# Classes in C++

A class groups data and behavior together.

```cpp

#include <iostream>

#include <string>

class Greeter

{

public:

explicit Greeter(std::string name)

: name_(std::move(name))

{

}

void say_hello() const

{

std::cout << "Hello, " << name_ << std::endl;

}

private:

std::string name_;

};

int main()

{

Greeter greeter("Vix Note");

greeter.say_hello();

return 0;

}

```

Classes are useful when data and behavior should live together.
