Can someone with a brain point out something here...

Because apparently I don't have one. This code is from Teach Yourself C++ in 21 Days, listing 5.7, which is supposed to be written with the ASCII standard. I get the error message ISO C++ forbids declaration of ' from Dev C++ on line 25 (an opening brace for the function VolumeCube). The code is exactly as it appears in the book, save for "using namespace std". Thanks in advance.

Code:

#include <iostream>
using namespace std;

int VolumeCube(int length, int width = 25, int height = 1);

int main()
{
    int length = 100;
    int width = 50;
    int height = 2;
    int volume;
    
    volume = VolumeCube(length, width, height);
    cout << "First volume equals: " << volume << "\n";
    
    volume = VolumeCube(length, width);
    cout << "Second time volume equals: " << volume << "\n";
    
    volume = VolumeCube(length);
    cout << "Third time volume equals: " << volume << "\n";
    return 0;
}

VolumeCube(int length, int width, int height)
{
    return (length * width * height);
}

Code:

int VolumeCube(int length, int width, int height)
{
    return (length * width * height);
}

So easy to make those mistakes

Your implementation of VolumeCube() lacks a return type. Type int next to it.

@#$! my eyes! Thank you. Apparently I need to get my glasses checked....

Well I guess I can't help.

IT works perfect on VS 6.0 No further changes needed... regards

So what does that tell you about
a) the book in question
b) your compiler.
For me, it tells me that the book and VS6 have the same bug.

intresting if you can speak german refer here

No se habla en ingles; and no speak Chinese either....

Yeah, this is a old copy of that book, I got it off a discount rack for $3... Even as little as I know about C++, I've seen some goofball mistakes in the code here and there, mostly just typos. That was one that I didn't catch for some reason...

I do know that some compilers, such as Borland's, have their own dialect of C++ that they may use instead of ANSI. I have Borland's IDE as well, and I never could get it to accept a single bit of ANSI-compliant code; in either C or C++; from various sources both in books and online. I finally gave up and got Dev C++; which is having it's share of problems as well now.

Thank y'all for all the help.

>> ...Dev C++; which is having it's share of problems as well now.
Well, failing to compile invalid code isn't exactly a problem in my book

If Dev C++ (which uses the MinGW port of GCC) fails to compile some code from that book - you can safely assume the book is incorrect or you typed it in wrong.

Actually, it was about a dozen versions or so out of date. Though I'm beginning to think I was ripped on the book. I've gotten to chapter 6, which is implementing basic classes and setting them up as include files. Unfortunately, the second program that you build a custom include for is so seriously messed up it isn't even funny. I'm going to look around on this site for a tutorial on classes, and see how to fix this mess. I'm getting around 100 error messages right now; after I combined the .hpp file into the source so I could see if the compiler simply didn't like me leaving my custom includes in their own folder on e:\. Only 25 or so before hand in the source... The ones I can see are missing functions being called here and there.

Whats some good recommendations for books? I do have a more advanced book on low-level interrupts and functions which weighs about the same as a 340 six pack, but I kinda doubt I'd be able to do much more than get a headache and some frustration with that.

$3 will buy you a decent sandwich. Decent sandwiches are worth their weight in gold.

Accelerated C++ by Andrew Koenig and Barbara Moo.

If you are looking for good cheap books take the suggestions from the people on this board and then go to amazon.com and check out to see if they are selling a used copy of the book.

I started doing it to get books that weren't in print anymore but I now buy the majority of my books that way. I have never had any complaints and most of the time you can get the books for around 30% - 50% off the list price.

I just got 2 books... for $12

Mathmatics for 3D Programming & Computer Graphics

Sam's Teach Yourself Game Programming in 24 Hours

Thanks y'all. I have ordered from Amazon before; not much though. The only book I really want is close to $30 used.
