Abstract
Think of an application such as PowerPoint where you can select several different objects and drag them as one. And yet, if you were to select a single object, you can grab that object too. Same goes for rendering: you can render an individual graphic object, or you can group several shapes together and they get drawn as one group.

Notes

There is, of course, no --> operator; it’s quite simply the postfix decrement -- followed by greater than >. The effect, though, is exactly as the --> arrow suggests: in while (count --> 0) we iterate until count reaches zero.
