tic tac toe game

[Ross]

The game is suppose to let the player choose from whether play again or not. It seems my codes aren't working. Help me please.

#include <iostream>
#include <windows.h>
#include <cstdlib>
using namespace std;

char square[10] = {'o','1','2','3','4','5','6','7','8','9'};

int win();
void game();
void game()
{
system("cls");
cout << "\n\n\tTic Tac Toe\n\n";

cout << "Player 1 (X) - Player 2 (O)" << endl << endl;
cout << endl;

cout << "|'''''''|'''''''|'''''''|" << endl;
cout << "| " << square[1] << " | " << square[2] << " | " << square[3] << " |" << endl;

cout << "|_______|_______|_______|" << endl;
cout << "| | | |" << endl;

cout << "| " << square[4] << " | " << square[5] << " | " << square[6] << " |" << endl;

cout << "|_______|_______|_______|" << endl;
cout << "| | | |" << endl;

cout << "| " << square[7] << " | " << square[8] << " | " << square[9] << " |" << endl;

cout << "|_______|_______|_______|" << endl << endl;
}
