Adding a score and a message
Now we know enough about strings, SFML Text, and SFML Font to go about implementing the HUD.
The next thing we need to do is to add another #include directive to the top of the code file. As we have learned, the sstream class adds some really useful functionality for combining strings, and other variable types, together into a string.
Add the following line of highlighted code:
#include "stdafx.h"
#include <sstream>
#include <SFML/Graphics.hpp>
