| <P><I>Stream iterators</I> are used to access an existing input or output stream using iterators. In the C++ standard, the template classes <B><I><A HREF="../stdlibref/istream-iterator.html">istream_iterator</A></I></B> and <B><I><A HREF="../stdlibref/ostream-iterator.html">ostream_iterator</A></I></B> are referred to as the stream iterators. <B><I>istream_iterator</I></B> reads successive elements from the stream for which it was constructed using the extraction <SAMP>operator>>()</SAMP>; <B><I>ostream_iterator</I></B> writes values to its respective stream using the insertion <SAMP>operator<<()</SAMP>.</P> |
