Q1. 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 be used for different data types or classes.

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

Q3. Explain inheritance and it types
Ans. 
Inheritance is a concept in object-oriented programming where a class inherits properties and behaviors from another class.
• Inheritance allows a class to reuse code from another class.

• Types of inheritance include single inheritance, where a class inherits from only one parent class, and multiple inheritance, where a class inherits from multiple parent classes.

• Example: Class B inherits from Class A, so Class B can access
