Q1. What is inheritance
Ans. 
Inheritance is a concept in object-oriented programming where a class can inherit attributes and methods from another class.
• Allows for code reusability by creating a new class based on an existing class

• Derived class (subclass) inherits properties and behaviors from a base class (superclass)

• Can have multiple levels of inheritance, creating a hierarchy of classes

• Example: Animal class can be a base class with Dog and Cat

Q2. 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.

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