(C++) Write a console program that plays Tic Tac Toe with the user.

The program displays a 3 by 3 grid, which is initially blank. When the player takes a turn, an X is added to the grid. When the computer takes a turn, a O is added to the grid. After each turn, simply print out the grid. As a result, old states of the grid will scroll up in the console window.

After each turn, your code needs to check for a win or a tie. If either of these conditions are met, then the program displays the result and terminates.
