Actually sizeof is a unary operator. It applies to the following object, when
object is defined as:
	a variable name
	a variable type (including all struct and pointer types)
	the object of indirection of a pointer type

Examples:
  int ka, kb[10], *kc;
  struct foo sa, *sb;

All the same (part 1):
  sizeof int
  sizeof (int)
  sizeof ka
  sizeof (ka)
  sizeof *kc
  sizeof (*kc)
(however, sizeof kb == 10*sizeof int)

All the same (part 2):
  sizeof struct foo
  sizeof (struct foo)
  sizeof sa
  sizeof (sa)
  sizeof *sb
  sizeof (*sb)
