simple tic tac toe

[chess2009]

Hi
I would like to write simple code for Tic-Tac toe that just checks the rows and columns and diagonals for X or O and for X if it matches , it returns 1 and for O returns 0 and otherwise return -1.(I have to define function called hasWon to do this)
How Can I do that ?

#include<iostream>
using namespace std;
int hasWon(char board[3][3]);
int main()
{
    int i,j;
	
	char board[3][3]={{'X','X','O'},
					  {' ','X','O'},
					  {' ','O','O'}};
	for(i=0; i<3; i++)
	{
		for(j=0; j<3; j++)
			cout<<board[i][j]<<"\t";
	cout<<endl;
	}
}

I could like just up to initialization of board and then what should I do to check rows and columns and diagonals.?
Any response will be highly appreciated.

I dont want to give you the solution but you can do that:
choose column - lets say 0 ,
For each index in column 0 (3 items) you check the row and column in the matrix.

You can check the diagonals at the end in a separate loop .
