Code:

#include <iostream>
using namespace std;

char square[10] = { 'o','1','2','3','4','5','6','7','8','9' };
int checkwin();
void board();

int main()
{
       int player = 1, i, choice;
       char mark;
       do
       {
              board();
              player = (player % 2) ? 1 : 2;
              cout << "Player " << player << ", enter a number:  ";
              cin >> choice;
              mark = (player == 1) ? 'X' : 'O';
              if (choice == 1 && square[1] == '1')
                     square[1] = mark;
              else if (choice == 2 && square[2] == '2')
                     square[2] = mark;
              else if (choice == 3 && square[3] == '3')
                     square[3] = mark;
              else if (choice == 4 && square[4] == '4')
                     square[4] = mark;
              else if (choice == 5 && square[5] == '5')
                     square[5] = mark;
              else if (choice == 6 && square[6] == '6')
                     square[6] = mark;
              else if (choice == 7 && square[7] == '7')
                     square[7] = mark;
              else if (choice == 8 && square[8] == '8')
                     square[8] = mark;
              else if (choice == 9 && square[9] == '9')
                     square[9] = mark;
              else
              {
                     cout << "Invalid move ";
                     player--;
                     cin.ignore();
                     cin.get();
              }
              i = checkwin();
              player++;
       } while (i == -1);
       board();
       if (i == 1)
              cout << "==>\aPlayer " << --player << " win ";
       else
              cout << "==>\aGame draw";
       cin.ignore();
       cin.get();
       return 0;
}
