The errors you are getting are all due to simple typing errors. If you =
look in the enum you have substituted the number 0 with the letter O, =
notice the subtle difference in width between letter and number. So =
where you have previously put zero you need to put the letter O, but =
only for the lines dealing with the enumeration, and returning an =
enumeration type. Another mistype you have is where a ) bracket has been =
substituted for a } brace.
If you go through the errors double clicking the top one and correct the =
error, and then recompiling eventualy you will get a full compile. =
However I suggest you look at the code as the game doesn't apear to work =
properly, so there may be other more subtle erros, maybe mistyped =
numbers etc...

Subject: [Dev-C++] errors
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. =20
THANKS DANNY!!
