Answer / govind verma

there are mainly two types of inheritance--
1) Implementation inheritance--when a class is derived from
another class such that it inherits all the members of base
type.
2) Interface Inheritance--when a type inherits only
signature of functions of another type . it does not uses
constructor.

Answer / sudheer

An interface has all public members and no implementation. An abstract class is a class which may have the usual flavors of class members (private, protected, etc.), but has some abstract methods.

Answer / naag algates

1. Derived class can inherit from only one base class(because no multiple inheritance)
2. Base class(or any class) can inherit any number of interfaces.
3. Single class can support multiple interface and multiple class can support same interface.

Answer / kanan

1) C# doesn't support multiple inheritance, by inheriting
interface we can overcome this problem, as we can inherits
as many interface as we want.

2)implementation of class methods is not must like interface.
