Inheritance is a mechanism in object-oriented programming where a class inherits properties and behaviors from another class.

- Q3. What is encapsulation

Encapsulation is the concept of bundling data and methods that operate on the data into a single unit, known as a class.

- Q4. What is polymorphism
- Ans.
Polymorphism is the ability of a single function or method to operate on different types of data.
Polymorphism allows objects of different classes to be treated as objects of a common superclass.
There are two types of polymorphism: compile-time (method overloading) and runtime (method overriding).
Example: Animal superclass with Dog and Cat subclasses. Both Dog and Cat can be treated as Animals.
- Q5. What is abstraction
- Ans.
Abstraction is the concept of hiding complex implementation details and showing only the necessary features to the user.
Abstraction allows developers to focus on what an object does rather than how it does it
It helps in reducing complexity and improving code readability
Example: In Java, abstract classes and interfaces are used to achieve abstraction
