Q2. What are classes and objects?
Ans. 
Classes are blueprints for creating objects in object-oriented programming. Objects are instances of classes.
• Classes define the properties and behaviors of objects.

• Objects are instances of classes that can hold data and perform actions.

• Classes can inherit properties and behaviors from other classes.

• Objects can interact with each other by calling methods or accessing properties.

Q3. What is abstract class give real life example of abstraction?
Ans. 
Abstract class is a class that cannot be instantiated and is used as a blueprint for other classes.

Q5. Write code to test a number divisible by 2 or not?
Ans. 
Check if a number is divisible by 2 using modulo operator.
• Use the modulo operator (%) to check if the remainder is 0 when dividing the number by 2.

• If the remainder is 0, then the number is divisible by 2.
