A virtual function is a function member of a class,
declared using the "virtual" keyword. A pointer to a
derived class object may be assigned to a base class
pointer, and a virtual function called through the pointer.
If the function is virtual and occurs both in the base
class and in derived classes, then the right function will
be picked up based on what the base class pointer "really"
points at.
