title: namespace "std" has no member "sort"
body: <p>Trying to sort an array of Integers and after some googling, came across the solution using <code>std::sort</code> accompanied by this error: <code>namespace "std" has no member "sort"</code>.</p>
  
  <p>Just to disqalify any qualms that I'm not using the std namespace, here is my header:</p>
  
  <pre><code>#include "stdafx.h"
  #include &lt;iostream&gt;
  #include &lt;fstream&gt;
  #include &lt;sstream&gt;
  #include &lt;string&gt;
  using namespace std;
  </code></pre>
