Abstract classes can be created, signified, or simulated in several ways: By use of the explicit keyword abstract in the class definition, as in Java, D.

We can't create a instance class for abstract class and once we mention the class is abstract even we can't create the object for that class.

To access a member function of abstract class we need not require a object. By creating a pointer of object we can call it or access it.

According to me. We cannot create the object of the abstract class but we can create many time instances of the abstract class.

The abstract class contains at least one pure virtual function.
The pure virtual function by using a pure specifier ( = 0 ).

Abstract class is not a main class to automatically create a object, only create reference to that particular class itself.

In my view a parent class does not have any direct instance it means abstract class can be used to creation of subclasses.

When a class is act as a parent class for all other classes and it should not be get instantiated by any derived class.

Abstract Class is act like a base class to the derived classes;
So, we can't create any instance to Abstract class.
So, we can't create any instance to Abstract class.
