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.
Read moreWhat is an abstract class with example?
Abstract classes are essential to providing an abstraction to the code to make it reusable and extendable. For example, a Vehicle parent class with Truck and Motorbike inheriting from it is an abstraction that easily allows more vehicles to be added .
Read moreWhat is meant by an abstract class?

Read moreWhy do we use abstract class in OOP?
One of the fundamental concepts in OOP is the abstract class. Abstract classes cannot be instantiated and are designed to be subclassed. They are used to provide some common functionality across a set of related classes while also allowing default method implementations .
Read moreWhat is purpose of abstract class?
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.
Read moreIs abstract a keyword in C?
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.
