Tic tac toe

[Minimacfox]

Is it just me? Or is there ALOT of if statements in games like Tic tac toe? Or is there alot of if statements in most games?

example:

if
(marker_X == board[0][0] && marker_X == board[0][1] && marker_X == board[0][2] ||
marker_X == board[1][0] && marker_X == board[1][1] && marker_X == board[1][2] ||
marker_X == board[2][0] && marker_X == board[2][1] && marker_X == board[2][2] ||
marker_X == board[0][0] && marker_X == board[1][0] && marker_X == board[2][0] ||
marker_X == board[0][1] && marker_X == board[1][1] && marker_X == board[2][1] ||
marker_X == board[0][2] && marker_X == board[1][2] && marker_X == board[2][2] ||
marker_X == board[0][0] && marker_X == board[1][1] && marker_X == board[2][2] ||
marker_X == board[0][2] && marker_X == board[1][1] && marker_X == board[2][0])
                        {system("cls");
                         displayBoard(board);
                         cout << "\n           X WINS\n";
                         return 0;}
else if
(marker_O == board[0][0] && marker_O == board[0][1] && marker_O == board[0][2] ||
marker_O == board[1][0] && marker_O == board[1][1] && marker_O == board[1][2] ||
marker_O == board[2][0] && marker_O == board[2][1] && marker_O == board[2][2] ||
marker_O == board[0][0] && marker_O == board[1][0] && marker_O == board[2][0] ||
marker_O == board[0][1] && marker_O == board[1][1] && marker_O == board[2][1] ||
marker_O == board[0][2] && marker_O == board[1][2] && marker_O == board[2][2] ||
marker_O == board[0][0] && marker_O == board[1][1] && marker_O == board[2][2] ||
marker_O == board[0][2] && marker_O == board[1][1] && marker_O == board[2][0])
                        {system("cls");
                         displayBoard(board);
                         cout << "\n           O WINS\n";
                         return 0;}

There's usually not so much. You're just hardcoding all permutations... twice (once for X and once for O). You typically don't need to do that... in tic-tac-toe or in other games.

EDIT:

example:

//  assuming board[x][x] is either 'X' or 'O'


// see if there's a winner
char winner = 0;  // 0=no winner, 'X'=X is winner, etc

// see if there's a winner by column or row
for(int i = 0; i < 3; ++i)
{
    // check the rows
    if( (board[i][0] == board[i][1]) && (board[i][0] == board[i][2]) )   winner = board[i][0];
    
    // and columns
    if( (board[0][1] == board[1][i]) && (board[0][i] == board[2][i]) )   winner = board[0][i];
}

// check diagonal
if( (board[0][0] == board[1][1]) && (board[2][2] == board[1][1]) )  winner = board[1][1];
if( (board[0][2] == board[1][1]) && (board[2][0] == board[1][1]) )  winner = board[1][1];

// was there a winner?
if(winner != 0)
{
    cout << "\n      " << winner << WINS\n";
}

Disch! That's more ifs than the OP!
