RES: [Dev-C++] errors

Try putting your includes like this:
#include <iostream.h>
#include <string.h>
And I noticed the identifiers you're using in the enum type:
enum SquareState { blank = ' ' , X = 'X', 0= '0' };
Look: you're using 0 (zero) instead O (letter). Identifiers shouldn't start
with a digit, like 0 (zero).
The same where you're returning zero instead O.
Hope this can help you.

HEY GUYS,
I'm that newbie guy that keeps having trouble. I got a book "C++ for the
absolute beginner," well this beginner doesn't still get it. So I'm
wondering if you can explain what the book is failing to explain. Below is
a program I typed in, that is giving me fits over "enum" and all its
"returns" I feel like I missing something in my lib.'s but I'm not sure. I
have double checked everything several times to the book and from all that I
can see I have typed it out just as the book has it. I take it though one
complier will do things differently than another and I know the author is
using a different complier. So if anyone can help me I'm all ears.
THANKS DANNY!!
