Q3. What is polymorphism principle?
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 be used for different data types or objects.

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