Stream states:
  *if (s): The previous operation was successful (a shorthand for !s.fail()).
  *if (s.fail()): The previous operation failed.
  *if (s.eof()): Reading past the end has been attempted.
  *if (s.bad()): Stream state is undefined; the stream can no longer be used.
  *if (s.good()): None of bad/eof/fail are set.
