If that blows your mind, you might want to avoid looking at the following: "foo"[2] == ("foo"+2) == (2+"foo") == 2["foo"]. And yes, you really can do that: in general a[b] and b[a] are exactly the same thing in C.

More C array pointer fun:

  *("abcdefg" + 3) == 'd'

sure as long as you don't care about stuff like unicode..

not quite. "foo"[2] is a char, ("foo"+2) is a string.

oh, bother, I forgot what HN does to asterisks. In what I wrote above, look for the bit in italics and mentally insert asterisks on each side of it. It was right when I typed it in, I promise...
