As others have said, f is a two-element array.  C arrays start at zero,
so the only valid elements in f are f[0] and f[1].  If you want to have
three elements in f, declare f as f[3].

Unless things have gone horribly wrong, this program should only return
zero.

Did you mean that the program prints (instead of returns) 7 or 6?
