Why having function in my class doesn’t change size of this class? This info must be stored somewhere, but where?
You can think of a member function as being just like any other function, except that it has an extra, hidden parameter that takes a pointer to the instance on which the member function was called.
For example, this:
might be implemented (at least conceptually) as:
If it was a const member function, then the hidden parameter would have the type
const C*instead. Note that the situation isn’t nearly this simple for virtual member functions.
