Re: [Dev-C++] indirect references problem

[Per W. <pw...@ia...>]

Normally, you can break circular references by just adding the text:

class Police;

in the top of PoliceMan.h file and/or addding

class PoliceMan;

in the top of Police.h.

This adds the class to the known name space. However, this only works as
long as the compiler doesn't need to know the full size of the class.

So class Police can reference pointers or references to Police but can not
declare instances of PoliceMan, and can not access members or methods in
PoliceMan. The second part isn't a problem, since the file Police.cpp
(that have included both Police.h and PoliceMan.h) can access members and
methods of the PoliceMan class.
