NAME
std::istream_iterator< _Tp, _CharT, _Traits, _Dist > - Provides input
iterator semantics for streams.
SYNOPSIS
#include <iterator>
Inherits std::iterator< _Category, _Tp, _Distance, _Pointer, _Reference
>.
Public Types
typedef _CharT char_type
typedef _Distance difference_type
Distance between iterators is represented as this type.
typedef basic_istream< _CharT, _Traits > istream_type
typedef _Category iterator_category
One of the tag types.
typedef _Pointer pointer
This type represents a pointer-to-value_type.
typedef _Reference reference
This type represents a reference-to-value_type.
typedef _Traits traits_type
typedef _Tp value_type
The type 'pointed to' by the iterator.
Public Member Functions

Friends
bool operator== (const istream_iterator &__x, const istream_iterator
&__y) noexcept
Return true if the iterators refer to the same stream, or are both
at end-of-stream.
