title: How to include header files
body: <p>Does it matter how I import header files? I've seen double quotes as well as arrows used.</p>
  
  <pre><code>#include &lt;stdlib.h&gt;
  #include "Some_Header.h"
  </code></pre>
  
  <p>Does it matter if they're capitalized a certain way as well? Experimenting around with this, it seems neither matters, but I figure there must be a reason for tutorials doing it the way they do.</p>
  
  <p>Another question is, (coming from Java here), how do I access a class outside the file it was defined in? Say, I have one.cpp and two.cpp. </p>
  
  <p>In one.cpp:</p>
  
  <pre><code>class Something {
      ...
  </code></pre>
  
  <p>In two.cpp:</p>
  
  <pre><code>class SomethingElse {
      Something *example;
      ...
  </code></pre>
  
  <p>Like that? In Java you'd just preface a class name with "public." In C++, wrangling classes seems to be a bit more difficult..</p>
