Question

In a game of tic-tac-toe, two players (one the computer) take turns marking an available cell in a 3 X 3 grid (a two dimensional array) with their respective tokens (either and X or an O). When one player has placed three tokens in a horizontal, vertical, or diagonal row on the grid, the game is over and that player has won. A draw (no winner) occurs when all the cells on the grid have been filled with tokens and neither player has achieved a win. Create a program for playing tic-tac-toe as follows:
