What is a pure virtual function? What is the difference between new and override? If the class implements an inheritance, and then thereby inherits all the abstract methods of an interface. Means, it shows only required details for an object, not the inner constructors, of an object. There will always be only one copy constructor that can be either defined by the user or the system.
