMines: this funciton takes a board_t, and an (x,y) coordinate. + It should count the mines in the 8 squares around that (x,y) + coordinate, and return that count. Note that a mine may be + indicated by a square on the board either being HAS_MINE or + KNOWN_MINE. You can use the IS_MINE macro to test both cases: + IS_MINE(b->board[ny][nx]) + (where b is the board_t, and (nx,ny) are the coordinates you + want to check). Be careful not to go out of bounds of the array. + + - checkWin: this funciton takes a board_t and see if the game has + been won. The game is won when no squares are UNKNOWN. Return 0 + if the game has not been won, 1 if it has. + + - freeBoard: This function takes a board_t and frees all memory + associated with it (including the array inside of it). That is, + freeBoard should undo all the allocations made by a call to makeBoard. + +Note: You should NOT change any of the other provided functions! + + +Once you have these all working, you should have a playable game of +minesweeper. Note that there are a few differences in game play +from the "standard" game: + + - You select a square by entering its x (column) and y (row) coordinate. + The x coordinates are listed across the top and the y are listed + down the left side to reduce counting. + + - The game will automatically figure out the "obvious" squares: + both mines and non-mined spaces. It will reveal these too you + as soon as it considers them trivial to figure out. + + - You cannot manually mark a square that you suspect has a mine + +Once your code is complete, submit minesweeper.c diff --git a/31_minesweeper/grade.txt b/31_minesweeper/grade.txt new file mode 100644 index 0000000..b4cf79d --- /dev/null +++ b/31_minesweeper/grade.txt @@ -0,0 +1,24 @@ +Grading at Sun 19 Dec 2021 12:56:12 AM UTC +Attempting to compile minesweeper.c +################################################# +testcase1: +Your output is correct + - Valgrind was clean (no errors, no memory leaks) +valgrind was clean +################################################# +testcase2: +Your output is correct + - Valgrind was clean (no errors, no memory leaks) +valgrind was clean +################################################# +testcase3: +Your output is correct + - Valgrind was clean (no errors, no memory leaks) +valgrind was clean +################################################# +testcase4: +Your output is correct + - Valgrind was clean (no errors, no memory leaks) +valgrind was clean + +Overall Grade: A diff --git a/31_minesweeper/minesweeper.c b/31_minesweeper/minesweeper.c new file mode 100644 index 0000000..3ea9490 --- /dev/null +++ b/31_minesweeper/minesweeper.c @@ -0,0 +1,335 @@ +#include <stdio.h> +#include <stdlib.h> +#include <assert.h> +#include <limits.h> + +#define CLICK_KNOWN_MINE -2 +#define CLICK_INVALID -1 +#define CLICK_CONTINUE 0 +#define CLICK_LOSE 1 + +#define KNOWN_MINE -3 +#define HAS_MINE -2 +#define UNKNOWN -1 + +#define IS_MINE(x) ((x) == HAS_MINE || (x) == KNOWN_MINE) + + +struct _board_t { + int ** board; + int width; + int height; + int totalMines; +}; + +typedef struct _board_t board_t; + +void addRandomMine(board_t * b) { + int x; + int y; + //we could have a board too small for the number + //of mines that we request. try w*h*10 times before + //we give up + int limit = b->width * b->height * 10; + do { + x = random() % b->width; + y = random() % b->height; + assert(limit > 0); + limit--; + } while(b->board[y][x] == HAS_MINE); + b->board[y][x] = HAS_MINE; +} + +board_t * makeBoard(int w, int h, int numMines) { + board_t * b = malloc(sizeof(board_t)); + b->width = w; + b->height = h; + b->totalMines = numMines; + + b->board = malloc(h*sizeof(int *)); + for (int i = 0; i < h; i++) { + b->board[i] = malloc(w * sizeof(int)); + } + + for (int i = 0; i < h; i++) { + for (int j = 0; j < w; j++) { + b->board[i][j] = UNKNOWN; + } + } + + for (int i = 0; i < numMines; i++) { + addRandomMine(b); + } + return b; +} + +void printBoard(board_t * b) { + int found = 0; + printf(" "); + for (int x = 0; x < b->width; x++) { + printf("%d",x/10); + } + printf("\n "); + for (int x = 0; x < b->width; x++) { + printf("%d",x%10); + } + printf("\n----"); + for (int x = 0; x < b->width; x++) { + printf("-"); + } + printf("\n"); + for (int y = 0; y < b->height; y++) { + printf("%2d: ", y %100); + for (int x = 0; x < b->width; x++) { + if (b->board[y][x] == KNOWN_MINE) { + printf("*"); + found++; + } + else if (b->board[y][x] < 0) { + printf("?"); + } + else if (b->board[y][x] == 0) { + printf(" "); + } + else { + printf("%d", b->board[y][x]); + } + } + printf("\n"); + } + printf("\n----"); + for (int x = 0; x < b->width; x++) { + printf("-"); + } + printf("\n"); + + printf(" "); + for (int x = 0; x < b->width; x++) { + printf("%d",x/10); + } + printf("\n "); + for (int x = 0; x < b->width; x++) { + printf("%d",x%10); + } + printf("\nFound %d of %d mines\n", found, b->totalMines); +} +int countMines(board_t * b, int x, int y) { + int count = 0; + + for (int i = -1; i < 2; i++) { + for (int j = -1; j < 2; j++) { + if (x + i >=0 && x+i <= b->width-1) { + if (y + j >=0 && y+j <= b->height-1) { + if (IS_MINE(b->board[y+j][x+i])){ + count++; + } + } + } + } + } + return count; +} +int click (board_t * b, int x, int y) { + if (x < 0 || x >= b->width || + y < 0 || y >= b->height) { + return CLICK_INVALID; + } + if (b->board[y][x] == KNOWN_MINE) { + return CLICK_KNOWN_MINE; + } + if (b->board[y][x] == HAS_MINE) { + return CLICK_LOSE; + } + if (b->board[y][x] != UNKNOWN) { + return CLICK_CONTINUE; + } + + b->board[y][x] = countMines(b,x,y); + return CLICK_CONTINUE; +} + +int checkWin(board_t * b) { + for (int i = 0; i < b->width; i++) { + for (int j = 0; j < b->height; j++) { + if (b->board[j][i] == UNKNOWN) { + return 0; + } + } + } + return 1; +} + +void freeBoard(board_t * b) { + for (int i = 0; i < b->height; i++) { + free(b->board[i]); + } + free(b->board); + free(b); +} + +int readInt(char ** linep, size_t * lineszp) { + if (getline (linep, lineszp, stdin) == -1) { + fprintf (stderr,"End of file from keyboard reading a number.

This enum also has NUM_SUITS, +which will have a numeric value of 4 (indicating +how many suits there are), and can also +be used to indicate an invalid suit. + +Next, you will see a struct for a card. +This struct has two parts, a value +(2,3,4,5,6,7,8,9,10,J,Q,K,A) and a suit (s,h,d,c). +Following the struct declaration, there +are some #defines for constants for +the values of Ace, King, Queen, and Jack. +Accordingly, a card's value should +be between 2 and 14 (inclusive). + +There is also an enum for the hand +ranking (what kind of poker hand you get). +We won't be doing anything with these +at this point, except for writing a function +to convert from the enumerated values +to a string. + +Last are some function prototypes. +You will write each of these in cards.c. + +Now go into cards.c, and write each of these +functions. Here are the specifics: + +- void assert_card_valid(card_t c); + This function should use assert() to check + that the card passed in has valid values. + In particular, its value should be between + 2 and VALUE_ACE (inclusive of both), + and its suit should be between SPADES + and CLUBS (inclusive of both). + +- const char * ranking_to_string(hand_ranking_t r); + This function should convert the + hand_ranking_t enumerated value passed + in to a string that describes it. Remember + that Drew showed you a nice way to do this + with emacs keyboard macros! + +- char value_letter(card_t c); + This function should return the character that textually represents + the value of the passed-in card. For values 2-9, this should + be that digit. For 10, it should be '0', and for Jack, Queen, King, and Ace, + it should be 'J', 'Q', 'K', and 'A' respectively. + Hint: remember everything is a number. + For example, the character '0' has the decimal value 48, + and the character '5' has the decimal value 53, so you could represent + '5' as '0' + 5. + +- char suit_letter(card_t c); + This function should return the letter that textually represents + the suit of the card passed in ('s', 'h', 'd', or 'c' for SPADES, + HEARTS, DIAMONDS, or CLUBS). + +- void print_card(card_t c); + This function should print out the textual + representation of the card (hint: use the functions + you previously wrote). It should print + the value first, then the suit. For example, + As (for Ace of spades) + 0d (for 10 of diamonds) + Kc (for King of clubs) etc. + This function should not print any additional + spaces or newlines after the card's text. + +- card_t card_from_letters(char value_let, char suit_let); + This function should make and return a + card_t whose value and suit correspond + to the letters passed in. If the values passed + in are invalid, you should use assert() + or print an error message and exit(EXIT_FAILURE). + +- card_t card_from_num(unsigned c); + This function should take a number from 0 (inclusive) + to 52 (exclusive) and map it uniquely to + a card value/suit combination. Exactly + how you map the numbers to values/suits + is up to you, but you must guarantee + that each valid value/suit combination + corresponds to exactly one input value + in the range [0,52). Hint: you may want to use the mod + operator % to find the remainder of a number divided by 13. + (In Course 3, this function will be used + to make a deck of cards by iterating + over that range and calling it once + for each value--you just need + to learn about arrays first so you + have a place to put all those + cards.) + +---------------------------------------------------- +Once you have done all of these (and tested +them to your satisfaction with my-test-main.c), +you can + +make poker + +and try out the poker odds computation. It +requires one command line argument--the input file to read. +In the input file, +each line corresponds to one hand and lists +the cards (with textual representation +you were working with above). It also +has placeholders for future cards, which +are a ? followed by a number. For example, +this input: + +As Ah Kc Qd 6c ?0 ?1 +2c 3d Kc Qd 6c ?0 ?1 +Ks Qs Kc Qd 6c ?0 ?1 + +describes 3 hands (as might occur +in a game of Texas Hold'em). All +three hands share the King of clubs, +the Queen of diamonds, and the 6 +of clubs (called the "flop" +in Texas Hold'em--these are the +3rd, 4th, and 5th cards). Each +hand has its own private cards +to start (the first has the +Ace of Spades and the Ace of Hearts, +for example). + +The remainder of the hand will be +played by dealing two more cards +(?0 and ?1), which will be shared +by the three hands. + +You could also craft an input +where each player's cards are private +(no cards shared), such as this: + +As Kh ?0 ?1 ?2 +Ac Kc ?3 ?4 ?5 +Ad Ah ?6 ?7 ?8 + +9 cards remain in the future (?0 +through ?8), each appearing exactly +once in one hand. diff --git a/c2prj1_cards/cards.c b/c2prj1_cards/cards.c new file mode 100644 index 0000000..c335826 --- /dev/null +++ b/c2prj1_cards/cards.c @@ -0,0 +1,131 @@ +#include <stdio.h> +#include <assert.h> +#include <stdlib.h> +#include "cards.h" + + +void assert_card_valid(card_t c) { + assert(c.value >= 2 && c.value <= VALUE_ACE);

Check if a straight starts at position i" + In such an algorithm, [something] could be off by one) + + - Think about ways in which a programmer might mis-think about what + they need to do. For example, one might think you can check for a + straight flush by checking for a straight AND a flush, but that is + not correct (with more than 5 cards, you could have some that are a + straight but others of the same suit). + + - Be sure to just provide simple coverage of the basic cases (each + type of hand outcome, etc). + + - The suits are numbers, and can be iterated across )where do you + think we iterate over all the suits?). What if we counted wrong + when iterating over the suits? + + + - Two pairs have some subtle cases in terms of selecting the right 5 + cards for the final hand. Remember from the reading that the way + tie breaking works requires the final 5 card hand to be ordered: + (larger pair) (smaller pair) (tiebreaker) + + - Think about everywhere the programer could be off-by-one. + This might include such things as counting through all the + positions in the hand (either missing the start or the end), + or being off-by-one in how many cards are required + for a particular hand (e.g., only requiring 4 + cards meet a particular condition instead of 5). + + - Note that you may be able to 'game' your way into passing all + the tests locally, but if you do this you won't actually pass the + assignment.

This means that if you have OTHER pointers +(as you will have in Course 4 to handle unknown cards), +they will still point to the right place. + +For example, if you have (Ah,Ks,Qc,?0): + + Ah Ks Qc ?0<----to_replace + ^ ^ ^ ^ + | | | | + | | | | + | | | | + +--|--+--|--+--|--+--|--+ +arr->| | | | | | | | | + +-----+-----+-----+-----+ + +and you shuffle the pointers in the array +(yielding, e.g, Ks, ?0, Ah, Qc) : + + /------\ + V \ + Ah Ks | Qc ?0<----to_replace + ^ | ^ ^ + ____/ \ \ / + / ___\___\___/ + / / \ --- + +--|--+--|--+--\--+--\--+ +arr->| | | | | | | | | + +-----+-----+-----+-----+ + +the to_replace pointer still points at ?0 +with no other changes. If we had an array +of cards and shuffled them directly, it would +be much harder to do the card replacement later. + + +First, you will write four functions in deck.c: + + - void print_hand(deck_t * hand); + This should print out the contents of a hand. + It should print each card (recall that + you wrote print_card in Course 2), and + a space after each card. Do not put + a newline after the hand, as this + function gets called to print a hand + in the middle of a line of output. + + + - int deck_contains(deck_t * d, card_t c); + This function should check if a deck + contains a particular card or not. If + the deck does contain the card, this + function should return 1. Otherwise, + it should return 0. + (You will use this later to + build the deck of remaining cards + which are not in any player's hand). + + - void shuffle(deck_t * d); + This function takes in a deck an shuffles + it, randomly permuting the order of the cards. + There are MANY valid ways to shuffle a deck + of cards---we'll leave the specifics + of the algorithm design up to you. However, + you will want to use random() to generate + pseudo-random numbers. (Pseudo-random + numbers are quite sufficient here, + since they are not used for security + purposes). Note that you should not need to + use the 'srand' function. + + We will note that in trying to devise + this algorithm, you should not + try to shuffle a deck of cards "normally". + Instead, you should take a small number + of cards, and think about ways + to shuffle them that involve using + random numbers to swap their order, + or pick positions for them, or + similar principles. + +- void assert_full_deck(deck_t * d); + This function should check that + the passed in deck contains ever + valid card exactly once. If + the deck has any problems, this function + should fail an assert. This will + be used to help you test your deck + shuffling: we will shuffle + a full deck, then call assert_full_deck, + so that you can identfiy problems with + the deck. You can print + any error messages you want + if there is a problem. + Hint: you already wrote deck_contains. + +------------ +Once you have completed these functions, you should run + +make test-deck + +This will build the test-deck program which we +have provided which runs some test cases on your functions. +There is no one single right output, as you may shuffle +your deck any way that you want. However, you should +read through the output and see if things make sense. +The first deck is built by using your card_from_num +function (from Course 2) for each value in the +range [0,52). Then the deck is shuffled +a couple times, with the results printed. +We call assert_full_deck on each of these. + +Next we make a 5 card hand, and test +deck_contains on it, shuffle, and repeat +the process a few times. + +The last thing we do is take the 5 card +hand and shuffle it 50,000,000 (50 Million) +times, counting how often each hand occurs. +In an ideal case, each of the 120 possible +5-card hands would appear equally often (0.833% +of the time). If your shuffle is close +to this, then it is good. If it is drastically +off, that is bad. + +Since this can take a while, the test +program will print a '.' ever 500,000 +shuffles to let you know it isn't stuck. + +When it finishes, it will print out the +frequency (and ordering) of the most and least +common hands. For my shuffling algorithm, +these were 0.836496% and 0.829262% respectively, +which is quite good. If you end up with +things in the 0.823% (min) to 0.843% (max) range, that's +great. If its in the 0.818%(min) to 0.848% (max) range, +that's good enough. If you are outside of that, you +should try to work on your shuffling algorithm +to make sure you get good results from your poker +simulator. + +We provide that hands that appear most and least +often in case it helps you debug. + +Once you are satsified with the functionality +of your code for this part, run grade. +When you pass, you get the hand evaluation in +the next part. + diff --git a/c3prj1_deck/cards.c b/c3prj1_deck/cards.c new file mode 120000 index 0000000..1b5fce4 --- /dev/null +++ b/c3prj1_deck/cards.c @@ -0,0 +1 @@ +../c2prj1_cards/cards.c

It's also not super interesting: + it mostly make a bunch of calls to the functions + you wrote above, and has a lot of if-statements + to handle the rules of poker. + + The important part of evaluate_hand is that + (a) assumes the cards in the passed in hand are + sorted and (b) it returns a hand_eval_t for the passed in hand. + + That means that to implement compare_hands, you should + + (a) sort each hand using qsort on the hand's cards + and your card_ptr_comp [from earlier] + (b) Call evaluate_hand on each hand, which gives you a hand_eval_t + for each hand. + (c) Check if the rankings in the hand_eval_t are the same + or different. If they are different, you can just use + the ranking to determine the winner. + (d) If they are the same, then you need to look + at the values in the cards array of each hand_eval_t + to break the tie. The way that we constructed + the hand_eval_t's cards array means that + the cards are already ordered from most significant (at index 0) + to least significant (at index 4). You can just + do a lexicographic comparison on the values in the arrays. + (Its like comparing strings, but you are comparing values + of cards---if element 0 is the different, use that difference + to determine your answer. If element 0 is the same, + look at element 1, and so on). +Note that compare hands should return a positive number +if hand 1 is better, 0 if the hands tie, and a negative number +if hand 2 is better. + +You will also notice some functions at the bottom of eval.c that +we provided.

This makes it much easier to find straights (cards + in order), and you will have "N of a kind"s grouped together. +(2) The code to find "N of a kind" is basically the same + for 4, 3, and 2 (so we can abstract it out into a function...) +(3) Full house and two pair are just three of a kind and a pair + (so we already have that code...) with another pair + (so we can just write a function to find a secondary pair) +(4) We are going to make two simplifying assumptions: + - if there is a flush, it will occur in at most one suit. + (i.e., you won't have As Ah Kh Qs 8s 7h 4s 3s 3h 2h, + which has two different flushes). + - if there is an ace-high straight, there is not also + an ace-low straight. + (These both hold for all major poker variants) + +If you open up eval.c, you will find the following functions +that you will need to write: + + - int card_ptr_comp(const void * vp1, const void * vp2) + You want to sort the hand by value, so you need + a comparison function to pass to quicksort. + Quicksort sorts into ascending order, but you + want descending order, so you will want to + return + something < 0 if card1 > card2 + 0 if card1 == card2 + something > 0 if card1 < card2 + If two cards have the same value, compare them by + suit in the same order as the enum suit_t: + club < diamond < heart < spade + Note that vp1 and vp2 are passed as const void * + because that is the type that qsort demands. + They will should each be assigned to variables + of type + const card_t * const * cp1 + before using them (this is much like sorting + an array of strings from your readings). + To learn more about using the C library function qsort, + we suggest reviewing the course reading + "Sorting Functions" in the "Function Pointers" + lesson and consulting "man qsort" + to read about the comparison function. + + - suit_t flush_suit(deck_t * hand); + This function looks at the hand and determines + if a flush (at least 5 cards of one suit) exists. + If so, it returns the suit of the cards comprising + the flush. If not, it returns NUM_SUITS. + For example: + Given Ks Qs 0s 9h 8s 7s, it would return SPADES. + Given Kd Qd 0s 9h 8c 7c, it would return NUM_SUITS. + + - unsigned get_largest_element(unsigned * arr, size_t n); + This function returns the largest element in an array + of unsigned integers. This should be familiar + from the videos you watched. + + In course 4 (after you learn to dynamically allocate + memory), you will write get_match_counts, + which will construct an array with one element + per card in the hand. That array will + tell you how many cards in the hand + have the same value as the corresponding + card. You will then use get_largest_element + to figure out which is the best "N of a kind". + + + - size_t get_match_index(unsigned * match_counts, size_t n,unsigned n_of_akind); + This function returns the index in the array (match_counts) whose + value is n_of_akind. The array has n elements. The array match_counts + may have multiple values equal to n_of_akind. You should return + the LOWEST index whose value is n_of_akind [which also guarantees + it corresponds to the largest valued cards, since they will be sorted]. + (Once you figure out the best n_of_akind above, + you will use this to locate that group of cards + in the hand). + Note that it is guaranteed that n_of_akind is in match_counts. + If not, you should abort as this is evidence of an error. + + + - size_t find_secondary_pair(deck_t * hand, + unsigned * match_counts, + size_t match_idx) ; + When you have a hand with 3 of a kind or a pair, + you will want to look and see if there is another + pair to make the hand into a full house or + or two pairs. This function takes in + the hand, the match counts from before, and + the index where the original match (3 of a kind + or pair) was found. It should find + the index of a card meeting the following conditions: + - Its match count is > 1 [so there is at least a pair of them] + - The card's value is not the same as the value of the + card at match_idx (so it is not part of the original + three of a kind/pair) + - It is the lowest index meeting the first two conditions + (which will be the start of that pair, and the highest + value pair other than the original match). + If no such index can be found, this function should + return -1. + + - int is_straight_at(deck_t * hand, size_t index, suit_t fs) + This function should determine if there is a straight + starting at index (and only starting at index) in the + given hand. If fs is NUM_SUITS, then it should look + for any straight. If fs is some other value, then + it should look for a straight flush in the specified suit. + This function should return: + -1 if an Ace-low straight was found at that index (and that index is the Ace) + 0 if no straight was found at that index + 1 if any other straight was found at that index + + When writing this function, you can assume + that the hand is sorted by value: the + values of cards will appear in descending order. + (A K Q ... 4 3 2). + + There are two things that make this function + tricky (probably the trickiest function in + this assignment): + (1) Ace low straights. An Ace low straight + will appear in the hand with the Ace + first, then possibly some other cards, + then the 5 4 3 2. For example, you + might have + As Ks Qc 5s 4c 3d 2c + (2) You may have multiple cards with the + same value, but still have a straight: + As Ac Ks Kc Qh Jh 0d + has a straight even though A K Q + do not appear next to each other in + our sorted order. + Hint: I made this easier on myself, by writing + two helper functions: + int is_n_length_straight_at(deck_t * hand, size_t index, suit_t fs, int n) ; + and + int is_ace_low_straight_at(deck_t * hand, size_t index, suit_t fs); + + The second of these lets me pull out the complexities of an ace + low straight. However, in doing so, I realized that there + would be a lot of duplication of code between the ace low straight + helper and the original function (for an ace low, you want to find + a 5, then a straight of length 4: 5, 4, 3, 2). This realization + caused me to pull out much of the code into is_n_length_straight_at, + so that I could call it with n=4 to search for the 5,4,3,2 part + of an ace low straight. + + + - hand_eval_t build_hand_from_match(deck_t * hand, + unsigned n, + hand_ranking_t what, + size_t idx) ; + Now you have written a bunch of functions that + will figure out which ranking a hand has. It + is time to construct a hand_eval_t (see eval.h) which + has the ranking and the 5 cards used for it. + This helper function will handle the + "n of a kind" case. + It should make hand_eval_t and set its + ranking to the passed in "what" value. + Then it should copy "n" cards from + the hand, starting at "idx" into + the first "n" elements of the hand_eval_t's + "cards" array. The cards field in + hand_eval_t is declared as: + card_t * cards[5] + This is an array of pointers, each to a card_t. + Draw a picture to be sure you know how to name + each card_t "box" before you start writing code. + + Your function should then fill the remainder + of the "cards" array with the highest-value + cards from the hand which were not in + the "n of a kind". + + For example, given this hand: + As Kc Kh Kd Qc 8s 5d + The hand has 3 kings, and the As and Qc will break ties. + Note that here n = 3, what= THREE_OF_A_KIND, idx= 1. + So the cards array in the hand_eval_t should have + + Kc Kh Kd As Qc + + Note that what may also be FULL_HOUSE or TWO_PAIR, + since this function will get used for the first + part of preparing those evaluations (then other code + will later fix the rest of the hand with the other pair). + + + - int compare_hands(deck_t * hand1, deck_t * hand2) + + This is the goal of the whole thing: given two hands, + figure out which wins (or if it is a tie). + Everything you wrote goes together to make this work! + + + We're providing you with + hand_eval_t evaluate_hand(deck_t * hand) ; + since it involves some things you won't learn until + Course 4. It's also not super interesting: + it mostly make a bunch of calls to the functions + you wrote above, and has a lot of if-statements + to handle the rules of poker. + + The important part of evaluate_hand is that + (a) assumes the cards in the passed in hand are + sorted and (b) it returns a hand_eval_t for the passed in hand. + + That means that to implement compare_hands, you should + + (a) sort each hand using qsort on the hand's cards + and your card_ptr_comp [from earlier] + (b) Call evaluate_hand on each hand, which gives you a hand_eval_t + for each hand. + (c) Check if the rankings in the hand_eval_t are the same + or different. If they are different, you can just use + the ranking to determine the winner. + (d) If they are the same, then you need to look + at the values in the cards array of each hand_eval_t + to break the tie. The way that we constructed + the hand_eval_t's cards array means that + the cards are already ordered from most significant (at index 0) + to least significant (at index 4). You can just + do a lexicographic comparison on the values in the arrays. + (Its like comparing strings, but you are comparing values + of cards---if element 0 is the different, use that difference + to determine your answer. If element 0 is the same, + look at element 1, and so on). +Note that compare hands should return a positive number +if hand 1 is better, 0 if the hands tie, and a negative number +if hand 2 is better. + +You will also notice some functions at the bottom of eval.c that +we provided. You don't need to do anything to these---we wrote +them for you to keep the amount of code manageable. + +-------------- +That sure was a lot of code! You've been compiling and testing +along the way, right? We sure hope so :) + +However, to help you test things out even more, we've +provided some test infrastructure for you. + +If you do + +make + +You will compile the test-eval program you are +familiar with from Course 2. This program behaves +exactly like it did in Course 2. As a reminder, +it expects input where each line looks like: + +hand1 ; hand2 + +where a hand looks like something that print_hand +would output. So a valid input might be + +Kc Ac Jh 8s 9c 2s ; Ah Kh 0s 7c 7h 3c + +For each line in the input, the test program +will tell you: + - The results of your functions that went into evaluating it + (if there was a straight, if there was a flush, etc). + - What hand_eval_t was returned by evaluate_hand for each hand + - Which hand won (or if it was a tie) according to compare_hands + +Good thing you have all those test cases from Course 2 +to use with it! + +Because you have an object file test-eval.o and not the source +test-eval.c, you may need to use the debugger differently than you're +used to. For this test program, we recommend running gdb in emacs, +then first, specifying the command line argument (in this case, a file +name with your tests) + +set args tests.txt + +Then you will want to set a breakpoint in the code you wrote (since +you can't see test-eval.c, where main is, to step through it). For +example, if you just wrote the function is_straight_at, and it doesn't +behave the way you expect, you can do + +break is_straight_at + +and gdb will pause execution any time the program calls that +function. Then you can use the command "run" instead of "start," since +you don't need to pause execution at the start of main. Also recall +the command "continue," which you can review from the debugging +lesson. + + +As usual, when you are finished, use the "grade" command. +When you pass, this, congratulations! You are done +with Course 3 and ready to move on to Course 4 :) + + + + diff --git a/c3prj2_eval/cards.c b/c3prj2_eval/cards.c new file mode 100644 index 0000000..8e467ec --- /dev/null +++ b/c3prj2_eval/cards.c @@ -0,0 +1,131 @@ +#include <stdio.h> +#include <assert.h> +#include <stdlib.h> +#include "cards.h" + + +void assert_card_valid(card_t c) { + assert(c.value >= 2 && c.value <= VALUE_ACE);

In this assignment, +you will do (1) above. In the next assignment, you will do (2) and (3), +which will work together to process the input. In the final assignment, +you will do (4), completing this project! + + +Finish deck/evaluation +---------------------- +Add these functions to deck.c: + - void add_card_to(deck_t * deck, card_t c); + Add the particular card to the given deck (which will + involve reallocing the array of cards in that deck). + - card_t * add_empty_card(deck_t * deck); + Add a card whose value and suit are both 0, and return a pointer + to it in the deck. + This will add an invalid card to use as a placeholder + for an unknown card. + - deck_t * make_deck_exclude(deck_t * excluded_cards); + Create a deck that is full EXCEPT for all the cards + that appear in excluded_cards. For example, + if excluded_cards has Kh and Qs, you would create + a deck with 50 cards---all of them except Kh and Qs. + You will need to use malloc to allocate this deck. + (You will want this for the next function). + Don't forget you wrote card_t card_from_num(unsigned c) + in Course 2 and int deck_contains(deck_t * d, card_t c) + in Course 3! They might be useful here. + - deck_t * build_remaining_deck(deck_t ** hands, size_t n_hands) ; + This function takes an array of hands (remember + that we use deck_t to represent a hand). It then builds + the deck of cards that remain after those cards have + been removed from a full deck. For example, if we have + two hands: + Kh Qs ?0 ?1 ?2 ?3 ?4 + As Ac ?0 ?1 ?2 ?3 ?4 + then this function should build a deck with 48 + cards (all but As Ac Kh Qs). You can just build + one deck with all the cards from all the hands + (remember you just wrote add_card_to), + and then pass it to make_deck_exclude. + - void free_deck(deck_t * deck) ; + Free the memory allocated to a deck of cards. + For example, if you do + deck_t * d = make_excluded_deck(something); + free_deck(d); + it should free all the memory allocated by make_excluded_deck. + Once you have written it, add calls to free_deck anywhere you + need to to avoid memory leaks. + +Next, go back to eval.c, and implement: + - unsigned * get_match_counts(deck_t * hand) ; + You will find its prototype after the code you wrote + in Course 3, and before the functions we + provided for you. Replace the prototype with + your implementation. + + Given a hand (deck_t) of cards, this function + allocates an array of unsigned ints with as + many elements as there are cards in the hand. + It then fills in this array with + the "match counts" of the corresponding cards. + That is, for each card in the original hand, + the value in the match count array + is how many times a card of the same + value appears in the hand. For example, + given + Ks Kh Qs Qh 0s 9d 9c 9h + This function would return + 2 2 2 2 1 3 3 3 + because there are 2 kings, 2 queens, + 1 ten, and 3 nines. + +We recommend you write your own testing code in a separate +C file (e.g., test-c4deck.c) and run your own test cases +before you submit. When you are satisfied with the correctness +of your code, you should grade this assignment. + +As a final note, we remind you that since previously released files +have been symlinked into other directories you may need to add the +original versions (as this is where your changes are reflected). For +example, in this assignment we have you modify deck.c which is symlinked +to ../c3prj1_deck/deck.c. This means when you submit the assignment you +need to add and commit the actual file, not the symlink itself. diff --git a/c4prj1_deck/cards.c b/c4prj1_deck/cards.c new file mode 120000 index 0000000..1b5fce4 --- /dev/null +++ b/c4prj1_deck/cards.c @@ -0,0 +1 @@ +../c2prj1_cards/cards.c
