About the game: this program is designed for two (2) players to play the tic-tac-toe game. The players will be presented
                with a template grid used for playing the game.
                Player one (1) will use the (x) character and Player two (2) will use the (o) character
                
                The procedure for the game are as follows:
                    1) player 1 will input (x)  first into one of the 9 boxes
                    2) player 2 will input (o) second into one of the 9 boxes which previous player did not use
                    3) repeat steps until


 rules: a template of the grid is below
        in that grid: number 1-9
        system statement :\ - cls

           prompt player 2

           }
