[PDF] abstract class in c++

An abstract class is a class that is designed to be specifically used as a base class. An abstract class contains at least one pure virtual function. You declare a pure virtual function by using a pure specifier ( = 0 ) in the declaration of a virtual member function in the class declaration.

  • Why abstract class is used in C++?

    Abstract classes are used to express broad concepts from which more concrete classes can be derived. An abstract class type object cannot be created. To abstract class types, however, you can use pointers and references. Declare at least one pure virtual member feature when creating an abstract class.23 fév. 2023

  • What is 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.
  • Can we write abstract keyword in C++ class? Sure, we can do it. Unfortunately the code will not compile, though =)
