What does <- mean in C++?
<p>I was looking around for something else when I stumbled upon <a href="http://stackoverflow.com/questions/8831221/looking-for-a-more-efficient-ifelse">this article</a>.  I looked at it blankly.  I didn't have any idea how to parse it.</p>

<p>Could someone please explain or point me in the right direction?</p>
