Why does the call char scanf work?

Q

Why does the call
char s[30];
scanf("%s", s);

work? I thought you always needed an & on each variable passed to scanf.

You always need a pointer; you don't necessarily need an explicit &. When you pass an array to scanf, you do not need the &, because arrays are always passed to functions as pointers, whether you use & or not.
