-TicTacToe 2D Arrays - C++

I coded this yesterday because I realized I haven't really created any game with C and because many people here are looking for 2d arrays help. This is a basic tic-tac-toe game with customizable size. You can make it 3x3, 5x5, 10x10 - your wish - by changing the rows and columns preprocessors to your like. This source could be helpful for beginners, like myself, trying to learning multi-dimensional arrays.

Also, for all of those who are using system("CLS"). I've included an alternate function using windows functions. Basically, it gets the output handle to the screen and gets the number of characters on the screen and fills them with ' '(spaces). Done.
