It gives that error: prg.cpp: In constructor ‘ThresholdPrerequirement::ThresholdPrerequirement (int)’: WebAccepted answer. No, you cannot access derived_int because derived_int is part of Derived, while basepointer is a pointer to Base. You can do it the other way round though: Derived* derivedpointer = new Derived; derivedpointer->base_int; // You can access this just fine. Derived classes inherit the members of the base class, not the other way ...

WebClasses that are derived from others inherit all the accessible members of the base class. That means that if a base class includes a member A and we derive a class from it with another member called B, the derived class will contain both member A and member B. The inheritance relationship of two classes is declared in the derived class.

WebJul 13, 2013 · It's a tricky case but I think the problem can be summarized as trying to use a protected member function pointer as a template parameter to a function that does not have access to that member.
