What is the difference between encapsulation and inheritance in C++?

Encapsulation is the bundling of data and methods that operate on that data within a single unit, like a class. Inheritance, on the other hand, allows a class to inherit properties and behaviors from another class, promoting code reusability.

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

Sure! In C++, encapsulation can be demonstrated with a class that has private data members and public methods to access them. For example:

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

What about inheritance? Can you show me an example?

Absolutely! Here's a simple example of inheritance:

class Animal {
public:
    void speak() {
        cout << "Animal speaks";
    }
};

class Dog : public Animal {
public:
    void speak() {
        cout << "Dog barks";
    }
};

How do encapsulation and inheritance work together in C++?

They work together by allowing you to create a base class with encapsulated data and methods, and then derive subclasses that inherit those properties while also adding their own specific behaviors.
