Check tic tac toe winner

I have a tic tac toe program. The board is stored in a two dimensional character array board[3][3]. Here is a function that is supposed to check if the player specified in the player argument wins. It doesn't work. Ideas?

Code:

---

bool is_threeinrow(char player, char board[3][3])
{
    bool done = 0;
    for (int x = 0; x < 3; x++)
    {
        if (board[x][0] == board[x][1] == board[x][2] == player)
        {
            return 1;
            done = 1;
        }
    }
    for (int y = 0; y < 3; y++)
    {
        if (board[0][y] == board[1][y] == board[2][y] == player)
        {
            return 1;
            done = 1;
        }
    }
    if (board[0][0] == board[1][1] == board[2][2] == player)
    {
        return 1;
        done = 1;
    }
    if (board[0][2] == board[1][1] == board[2][0] == player)
    {
        return 1;
        done = 1;
    }
    if (done == 0)
    {
    return 0;
    }
   
}

looks fine to me, beside the fact that done = 1 never gets set, but you don't need that anyway. In what cases is it returning the wrong result?

>> board[x][0] == board[x][1] == board[x][2] == player
You can't string together == like that because one call to == returns true or false, and so the character stored in the board will not be equal to the bool true or false the next time it is called.

Use a series of == expressions combined with &&.

doh! can't belive that I missed that.
