What are some real-world examples of encapsulation in C++?

Encapsulation in C++ is about bundling data and methods that operate on that data within a class. A real-world example is a class representing a bank account, where the balance is private and can only be modified through public methods like deposit and withdraw.

Can you explain how this helps in programming?

Sure! Encapsulation helps in protecting the internal state of an object from unintended interference and misuse. It allows for controlled access to the data, which enhances security and maintainability.

Are there any other examples besides bank accounts?

Yes, another example is a car class. The car's speed and fuel level can be private, and you can have public methods like accelerate and refuel to interact with those properties.

How does encapsulation relate to data hiding?

Encapsulation is a key principle of data hiding. By restricting access to the internal state of an object, encapsulation ensures that the object's data can only be changed in controlled ways, thus promoting data integrity.
