Explore OOP in C++ to write cleaner, modular, and scalable code. Learn classes in C++, data hiding, encapsulation, abstraction, inheritance, and polymorphism in C++.

Become  a C++ Programmer

This module aims to teach us how to write cleaner, more modular, and scalable code in C++ by providing an understanding of OOP in C++. We'll start with the basics of object-oriented programming and build up to advanced concepts such as inheritance, data hiding, and polymorphism. Along the way, we'll explore how each concept applies to C++ and how various C++ features facilitate OOP.

Object-Oriented Programming in C++

# Historical Background

It was in the `60’s` and early `70’s` when the idea of **object-oriented** programming started occupying the minds of programmers. Keeping in view the benefits acquired through object orientation in SIMULA, the scientists encouraged languages using the same approach for programming. **Object-oriented** programming was a complete paradigm shift from the popular structural programming. 

# Object: A Fundamental Entity

**Object-oriented** programming is based on the idea of an `object`. An `object` is an entity with some *data* and *operations*. Data is also referred to as *properties* of the object whereas operations include accessing and modifying those properties along with other functions that depict the behavior of the object.

## Example

A **fork** is an object with properties including a number of *prongs*, its *size*, and *material* (made of plastic or metal), etc. Behavior and functions of a fork include shredding, squashing, making design or may be simply eating.





In this lesson, we'll learn about the historical background of OOP and also key features of object-oriented programming.
