This means if there are two classes inheriting from an abstract class, both classes should provide the implementation of a pure virtual function; otherwise, they will become abstract. It ensures that the necessary function is implemented in every class. Enroll in Intellipaat’s C Programming ...

If a suitable default definition is likely to be applicable to all Aquariums then by all means define it in the Aquarium class, but you might not want to make it pure virtual otherwise all derived classes would still have to override it even if they just wanted to call the base class imp...
C# / C Sharp 5 What does extending a class mean? by: needin4mation | last post by: Hi, I read this in a book about the Xml classes in c#: "These classes are abstract and therefore must be extended." I just wanted to know what this statement means. I know it is not in....

A common interview question for programmers is: What's the difference between an interface and an abstract class? Let's take a deep dive and explore the two!In object-oriented programming, polymorphism is a powerful concept. Both interfaces and abstract classes are a means to implement ...
The abstract keyword in C# creates incomplete classes and class members. The sealed keyword prevents inheritance of previously virtual classes or class members.
The implementation of this feature in JavaScript should be similar to the implementation of interfaces, abstract methods and static methods. This means that: Declaring abstract static methods in an abstract class should not affect the representation of the abstract class in the JavaScript code. ...
In short as I understand it, an interface is like a contract between the class and the interface, so that certain funtions must be implemented. So if you have a class which inherits base class that inherts an interface, then your classes will have a standard. I suppose you can also che...
