/*
In the following code coming from "The C Programming Language" of Kernighan and Ritchie,

we have an interesting insight, obvious, but still interesting to remind : even if the parameter s is not declared as a reference,
as it is allowed to be in C++, it acts as a reference. Indeed, what is behind an array in C Programming language, is a pointer.
