Problem: You need to get a specificProgramAll the Assembly referenced by the set. This information tells you whether the Assembly is referencing one or more of your created assembly, or whether your assembly is referencing other specific assembly.

The role of virtual functions in C ++ is to implement the polymorphism mechanism. With regard to polymorphism, in short, the pointer of the parent type points to the instance of its subclass, and then calls the member function of the actual subclass
