Define Classification of Inheritance supported by C#:

1) Implementation Inheritance:

•  This is commonly used inheritance.
•  Whenever a class is derived from another class, it can be called as ―Implementation Inheritance.
•  As said above, all of the members of the super class are adopted by sub class.

2) Interface Inheritance:

•  This type of inheritance is taken from ―Java.
•  Whenever a class is derived from an interface, it can be called as ―Interface Inheritance.
•  The interface is similar to the class, but doesn‘t contain the method definitions; it contains the method declarations only. We discuss about the interfaces in-depth later.
