        }
        printf("you entered a wrong sum.");
        player_move();
    }
    -----------------------------------------------------

    these are my problems:

    1. when i execute the program, why are the list of "sums" not sums? some are even difference! how can i fix this problem?

    2. this code is not yet complete. when the player inputs the sum of a box the letter in the box should be replaced with an 'X'. How can i do that?



    i badly need your help guys. thanks.

    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
