Question 1

what is a Class

Answer 1

A blueprint or template for creating objects.

Question 2

Object

Answer 2

An actual instance of a class. When you use the blueprint (class), you get a real thing (object).

Question 3

Constructor

Answer 3

A special function that automatically runs when an object is created. It sets initial values.

Question 4

Encapsulation

Answer 4

Wrapping data (variables) and methods (functions) into a single unit (class), and restricting access.

Use private to hide data and public to expose only what’s necessary.

Question 5

5. Inheritance

One class inherits properties and behavior (methods) from another.

Question 6

6. Polymorphism

Answer 6

Same function name, different behavior — depending on context.

Question 7

Hiding complex details and showing only essentials. Achieved using abstract classes or interfaces (in other languages).

Question 8

Answer 8

public: Accessible from anywhere.

private: Only accessible inside the class.

protected: Like private, but accessible in derived classes.

Question 9
