What is the importance of encapsulation in C++?

Encapsulation is a fundamental concept in C++ that restricts direct access to some of an object's components. It helps in protecting the object's state and ensures that the data is only accessible through well-defined interfaces.

Can you give me an example of encapsulation in C++?

Sure! For instance, consider a class BankAccount that has private data members like balance. You can provide public methods like deposit() and withdraw() to modify the balance, ensuring that it cannot be directly accessed or modified from outside the class.

Why is encapsulation considered a good practice?

Encapsulation is considered good practice because it promotes modularity, enhances code maintainability, and protects the integrity of the data by preventing unintended interference.

What are the other principles of OOP?

The other main principles of Object-Oriented Programming (OOP) are inheritance, polymorphism, and abstraction. Each of these principles contributes to building robust and reusable code.
