Gw mau tau Conto 2 dari Class (élmu komputer). Jelasin dalam bahasa sunda

virtual void MyVirtualMethod() = 0;

class Concrete : public Abstract

An object of class Abstract can not be créated because the function MyVirtualMethod has not been defined (the =0 is C++ syntax for a pure virtual function, a function that must be part of any derived concrete class but is not defined in the abstract base class. The Concrete class is a concrete class because its functions (in this case, only one function) have been declared and implemented.
