Click my submissions to see the reason for your compile error.
don't use system("pause");

Try the I/O in this thread.

Thanks to every one who contributed their knowledge to this. I appreciate it

My 2 cents:
Make sure to skip unwanted input once you exit out of a for-loop early. So if you are reading in 9 values (each spot on the board), make sure to skip over the remaining values if you happen to exit the for-loop early.

The conditions I used:

Code: Select all

IF sum(wins) == 0:
    // check that either X == O or X - 1 == O
ELSE IF sum(wins) == 1:
    IF xwin == 1:
        // check that X - 1 == O
    ELSE: // owin == 1
        // check that X == O
ELSE
    // Cannot possibly come from tictactoe game

Finally I got AC using Python . But I suppose input data may have garbage in the last (e.g. additional space), so length for every row input is NOT 3...
