Is this possible in C++? toString(ClassName* class)

Question

I\'d like to use toString with class argument, but for some reason there is an error. The code is:

Animal.h

#include \"Treatment.h\"
#in         


        

Answer 1

// Animal.h
// #include "Treatment.h"   remove this

class Treatmemt;    // forward declaration

class Animal
{
    ...
};

In your version, Treatment.h and Animal.h include each other. You need to resolve this circular dependency using forward declaration. In .cpp files, include all necessary h-files.
