What is encapsulation and inheritance in C++?

What is encapsulation in C++?

Encapsulation is a fundamental concept in C++ that restricts access to certain components of an object, allowing only specific methods to interact with its data.

Can you give me an example of encapsulation?

Sure! In C++, you can use private variables and public methods to control access. For instance:

class Account {
private:
    double balance;
public:
    void deposit(double amount) {
        balance += amount;
    }
    double getBalance() {
        return balance;
    }
};

What about inheritance? How does it work?

Inheritance allows a class to inherit properties and methods from another class. For example:

class Animal {
public:
    void eat() {}
};
class Dog : public Animal {
public:
    void bark() {}
};

How do encapsulation and inheritance work together?

They work together by allowing derived classes to inherit encapsulated data and methods, promoting code reusability and organization.
