title: What's the difference between cstdlib and stdlib.h?
body: <p>When writing C++ code is there any difference between:</p>
  
  <pre><code>#include &lt;cstdlib&gt;
  </code></pre>
  
  <p>and</p>
  
  <pre><code>#include &lt;stdlib.h&gt;
  </code></pre>
  
  <p>other than the former being mostly contained within the <code>std::</code> namespace?</p>
  
  <p>Is there any reason other than coding standards and style to use one over the other?</p>
