What are some examples of inheritance in C++?

Inheritance in C++ allows a class to inherit properties and methods from another class. For example, if you have a base class Animal and a derived class Dog, the Dog class can inherit attributes like age and methods like speak() from Animal.

Can you show me a code example?

Sure! Here's a simple example:

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

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

int main() {
    Dog myDog;
    myDog.speak(); // Outputs: Dog barks
}

What is the difference between public, protected, and private inheritance?

Public inheritance allows access to base class members as if they were part of the derived class. Protected inheritance restricts access to derived classes only, while private inheritance restricts access to the derived class and its friends only.

Can I inherit multiple classes in C++?

Yes, C++ supports multiple inheritance, allowing a class to inherit from more than one base class. However, it can lead to complexity, such as the diamond problem.
