Web10 Often times it's a good idea to have an abstract base class to isolate the interface of the object. The problem is that copy construction, IMHO, is pretty much broken by default in C++, with copy constructors being generated by default. So, what are the gotchas when you have an abstract base class and raw pointers in derived classes? WebThe differences between a class and a struct in C++ are: struct members and base classes/structs are public by default. class members and base classes/structs are private by default. Both classes and structs can have a mixture of public, protected and private members, can use inheritance, and can have member functions. I would recommend you:
