Still fairly new to c++ so this problem is stumping me. I get what I'm supposed to do but the logic is what's causing me trouble. If anyone can help me out that would be great.

- write one program that uses two dimensional array to allow two players to play tic-tac-toe. The program asks for moves alternately from player X and player O to enter a number (1 - 9) they wish to makr to play the game.The program displays the game positions as follows: 1 2 3 4 5 6 7 8 9 After each move, the program displays the changed board, for example: X X O 4 5 6 O 8 9 - the program should have following functions: -- a function to take in user's input. -- a function to print out the board and move. -- a function to tell if game is over. -- a function to tell who wins (or draw.) 

Please follow the requirements as stated in the problem, so using a 2D array and having four functions. Comments would be very helpful.
