Question

I\'m creating a TicTacToe class that contains a 3 by 3 rectangular array of integers & is played by 2 human players. \"1\" is used for the first player\'s move & \"2\" i

Answer 1

As Iiya has said, you're going to have to through through all the win cases. There's many ways to do that but the very gist of it in code would be

private bool checkWinner(int player)
{
    // check rows
    if (board[0, 0] == player && board[0, 1] == player && board[0, 2] == player) { return true; }
    if (board[1, 0] == player && board[1, 1] == player && board[1, 2] == player) { return true; }
    if (board[2, 0] == player && board[2, 1] == player && board[2, 2] == player) { return true; }

    // check columns
    if (board[0, 0] == player && board[1, 0] == player && board[2, 0] == player) { return true; }
    if (board[0, 1] == player && board[1, 1] == player && board[2, 1] == player) { return true; }
    if (board[0, 2] == player && board[1, 2] == player && board[2, 2] == player) { return true; }

    // check diags
    if (board[0, 0] == player && board[1, 1] == player && board[2, 2] == player) { return true; }
    if (board[0, 2] == player && board[1, 1] == player && board[2, 0] == player) { return true; }

    return false;
}

You can optimise this however which way you'd like (using for loops or matrices). Note the checkWinner() function requires a player input.
