Как установить эту функцию, чтобы настроить ход игрока?

Question

Я пытаюсь настроить ход игрока, используя этот источник main () от нашего инструктора:

Наше задание указано на этом сайте: http://itweb.fvtc.edu/ag/?u=3&f=cpp-assignment5

вот источникcode:

#include <iostream>
#include <conio.h>

#include "TicTacToe.h"

using namespace std;

int main()
{
    TicTacToe *pGame = nullptr;

    while (true)
    {
        if (pGame) delete pGame;
        pGame = new TicTacToe;

        // play the game
        while (!pGame->IsOver())
        {
            pGame->DisplayBoard();

            int position;
            do
            {
                cout << "Player " << pGame->GetPlayerTurn() << ", select a position (1-9): ";
                cin >> position;
            } 
            while (!pGame->IsValidMove(position));

            pGame->Move(position);
        }

        // game over
        pGame->DisplayBoard();
        pGame->DisplayResult();


        // prompt to play again (or quit)
        char input = ' ';
        while (input != 'Y' && input != 'y')
        {
            std::cout << "Would you like to play again? (y/n): ";
            cin >> input;

            if (input == 'N' || input == 'n') return 0; // quit
        }
    }
}

Я получил этот код файла заголовка для компиляции игры, но функция вызова для использования хода игрока не работает, как я хотел. Что я здесь не так делаю?
