title: Two pointers comparison
body: <pre><code>pf1==pf2    pf1 and pf2 point to the same array element
  
  pf1&gt;pf2     pf1 is the higher address location
  
  pf1&lt;pf2     pf2 is the lower  address location
  </code></pre>
  
  <p>I want to know if the third sentence should be：<code>pf2 is the higher address location</code>？</p>
