Abstraction is one of the most important Object-Oriented Programming principles that confuses many beginners. The idea of abstraction is to show only the most important and essential information while hiding the unimportant and complex details.
There are many examples of abstraction in real life:
- When you drive a car, you don't need to know how the internal components of the car work in order to be able to drive it. All of that complexity is hidden behind simple procedures that make the process of driving a car easier.
The same rule applies in programming. When we make a class that has a lot of functionalities, we can hide the inner details and complex logic related to these functionalities behind a simple interface that will make it easy for other developers to use our class, without having to know how those functionalities are implemented.
In this video, I'm explaining what is abstraction, how to use it, and its purpose in real-life examples and using C++ code as well.
