Abstract base class c is a type of class from which other classes can inherit and construct objects. It does not provide any implementation for its interfaces, but it defines which methods must be present in its subclasses. This allows for code reuse and greater flexibility when extending classes.

What is an abstract base class?
An abstract base class is a type of class from which other classes can inherit. It does not provide any implementation for its interfaces, but it defines which methods must be present in its subclasses.
What are the benefits of using an abstract base class?
Using an abstract base class offers several benefits, such as code reuse and greater flexibility when extending classes. It also encourages consistent coding practices across applications.
Is it possible to create objects from an abstract base class?
No, it is not possible to create objects from an abstract base class since it does not provide any implementation for its interfaces. Instead, the abstract base class must be subclassed and concrete objects created from the subclass instead.
What types of methods can be defined in an abstract base class?
Any types of methods that are required to in order for subclasses to extend the functionality of the parent can be defined in an abstract base class. This could include constructors, getters/setters, or various other utility functions that are needed by its subclasses.
Does every subclass need to implement all methods defined by the abstract base class?
Not necessarily - only those methods that are required by the subclasses need to be implemented by each individual subclass, while additional methods need not be implemented if they are not applicable to a particular subclass.
Conclusion:
Abstract Base Class c is a powerful tool that enables developers to extend existing classes without having to duplicate code or refactor existing application components. By defining certain interface requirements up-front, it ensures greater consistency across applications while still allowing developers to tailor each particular solution according to their own unique needs and preferences.
