In two words, "nothing useful".  It feeds printf two arguments.  The
second is reasonably obvious.  The first is a pointer somewhere into the
string `"%d"'; for example, if `a' were 1, the pointer would point to
the `d'.  This almost certainly isn't what the programmer intended,
although it *is* legal C if `a' is between 0 and 2 inclusive.
