Sudoku Solver

This is a Sudoku Solver written in C.

I made this because I wanted to learn C. One of the objectives here, was to get no warnings when compiling the project.

Libraries:

The GUI version of this project requires gtk+3.0, but even if you don't have it on your machine, you can still use the command line version which will compile.

How to use this project:

Download and compile:

git clone https://github.com/execb5/Sudoku-Solver.git
cd Sudoku-Solver
make

This will generate two executables:

sudoku
sudokuGUI(see the lib section for dependencies)

sudokuGUI will open a graphical interface which I believe is self explanatory.

Command Line:

make sudoku will compile only the terminal version.

After compiling the project, all you have to do is run ./sudoku in the terminal, which will not work because you have to pass a sudoku file as parameter. The file should be in this format:

This is example 3 (examples/ex3)

0 0 0 2 0 0 0 6 3
3 0 0 0 0 5 4 0 1
0 0 1 0 0 3 9 8 0
0 0 0 0 0 0 0 9 0
0 0 0 5 3 8 0 0 0
0 3 0 0 0 0 0 0 0
0 2 6 3 0 0 5 0 0
5 0 3 7 0 0 0 0 8
4 7 0 0 0 1 0 0 0

Zeroes are blank cells on the board.

Running example 3:

$ ./sudoku examples/ex3
