Usages of stream iterators?
<p>I have been looking at ostream and istream iterators and wondering how much used they are in the real world.  I have looked at a couple of books and a lot of web pages and everything is always a variation of the same example like</p>

<pre><code>  ostream_iterator&lt;int&gt; out_it (cout,", ");
  copy(myvector.begin(), myvector.end(), out_it);
</code></pre>

<p>Can these stream iterators be used with real files and binary data and is that normally done?</p>
