What are C++ classes and how do I use them?

C++ classes are blueprints for creating objects. They encapsulate data and functions that operate on that data.

Can you give me an example of a simple class?

Sure! Here's a simple class definition:

class Dog {
public:
    void bark() {
        std::cout << "Woof!";
    }
};

This class has a method bark that outputs "Woof!".

How do I create an object from this class?

You can create an object like this:

Dog myDog;
myDog.bark();

This creates an instance of the Dog class and calls the bark method.

What are constructors and destructors in C++?

Constructors are special functions that initialize objects, while destructors clean up when an object is no longer needed.
