title: variable "using" is a not a type name?
body: <p>I am currently trying to create an application in C as an assignment for school, and my professor requires me to use the following to make it compatible with his compiler: </p>
  
  <pre><code>#pragma warning(disable: 4996)
  #include&lt;string&gt;
  #include&lt;stdlib.h&gt;
  #include&lt;time.h&gt;
  </code></pre>
  
  <p>(I am using visual studio)</p>
  
  <p>And for some reason <code>#include &lt;string&gt;</code> throws up a bunch of run time errors mainly consisting of the one in the title of the question. It pops up within a bunch of other dependencies ranging from cmath, cstudio, cstdlib, cstring, etc. So the bottom line is, can anyone tell me how to fix it? Thanks!</p>
