Contrast the use of an abstract base class against an interface?..

Answer / abhishek

Basically both Interfaces and Abstract class sit on top. An
abstract class can have defintion and body. It's also used
when we need to implement polymorphism (Contain at least one
virtual method). However an interface contains only
declaration.

An Abstract inherit a class, an abstract class and implement
an interface. But interface can only implement another
interface.
