title: error C3861 : identifier not found, error C2065: undeclared identifier
body: <p>I'm new to Visual Studio Express 2008. I succeeded in executing the C++ compiler from command line on my single cpp file, after i had to add some path in the <code>%include%</code> to <code>.. .NET\console\Templates\1033</code> for the <code>stdafx.h</code> definition file (why do i need to do that, i would have thought the installer would put everything i need... ??) and it worked, but now i get the error C3861 for  'printf', 'sprintf', 'fopen'... and also error C2065 for 'FILE', 'fpIndex', 'fpData'... Both errors seem to be associated with a <em>namespace</em> problem! I have no idea on what to do about a namespace, when i tried the command suggested for these errors on MS website <code>using namespace std;</code> i got one more error saying "a namespace with this name does not exist" ?</p>
  
  <p>i only have these few includes and the code</p>
  
  <pre><code>#include "stdafx.h"
  #include &lt;windows.h&gt;
  #include &lt;time.h&gt;
  #include &lt;process.h&gt;
  #include &lt;stdlib.h&gt;
  #include &lt;malloc.h&gt;
  </code></pre>
