Critique this code (my own simple tic tac toe)

[IAmPat]

I'm kind of teaching myself C++ from the ground up. I have previous programming experience in PHP, VB, Javascript, .net and i've done some other small stuff here and there but i've been putting off C++ for way too long and feel like I really need to learn it in-depth.

This is some code that I whipped up for a basic tic-tac-toe game. I'm just looking for some pointers and some constructive criticism of my code. Keep in mind i'm new to C++ and this is really only coded with a days knowledge of the language plus some previous coding experience.

Thanks

>>and some constructive criticism
ok, here goes

>> void main()
never use it. Read this:

lines 13-19: that an onconventional way to initialize variables. It will work, but that form is rarly ever used. more commen is int iTurn = 1; "\n" is usually preferred to endl because endl also performs unnecessary flush.

And format your code. It's too hard to follow with inconsistent spacing.

[mitrmkar]

First things first, I second to WaltP, really format your code to make it readable. Now it's close to unreadable.
Arrays are zero-indexed .. hence both of your string arrays now have an unused index 0, in other words, you should do with smaller (by one) string arrays.

string squares[] = {"1","2","3","4","5","6","7","8","9"};
instead of 
string squares[] = {"0", "1","2","3","4","5","6","7","8","9"};

You could throw away the squares array, since you only use it to validate that user's move is within the accepted bounds (I haven't seen a similar construct before). You might do better by getting an integral value instead of strMove (and throwing away the for loop too).
Using arrays of std::string is a bit heavy-duty solution, a more simple type as char would serve as well.
