For  example:</p>  <pre class="example-code">  stream1 << "hello" << i;</pre>  <p>This example inserts the string "hello" and the variable <i>i</i>  into <i>stream1</i>.  In contrast, the &gt;&gt; operator extracts  data out of a string stream:</p>  <pre class="example-code">  stream1 >> i;</pre>  <p>This code reads a value from <i>stream1</i> and assigns the  variable <i>i</i> that value.</p>  <div class="related-name-format">    Related topics:  </div>  <div class="related-content">    <a href="../cppio/index.html">C++ I/O Streams</a><br>  </div>  </div>  </td>    </tr>  </table></body></html>
