How do I use classes in C++?

In C++, classes are used to create user-defined data types. 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!" << std::endl;
    }
};

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

How do I create an object of this class?

You can create an object of the class like this:

Dog myDog;
myDog.bark();

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

What if I want to add attributes to the class?

You can add attributes by declaring member variables inside the class. For example:

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