A grid maker for grid based games.
Change the num_of_rows and num_of_cols variables to the desired number, and then run the program.
The default grid layout consists of all zeroes (0). Press 0-9 to select what number should be placed in the grid. 0 is blank, which basically makes it an eraser.
Press enter or close the window when done drawing. The grid will then be printed to the terminal.
