Abstraction in C++ Explained Through a Simple Car Analogy

Abstraction is a programming idea that exposes only the essential features of something while concealing its complicated internal workings. The article illustrates this with a car, where a driver uses the steering wheel, brake, and accelerator without needing to understand the engine. The same principle is applied in C++ to keep code simple for users of a class. A sample Car class demonstrates this, where the public start() method is called from main() and internally triggers the private startEngine() method. Running the program prints the messages confirming that the car starts and the hidden engine process runs.
