In abstract class, we use abstract keyword to method but in polymorphism uses virtual keyword to base class method.
What are the 4 basics of OOP?
Now that we have covered these keywords, let’s jump into the four principles of object-oriented-programming: Encapsulation, Abstraction, Inheritance, and Polymorphism.
What is difference between inheritance and polymorphism?
Inheritance is one in which a new class is created (derived class) that inherits the features from the already existing class(Base class). Whereas polymorphism is that which can be defined in multiple forms. Whereas it can be compiled-time polymorphism (overload) as well as run-time polymorphism (overriding).
What is it called if an object has its own lifecycle and there is no owner?
