What is encapsulation in C++?

Encapsulation is a fundamental concept in C++ that restricts access to certain components of an object. It allows you to bundle data and methods that operate on that data within a single unit, typically a class.

Can you give me an example of encapsulation?

Sure! Here's a simple example:

class Car {
private:
    int speed;
public:
    void setSpeed(int s) {
        speed = s;
    }
    int getSpeed() {
        return speed;
    }
};

In this example, the speed variable is private, and can only be accessed through the public methods setSpeed and getSpeed.

Why is encapsulation important?

Encapsulation is important because it helps protect the internal state of an object from unintended interference and misuse. It also promotes modularity and maintainability in code.

What are the benefits of using encapsulation?

The benefits include improved code security, easier debugging, and the ability to change the internal implementation without affecting external code that uses the class.
