in the C++ programming language, write a program capable of playing 3D Tic Tac Toe against the user. Your program should use OOP concepts in its design. The program should randomly decide who goes first computer or user.Your program should know and inform the user if an illegal move was made(cell already occupied). It should keep score and announce whether a player has won/lost/draw. It should be on a 3x3x3 board. --OOP as in utilizing classes/methods/inheritance etc.

Answer:-

Tic Tac Toe Program :

#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;
}
