[jennwenn25]

Hello,
Been trying to work on this tic tac toe game and I can't seem to figure out how to post the moves to the board. Everything as I have it now seems ok with the compilier but I just need help with that part. Let me know . . thanks!!

I suggest that you create a new char array,initialize the array with 0i.e. '0', fill in the co-ordinates of the user's input, then display the array,using a for loop.

would this be anything close to what you need...?

void TicTacToe::postMove(int row, int col, char value)
{
     theboard[row][col] = value;
     showBoard();
}

void TicTacToe::postMove(int row, int col, char value)
{
     theboard[row][col] = value;
     showBoard();
}

Keep in mind that I am really new at this . . so it's confusing to me, lol . . this does not seem to work but I can see where you are going with this. I know that I need to -1 from the row and column because of the array. Like if the user enters 3 it would really be 2 in the array. I dont really know what to do to do that. Probably is something way more simple then I would think it would be.

then how about this..??

void TicTacToe::postMove(int row, int col, char value)
{
     theboard[row-1][col-1] = value; 
     showBoard();
}
