rekursive include 1

[DerStephan]

Hi,

i have a little problem...
I have 2 classes in seperate cpp files with header files. Maybee classA and classB
classB carries an instance of classA

...
class classB
{
public:
classA memCA;
}
...

now what I want is a pointer on classB in classA
class classA
{
public:
classB* mempCB;
}
...

now the funny problem with the including of each others headerfile... I have in each haeder something like

#include "classB.h"
#ifndef _classA
#define _classA
class classA
...
#endif

and for classB the other way around.

I don't know what to do to prevent this all from rekursive including, this problem drives me crazy.

Any suggestions?

Thanks in advance

Stephan

PS: I really need to have this pointer...

You just need to declare the class without defining it to let classA know that it exists. At the top of classA.h, just add the line "class classB;" before you define classA. Then go ahead and #include the actual classb.h file in the classA.cpp file. This should fix the problem.

Just a prototyp class.

I think that will work.

Thanks for that prompt reply!!!

But look at your design, its not really good to have a referencing B when B references A
