The current project I am working on is getting rather large. I am trying to have a class with a large number of member functions in it, so that all I do is include the one file and then I can call the functions. I have a couple questions that I hope some of you more exerienced programmers can help me with: 1) Do I just have to do the #include "filename.cpp" thing to just the main source file or should I also include all the other files in the other file (the one with the class in)? 2) I am getting the error: fatal error C1076: compiler limit : internal heap limit reached; use /Zm to specify a higher limit. How do I go about fixing this? 3) Are there tutorials anywhere that explain this? 4) Can I call variables in the member functions that were globally declared in the other file? 5) Can I have one member function call another? I hope someone understands what I am trying to do/say...

1)put the prototypes in a .h file, and the implementation in a .cpp file
then you just need to #include the .h file anywhere that needs the functions
and dont forget to extern variables..

2).. strange... dunno

3)why would you need a tutorial?

4)see #1

5)yes

When you mean 'don't forget to extern variables', what is that and how would I go about doing it (just put the keyword 'extern' in front of my variable when I create it?). As you can tell, I'm not great with C++. I've been using it for less than a year.

ok sorry i was a little vague in my first post..

lets say you have a main.h and main.cpp, and a second.h and a second.cpp

second.cpp needs to access some of main.cpp's functions, variables, and vice versa

        
//BEGIN MAIN.H//

#pragma once //so it only gets compiled once


extern int X;
extern int Y;

void Something();
//END MAIN.H//


//BEGIN SECOND.H//

#pragma once

extern int Bla;

int Function();
//END SECOND.H//


//BEGIN MAIN.CPP//

#include "main.h"
#include "second.h"

//you must put variables in here as well, without extern
int X=0;
int Y=0;
void main()
{
    Something();//belongs to main.h

    Function();//belongs to second.h

}

void Something();
{
return X*Y;
}

//END MAIN.CPP


//BEGIN SECOND.CPP//

#include "main.h"
#include "second.h"
int Bla;
void Function()
{
return Bla*2;
}
//END SECOND.CPP


..geez.. i hope you can understand that

I''m pretty sure that error C1076 is caused by an include file that includes itself, which causes infinite recursion. ...or something like that.
