What is data encapsulation in C++?

Data encapsulation in C++ is a fundamental concept of object-oriented programming that restricts access to certain components of an object.

Can you explain how it works with an example?

Sure! In C++, you can use access specifiers like private, protected, and public to control access to class members. For example, if you have a class 'Car' with a private member 'speed', it can only be accessed through public methods.

What are the benefits of using data encapsulation?

The benefits include improved security, easier maintenance, and better control over how data is accessed and modified.

Are there any drawbacks to data encapsulation?

One potential drawback is that it can lead to more complex code, as you may need to write additional methods to access or modify private data.
