trouble creating a *.h file

[QWERTYman]

#ifndef AVG_H_
#define AVG_H_

float aver(float a1st, float a2nd, float a3rd){
    return (a1st + a2nd + a3rd)/3;
}

For some reason, the file refuses to compile. Any ideas?

[psault]

You need to add to the end of your header definition:

#endif


That might be why.

No.

The file doesn't have any errors, just won't compile AT ALL. Won't even try to compile.

[psault]

When you create a .h file, then you have a program that depends on it, you need to have the .h file available to your program (probably in the same directory as your .cpp file) and include it like:

#include "avg.h"

Of course you need to save that file as avg.h

Try compiling the .cpp code that depends on that header file after you do that.

TY.

Also, any way so that a BUNCH of numbers can be used in my aver() function?

[Zaita]

You can use a dynamic argument list. In much the same way printf does it or main does it.

Google C++ dynamic argument list.

[QWERTYman]

Don't get it. Dynamic Argument List = Greek to me.

Ty.

Wow, the board has changed a lot.

[QWERTYman]

Wow, new problem. That link only covered void functions. What if I wanted to do function with a return value?

[Zaita]

It's exactly the same, just with a different return type.

void something() { }

bool somethingelse() { return true; }

[QWERTYman]

Aye, but say I wanted to return the sum of the arguments / number of arguments.

How can I make the program know how many arguments?
