Creating windows
The first thing you would probably want to do when you start developing a game is open a
window. In SFML, this couldn't have been made any easier. Only one line of code is neces-
sary to create a window:

The only thing that the main function does is initialize the window variable by calling the
sf::Window constructor, after which the program exits. There is an alternative way to
open a window by using the default constructor and calling Window::create() later
on. This function takes exactly the same arguments as the constructor, which we just went
through. If Window::create() is called on a window, which is already open, it closes
the window and reinitializes it with the new set of parameters.
In the example given in the preceding screenshot, notice that both Window and
VideoMode are in the sf namespace. Every class in SFML is under that namespace,
which separates all the classes in SFML from the classes in other libraries.
If we run the code in the example, we won't see much. The program exits immediately after
it creates the window. That is because we just create a window without doing anything with
