B) overridden
C) virtual
D) overloaded

Question

Quizplus · Accepted Answer

C++ provides virtual functions for polymorphism in an inheritance hierarchy. Virtual functions are functions that are declared as virtual in the base class and can be overridden in the derived class. The appropriate member function is selected at run-time based on the actual object that is being referred to, rather than the type of the pointer or reference used. This allows for dynamic binding and makes it possible to write code that works with objects of different classes without knowing their precise type.
