bool operator!= (const istream_iterator &__x, const istream_iterator &__y)
Return true if the iterators refer to different streams, or if one is at end-of-stream and the other is not. bool operator== (const istream_iterator &__x, const istream_iterator &__y)
Return true if the iterators refer to the same stream, or are both at end-of-stream.
