Write("I am here"); return -1; } public abstract void set_engine_id(int id); } // and then in the classes: // code c# class BIKE : VEHICLE { private int engine_id; public BIKE() {} public int get_engine() { return engine_id; } public override void set_engine_id(int id)...
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...
An abstract class in an unfinished class. It must be implemented in its subclasses. Abstract class is created with theabstractkeywords. We can create abstract methods and member fields. The purpose of an abstract class is to provide a common definition for descendant classes. Abstract classes cann...

Abstract classes (C++ only) Anabstract classis a class that is designed to be specifically used as a base class. An abstract class contains at least onepure virtual function. You declare a pure virtual function by using apure specifier(= 0) in the declaration of a virtual member function in...
1. Inabstractclasses this is not necessary that every method should beabstract. But ininterfaceevery method isabstract.在Abstract class中并非所有的method都必须是抽象的,但是在interface中所有的method都自动成为抽象的。就是在子类中必须声明和实现
abstract classand how to implement it? This article contains the brief description about Abstract Classes with examples. Submitted byAmit Shukla Use of abstract class In programming there are some condition occurs in which user want to define a super class that declare the structure of the given ...
In object-oriented programming, polymorphism is a powerful concept. Both interfaces and abstract classes are a means to implement polymorphism. They both contain abstract methods that classes can implement, and they both provide loose coupling in code. But what makes them different?
