title: Difference between & (ampersand) and && or | (pipe) and || in Objective-C?
body: <p>I wonder if Objective-C does care about whether I write &amp; or &amp;&amp;? I believe one ampersand (&amp;) would or should cause that if the LEFT side is already false, then the right side won't be evaluated.</p>
  
  <p>Does this apply to Objective-C?</p>
