As usual, the instructions for the next assignment are +in next-README. + +For this assignment, we have created compiled binaries (in +/usr/local/l2p/rot_matrix/ where rotateMatrix is correct, +and the numbered ones are each broken in some way). + +As with 09_testing2, you will write a file called tests.txt, +which will list the command line arguments you want to use to +run the programs. However, unlike 09_testing2, you will +also want to create a wide variety of input files. You can +name them anything you want, as long as you save them in the +current (26_tests_matrix_input) directory, and submit them +along with tests.txt. + +As usual, we have provided run_all.sh + +Hint 1: think about various error cases that the programmer +might have forgotten! + +Hint 2: The trickiest of these is one in which the programmer +did not pay attention to a rather subtle, but common mistake +pointed out in your reading titled 'Reading a File'! + +Hint 3: If you find yourself needing to create an input +file with non-typable/non-printable characters in it, +you will want to do a few things. + +First, (after you have the file you want to edit open), you +will want to force emacs to change the encoding it uses +(so that it won't try to rewrite things in Unicode, for example): + +M-x revert-buffer-with-coding-system +raw-text + +Once you have done this, you can do + +M-x hexl-mode + +to put emacs in hex editor mode. + +Then you will see hex values on the left, and their printable +interpreations (or . for non-printable characters) on the right. +Move the point to where you want to put a particular value, and do + +C-M-x + +then type the hex value (one byte, so two hex digits) that you want, +and hit enter. It will overwrite the current character with that value. +Then you can save the file. diff --git a/26_tests_matrix_input/grade.txt b/26_tests_matrix_input/grade.txt new file mode 100644 index 0000000..727e7c2 --- /dev/null +++ b/26_tests_matrix_input/grade.txt @@ -0,0 +1,20 @@ +Grading at Thu 02 Dec 2021 03:14:19 AM UTC +Checking rotateMatrix1 +Your tests identified the problem with rotateMatrix1 +Checking rotateMatrix2 +Your tests identified the problem with rotateMatrix2 +Checking rotateMatrix3 +Your tests identified the problem with rotateMatrix3 +Checking rotateMatrix4 +Your tests identified the problem with rotateMatrix4 +Checking rotateMatrix5 +Your tests identified the problem with rotateMatrix5 +Checking rotateMatrix6 +Your tests identified the problem with rotateMatrix6 +Checking rotateMatrix7 +Your tests identified the problem with rotateMatrix7 +Checking rotateMatrix8 +Your tests identified the problem with rotateMatrix8 +Your tests identified problems with all broken programs + +Overall Grade: PASSED diff --git a/26_tests_matrix_input/input.1 b/26_tests_matrix_input/input.1 new file mode 100644 index 0000000..104bde6 --- /dev/null +++ b/26_tests_matrix_input/input.1 @@ -0,0 +1,10 @@ +1234567890 +/n/n/n/n/n +%fdsfddgfg +afsafsjhgh +dgdgfgfgfg +addjfkga01 + fdsfdbvbd +ashfshflks +sajlasjfls +gjgjjhjhjj diff --git a/26_tests_matrix_input/input.10 b/26_tests_matrix_input/input.10 new file mode 100644 index 0000000..4a664e4 --- /dev/null +++ b/26_tests_matrix_input/input.10 @@ -0,0 +1 @@ +123456782345678 diff --git a/26_tests_matrix_input/next-README b/26_tests_matrix_input/next-README new file mode 100644 index 0000000..3484c1a --- /dev/null +++ b/26_tests_matrix_input/next-README @@ -0,0 +1,46 @@ +In a previous function, you write a function + + void rotate(char matrix[10][10]) + +which performed 90 degree clockwise rotation of a 10x10 +matrix.
