*output and output have different types, but numberically they are equal.
That's how C works.

More fun:

extern int printf(const char *, ...);

char str[4] = "abc";

int main(void)
{
  int (*f)(const char *, ...) = &printf;
  int (*g)(const char *, ...) = printf;
  char (*p)[4] = &str;
  char *q = str;

  (*f)("%p %p %p %p %p %p\n", &printf, printf, f, *f, g, *g);
  f("%p %p %p %p %p %c\n", &str, str, p, *p, q, *q);

  return 0;
}

It prints:

0x80482d8 0x80482d8 0x80482d8 0x80482d8 0x80482d8 0x80482d8
0x8049624 0x8049624 0x8049624 0x8049624 0x8049624 a
