. Explain the term polymorphism as applied in OOPS

Polymorphism is a concept in object-oriented programming (OOP) that allows objects of different classes to be treated as objects of a common superclass. It enables a single interface to be used for different types of objects, providing flexibility and reusability in code.

Here are the steps to understand polymorphism in OOP:

1. Inheritance: Polymorphism relies on the concept of inheritance, where a subclass can inherit properties and methods from a superclass. This allows objects of different classes to share common attributes and behaviors.

2. Method Overriding: Polymorphism is achieved through method overriding, which is the ability of a subclass to provide its own implementation of a method that is already defined in its superclass. This means that objects of different classes can have different behaviors for the same method.

3. Dynamic Binding: Polymorphism also involves dynamic binding, which is the process of determining the appropriate method to be called at runtime. This allows the program to decide which implementation of a method to use based on the actual type of the object, rather than the declared type.

4. Common Interface: Polymorphism requires objects of different classes to implement a common interface or inherit from a common superclass. This allows them to be treated uniformly, regardless of their specific types.

5. Code Reusability: Polymorphism promotes code reusability by allowing the same code to be used for different types of objects. This reduces the need for duplicate code and improves the maintainability of the program.

In summary, polymorphism in OOP allows objects of different classes to be treated as objects of a common superclass, providing flexibility, reusability, and a unified interface for different types of objects.
