Object-oriented programming (OOP) has been around for decades. If you have a basic understanding of C++ and are interested in leveling up your skills, this class will help you do just that. 

Starting with an overview of the basics, you’ll dive into understanding the time-honored technique for implementing complex applications using user-defined classes. Followed up by discussing classes and objects, and then building up to the high-level topics including inheritance and polymorphism. 

Throughout the course, you’ll be fully immersed in OOP for C++, with illustrations, exercises, quizzes, and hands-on challenges every step of the way. You’ll walk away with an understanding of classes and objects behavior and be able to easily create simple, efficient, reusable and secure code.

Learn 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.





### Explanation

Programmers realized that when we represent entities in the program as objects, having their behaviors and properties, it becomes easy to deal with the increasing code complexity as well as the code becomes more reusable. So, a *fork* object can be part of a dinner set, and a similar object may also be sold separately. Once, we know its properties and behavior, we only need to reuse the same piece of code whenever a *fork* is needed.
