A class that should never be instantiated; only its subclasses should be instantiated. Abstract classes are defined so that other classes can inherit from them

An abstract class contains at least one pure virtual function.

class AB {public: virtual void f() = 0;}; RegardsJeevs

abstract class is a class having at least one abstract method which does not have any functionality(code) in it.
The functionality will be given by its derived classes, until we derive a class to it we can't use the abstract method.
