It's function prototyping.That's needed because `retriver()` is not defined while it's been called.If you remove the prototyping (line 3) you have to use `&retriver()` while calling the function ,which tells the compiler to look for the definition somewhere below.

It isn't needed if you don't use prototypes	[reply]
