title: How to get an element at specified index from c++ List
body: <p>I have a <code>list</code>:</p>
  
  <pre><code>list&lt;Student&gt;* l;
  </code></pre>
  
  <p>and I would like to get an element at a specified index. Example:</p>
  
  <pre><code>l-&gt;get(4)//getting 4th element
  </code></pre>
  
  <p>Is there a function or method in <code>list</code>  which enables it to do so?</p>
