So I am writing a sudoku project, like I was in my previous post, I was able to save the written numbers, but the rewritten code is giving me issues, it's not saving the first number. I am pulling it from myGame.txt which includes the numbers 723400159600302008800010002070654020004207300050931040500070003400103006932000714, the first time through it reads the 7 but not the second or third when it's over written, I was wondering if you guys could offer some help. I couted sudoku[0][0] through the program and it goes from a 7 to a 0.
Here is my output of my couted index.
7>
Exp: >
E
> What are the coordinates of the square: B2
Here B2 has a 0 in it so it can be edited
> What is the value at 'B2': 9
>
> 0>
