Polymorphism is implemented via:
A) Member functions.
B) virtual functions and dynamic binding.
C) inline functions.
D) Non-virtual functions.

Question

Quizplus · Accepted Answer

Polymorphism is achieved through virtual functions and dynamic binding. Virtual functions allow the pointers of superclass to point to the objects of a subclass, and dynamic binding ensures that the appropriate function gets called at run-time based on the object being pointed to. Member functions and non-virtual functions cannot achieve polymorphism as they are resolved at compile-time, and inline functions are a different concept altogether.
