Tic Tac Toe Trouble

[cher1201]

Hello! I am a beginner and I'm trying to learn the mechanism behind creating a tic tac toe board. I created this function, and it's not outputting information correctly. I want to learn how to do this using a two-dimensional array and nested loops. Can someone explain what I am doing wrong?

int board[3][3] = {{1,2,3},{4,5,6},{7,8,9}};

//function to display board
void printBoard(){
        int k = 0;
        for(int i=0; i < 3; i++){
                for(int j=0; j < 3; j++){
                        if ( i % 2 && j % 2 )
                                cout << board[i][j];
                        if ( i == 1 || i % 3 )
                                cout << '|';
                        if ( j == 1 || j % 3 )
                                cout << '_';
                }
                cout<<"\n";
        }
}
