abstract class c programming

What is abstract class in C?
Abstract classes act as expressions of general concepts from which more specific classes can be derived.
You can't create an object of an abstract class type.
However, you can use pointers and references to abstract class types.
You create an abstract class by declaring at least one pure virtual member function.
What is abstract in C programming?
An abstract type is one that's packaged to separate its functional behavior from its implementation.
This lets you use an abstract type with little or no regard for its underlying implementation.
Ideally, changes in the type's implementation should not change the way you use the type._{14 oct. 2003}
Abstract Classes and Methods
Abstract class: is a restricted class that cannot be used to create objects (to access it, it must be inherited from another class).
Abstract method: can only be used in an abstract class, and it does not have a body.
The body is provided by the derived class (inherited from).

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.
