Answer / kiran

Following are features of a abstract class :-
&#8730; You can not create a object of abstract class
* How would you describe yourself ?
98
&#8730; Abstract class is designed to act as a base class (to be
inherited by other classes).
Abstract class is a design concept in program development
and provides a
base upon which other classes are built.
&#8730; Abstract classes are similar to interfaces. After
declaring an abstract class, it
cannot be instantiated on it's own, it must be inherited.
&#8730; In VB.NET abstract classes are created
using “MustInherit” keyword.In C#
we have “Abstract” keyword.
&#8730; Abstract classes can have implementation or pure abstract
methods which
should be implemented in the child class.
