What is runtime polymorphism in C++?

Answer 1

Simply put, runtime polymorphism is the ability of C++ to determine the class of an object that belongs to a derived class. RP allows a designer to write a base class and derived classes and then create objects of the derived classes pointed to by pointers to the base class. RP will figure out what derived class the object belongs to. Why is this important? Because it allows the designer to write simpler code.
