CONCEPT
--------------

Pure Virtual Function

When you have a pointer to an object, the object may actually be of a class that is derived from the class of the pointer (e.g., a Vehicle* that is actually pointing to a Car object; this is called “polymorphism”多态性).

Dynamic binding is a result of virtual functions.
