abstract class in c++

Why do we use abstract class in C#?
The purpose of an abstract class is to provide a common definition of a base class that multiple derived classes can share.
Why do we use abstract class 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 an abstract class example?
An abstract class can have constructors like the regular class.
And, we can access the constructor of an abstract class from the subclass using the super keyword.
For example, abstract class Animal { Animal() { …. } }
Abstraction is one of the most important concepts of object-oriented programming.
It refers to showing only relevant information to the outside world.
In simple words, we can say it means hiding any background information from the outside world.

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.
