This looks familiar. Look at the for loop setups:

        for(int box_height = i-1; box_height == i+1 ; box_height++)
        {
            for(int box_width = j-1; box_width == j+1 ; box_width++)

Do these for loops ever actually execute? Does a for loop run while or until the test is true?

  • The program executes normally but when i run check50 the results is all a zeros – Muhammed Jul 12 '20 at 20:38
