An abstract class is used if you want to provide a common, implemented functionality among all the implementations of the component . Abstract classes will allow you to partially implement your class, whereas interfaces would have no implementation for any members whatsoever.

So, abstract classes can be used to consolidate and share functionality , while interfaces can be used to specify what the common functionality that will be shared between different instances will be, without actually building that functionality for them. Both can help you make your code smaller, just in different ways.

The purpose of an abstract class (often referred to as an ABC) is to provide an appropriate base class from which other classes can inherit . Abstract classes cannot be used to instantiate objects and serves only as an interface. Attempting to instantiate an object of an abstract class causes a compilation error.

abstract (C++/CLI and C++/CX) The abstract keyword declares either: A type can be used as a base type, but the type itself cannot be instantiated . A type member function can be defined only in a derived type.
Read moreWhat is an abstract method C#?
An Abstract method is a method without a body . The implementation of an abstract method is done by a derived class. When the derived class inherits the abstract method from the abstract class, it must override the abstract method. This requirment is enforced at compile time and is also called dynamic polymorphism.

An abstract class is a class that is declared abstract —it may or may not include abstract methods. Abstract classes cannot be instantiated, but they can be subclassed.
Read moreWhat is abstract class data type?
Abstract Data type (ADT) is a type (or class) for objects whose behaviour is defined by a set of value and a set of operations . The definition of ADT only mentions what operations are to be performed but not how these operations will be implemented.
