Tic Tac Toe Program
The tic-tac-toe game is played on a 3x3 grid. The game is played by two players, who take turns. The first player marks moves with a cross, the second with a circle. The player who has formed a horizontal, vertical, or diagonal sequence of three marks wins. This program draws the game board, ask the user for the coordinates of the next mark, change the players after every successful move and display the winner.
