Tic Tac Toe

hey,
This is the first game ive made in C++ im still in Middle School so im not sure how itll be, so far there are no graphics and all its just text, but I want to make sure that my code works before i implement the graphics. So could you guys just run it and make sure that the win and draw things are working and that ther are no combinations that arent working. (Dont look at the main() code I know its shit but its just temporary until I get graphics). Could you just compile the code and run it? (I made it in Turbo C++, so if you get any errors in DevC++ could you fix them? ) Thanx alot.
EDIT: Large blocks of code should be wrapped in 'source' tags...

sorry about no indents, its not letting me do them
Also, I'm going to push this over to 'For Beginners' - Maybe someone there will be so kind as to offer you a code review. I can't really see any reason why this landed in DirectX [smile].
Cheers,

There were a few things that I really didn't like about your code. Your use of goto(not really needed) and the fact you didn't use a game board in your code. It was very hard to figure out how your code worked without comments as well, so I decided to just write my own tic-tac-toe game to offer some measure of inspiration.
This code isn't nearly the best, just something quick and dirty I wrote up to better show how you might organize your code. It makes use of vectors for the board, and strings for anything input related. If you want to know how things like vector, string, getline, etc works, just do a search for something like "vector c++ tutorial" and you'll likely get a good result.
This was written in Code::Blocks, with the mingw compiler.

Thank you for taking the time to write out a whole program :). I was looking at your comments and the gotos in the main function were only temporary until I implemented a whole graphics interface (which I am working on right now). Basically my program initializes all 9 squares to values in a array by the users input. I then derived an alogorithm of possible wins by tic tac toe and my program checks that if the values of the arrays fit into the equation through the use of for loops nd ifs.
So having goto's is an excuse for not using graphics? Wonder how all the textbased rpg's would look like :-)
