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

You include Animal.h in Treatment.h before the class Treatment is defined, that's why you're getting the error.

Use forward declaration to solve this:

In Animal.h add line

class Treatment;
