DESCRIPTION Create a program using a two dimension array and functions that lets two players play the tic-tac-toe game. The program is to read a number from 1 to 9 from the keyboard alternating between the X and the O. Ask which square the X player wants, and then ask which square the O player wants. Continue until the game is won by either player, or all the squares have been filled. (Called a Cat's Game or a Tie Game)

A function must be used to display the tic-tac-toe game board, and a function must be used that determines if the game has been won. You can create the program on your own, or start with the sample code provided.

EXTRA CREDIT (3 points) Modify the DisplayTicTacToe( ) function using the | and characters to draw lines for the tic-tac-toe display.

This a part of the code, if you can find whats missing it would be awesome thank you.
