Abstraction is the concept of exposing only the required essential characteristics and behavior with respect to a context.

Real life example of Abstraction in C++

 Example of Abstraction in C++

  1. Consider a real life example of a man driving a car. The man only knows that pressing the accelerators will increase the speed of car or applying brakes will stop the car but he does not know about how on pressing accelerator the speed is actually increasing, he does not know about the inner mechanism of the car or the implementation of accelerator, brakes etc in the car.
  2. Suppose you are operating a mobile phone. You know that the important feature of a phone is the memory card, SIM, battery life, design and build, and processor power. But while operating the phone you do not get into the operational details of the phone such as how the CPU of the phone allocates memory for the various media on your phone or other intricate architectural details of the phone. All these details aren’t visible to cell-phone users from a non-technical background.
