Polymorphism as a tool for updating software
If class A declares a virtual member, and class B derives from A, and class C derives from B, class C inherits the virtual member, and has the option to override it, regardless of whether class B declared an override for that member.The following code provides an example: to call the base class implementation of that member in their own implementation.If you need more information on the Dev Ops you can browse other free and exciting content from edureka from the above links mentioned on the blog.
Polymorphism is often referred to as the third pillar of object-oriented programming, after encapsulation and inheritance.

If the base class implementation is not called, it is up to the derived class to make their behavior compatible with the behavior of the base class.oriented programming, after encapsulation and inheritance.
The designer of the derived class can choose whether to A derived class can override a base class member only if the base class member is declared as virtual or abstract.
The derived member must use the override keyword to explicitly indicate that the method is intended to participate in virtual invocation.
