So, I got 2 different .cpp file(human.cpp and pet.cpp) (I can't create header file for class definition)
Human object has pet as its private instance.
In the pet class, I define this struct:
and pet object has vector of toy as its private instance. So far, it works just fine. However, in the a function in human class that pass toy object? how can I possibly do this? should I define the struct toy in human class? thx
yeah that's what I write. However, I separate pet class and human class into 2 different .cpp file. what should I put in the #include in the human class? because I don't have any pet.h class. thank you
In C/C++ there's syntactically no need for special specification/implementation files like in modern high-level languages. But usually specifications like those above will be put in header files one file for each class. By convention the files prefixes are named by the classes name. On top of "Human.h" you will include "Pet.h". Your example will only need an implementation file "Human.cpp" to define implementation of f().
