C-sarSudoku is a program that can create a randomized sudoku grid with a unique solution. The program can also be passed an unsolved grid and finds a solution to the puzzle.
To compile, simply run make from the command line within the main directory.
Once compiled, run sudoku with
./sudoku modewhere mode is either going to be create or solve
To test, simply enter make test from the command line in the main directory.
This runs the testing.sh script that runs integration testing. The make test command then compiles and runs the sudoku-test file that uses macros to run test code written in sudoku.c. The outputs are saved to the testing.out file.
enter make clean into the command line within the C-sarSudoku/ directory to remove all object, executable, library, and core files that are created by the Makefile.
- 0: Ran correctly without errors
- 1: Incorrect number of arguments
- 2: Unable to allocate memory for grid array
- 3: Unexpected arg
- 4: Solve mode, no solutions to given grid
- 5: Solve mode, invalid user input
When inputting a grid into the solve mode, it is assumed that the grid is being passed in by alternating integer elements and whitespace characters.
-
Many of the functions assume that they are being poassed a grid with size 81, but the
process_inputfunction only reads in grids that are of size 81. It reads the first 81 if given more and returns an error if given fewer elements. -
There are checks in place that produce errors if non-integers are passed and the input is still read correctly if elements are separated by more than one whitespace character.
