What are virtual functions?

A virtual function allows derived classes to replace the implementation

provided by

the base class. The compiler makes sure the replacement is always called

whenever

the object in question is actually of the derived class, even if the object is

accessed

by a base pointer rather than a derived pointer. This allows algorithms in the

base

class to be replaced in the derived class, even if users don't know about the

derived

class.
