title: What is about two conditions in while loop?
body: <p>So, I was looking at a C code, and saw this condition in a while loop:</p>
  
  <pre><code>while(x&amp;&amp;D(x-1),(x/=2)%2&amp;&amp;(1))
  </code></pre>
  
  <p>I searched but only found one with commands, and then condition, and not with <em>two</em> conditions. </p>
