Q3. What is Polymorphism
Ans. 
Polymorphism is the ability of a function or method to behave differently based on the object it is acting upon.
• Polymorphism allows objects of different classes to be treated as objects of a common superclass.

• It enables a single interface to represent multiple data types.

• Examples include method overloading and method overriding in object-oriented programming.
