Tic Tac Toe is one of the few games that transcends cultures and continents, it is easily understood and cost nothing to play.

• Two players are required for a game.
• Each player will assume wither an “X” or “O”.
• Players take turn to play till a player wins, or the end of the game (whichever happens first).

• A player wins when all fields in a column are taken by the player.
• A player wins when all fields in a row are taken by the player.
• A player wins when all fields in a diagonal are taken by the player.

The game is drawn when all fields are taken on the board.

We are going old school.

You need to implement a console based version of Tic Tac Toe that allows two human players to play the game on a 3 x 3 board.

It's really simple... The first player will be the X, the second player will be the O. You keep playing the game until there is a winner, a draw, or someone gives up.

An example run through of a game console would be...
