According to what I learned on Google, it is used as a superclass (base class) of classes with the same nature such as type, type, and task. The abstract class provides a template for implementing data abstraction by hiding implementation details. Abstract classes can declare normal properties and methods and do not have abstract properties (abstract classes do not allow parameter initialization,

You cannot create instances for abstract classes so answer is 0.

Answer is 0

We cannot create an instance of an abstract class as it does not have any complete implementation.
An abstract class acts like a template or an empty structure.

You cannot create instances for abstract classes. So, the answer is zero.

This is because an abstract class does not have complete implementation.
