I have a C++ application.This supports users\' C++ plugin DLL\'s, it will dynamically load these DLL\'s and then be able to create and use the user\'s types dynamically. These user types derive from b
I have some code where classes inherit from a base class. That base class has a function which, when run, ought to call functions to be implemented by the children. That is, the general algorithm is
I have a multiple inheritance scenario without virtual base classes like this: TaTb BC \\ / A Ta and Tb are two different template classes that both declare a virtual function named f(). I wa
I am reading some C++ text regrading Pure Virtual Functions. As the text says, the form of Pure Virtual Functions declaration, for example, is:
Following this question, I\'m wondering why a struct\\class in C++ has to have a virtual method in order to be polymorphic.
