Question
In C++ Implement a class to play the game of tic-tac-toe with two players. The class contains as private data member a 3 by 3 array of integers. The constructor should initialize the empty
board to zeros. When the first player moves, place 1 in the specified square; place 2 when the second player moves. Each move must be done in an empty square. After each move, determine if the game has been won or if the game is a draw.
A sample run follows.
000 000 000
Player1 move: 1 1 100
000
000
Player2 move: 2 2 100
020
000
Player1 move: 3 1 100
020
100
Player2 move: 1 1
1 1 is used. Please choose another move: 3 3 100
020
102
Player1 move: 2 1 100
120
102
The header, implementation and driver programs should be respectively named: TicTacToe.h, TicTacToe.cpp and TestTicTacToe.cpp
Can anyone help me please
