Hello Everyone
I am new to the forum,i have a simple code, everything works and goes fine. i just got stuck on a small detail.
The program is called tic tac toe. I just got stuck in the tie part. i just dont know where i can put an For or While statement to check once my square(board) is filled with the inputs by the players.

here is my code.

I once had trouble with this myself. You have this:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
 
if (winner == 'X')
{
    cout << "Strike! Player X's WON. Congrats!" << endl;
    break;
}
if (winner == 'O')
{
    cout << "Strike! Player O's Won. Congrats!" << endl;
    break;
}
else if (winner == 't')
{
    cout << "Tie! Program exiting..." << endl;
    break;
}

This is what had helped me was using something along these lines:
1
2
3
4
5
6
7
8
9
10
11
12
13

15
 
if (winner == 'X')
{
    cout << "Strike! Player X's WON. Congrats!" << endl;
    break;
}
else if (winner == 'O')
{
    cout << "Strike! Player O's Won. Congrats!" << endl;
    break;
}
else (winner == 't')
{
    cout << "Tie! Program exiting..." << endl;
    break;
}


Hope this helps. Good luck.
