Question 15

Write a short note on the principles of Object Oriented Programming.

Answer

There are four principles of Object Oriented Programming:

  1. Data Abstraction — It refers to the act of representing essential features without including the background details.
  2. Encapsulation — It is a mechanism that binds the data and code (functions) together into a single unit.
  3. Inheritance — It is a powerful mechanism by which one class acquires the properties of another class.
  4. Polymorphism — It is the ability of a function or object to take on multiple forms.
