C++ (Tic-Tac-Toe) Write a program that allows two players to play tic-tac-toe ga

Question

C++ (Tic-Tac-Toe) Write a program that allows two players to play tic-tac-toe game. Your program must contain the class ticTacToe to implement a ticTacToe object.Include a 3-by-3 two-dimensional array, as a private member variable, to create the board.If needed, include additional member variables.Some of the operations on a ticTacToe object are printing the current board, getting a move, checking if a move is valid, and determining the winner after each move.Add additional operations as needed.

There are some additional requirements as well:

- Design the ticTacToe class object so that it is an ADT and provides information hiding. Assume that the game board will always be 3x3.

-The main .cpp file should ONLY contain a call to a public function (play) of the TicTacToe Class (Program will contain the main cpp and a header file as well)

All help is greatly appreciated

Explanation / Answer

1) tictactoe.h file contains

#pragma once

class ticTacToe{
private:
   char square[10];
public:
   ticTacToe();
   int checkwin();
   void board();
   void play();
};

2) tictactoe.cpp file contains

#include <iostream>
#include "tictactoe.h"
using namespace std;

ticTacToe::ticTacToe(){
   for(int i = 0; i < 10; ++i){
       square[i] = 48 + i;
   }  
}

int ticTacToe::checkwin(){
   if (square[1] == square[2] && square[2] == square[3])

       return 1;

       return 0;
   else
       return -1;
}

void ticTacToe::board(){
   cout << " Tic Tac Toe ";

void ticTacToe::play(){
   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')

   else
       cout<<"==>Game draw";

   cin.ignore();

3) tictactoemain.cpp file contains

#include "tictactoe.cpp"

int main()
{
   ticTacToe game;
   game.play();
   return 0;
}
