A pure virtual function is a function that must be
overridden in a derived class and need not be defined. A
virtual function is declared to be "pure" using the
curious "=0"

syntax:

class Base {
public:
void f1(); // not virtual
virtual void f2(); // virtual, not pure
virtual void f3() = 0; // pure virtual
};
