title: Precompiled Header Syntax
body: <p>I recently discovered the concept of using a precompiled header within a large project, to speed up compile time for those system headers that do not change.</p>
  
  <p>I am now attempting to add to my own project, my question, is this the correct syntax ? or is there something more i have to add, for it to be marked and recognized as a pch.h ?  thanks</p>
  
  <pre><code>#ifndef PCH_H_INCLUDED
  #define PCH_H_INCLUDED
  
  #include &lt;iostream&gt;
  #include &lt;fstream&gt;
  #include &lt;sstream&gt;
  #include &lt;strstream&gt;
  #include &lt;chrono&gt;
  #include &lt;random&gt;
  #include &lt;ctime&gt;
  #include &lt;memory&gt;
  #include &lt;iterator&gt;
