I've started thinking about this more after seeing this question.
I'm sometimes tempted to vote such questions as not clear what you're asking, but I also feel that it's not quite needed for this site. This is different from SO, where it's just impossible to help if no request is given with the accompanying code. Here, on the other hand, there's just one main purpose: reviewing code. Of course, the OP could still have specific unspecified requests in mind. Whether or not that's the case, that's not crucial as long as there is code to review.
It could, however, be argued that having no explanation is possibly "another way" to have us review non-working code. Still, that cannot always be assumed in the event that the OP really wasn't aware of any detected issues. That's not what I assume, though. I'm just putting another point out there.
Then again, it could just be laziness... who knows.
Added: I found another example, one that seems "demanding" on top of lazy.
Both questions have something common, though: the code is just "thrown out there" for us to review. The only differences are the tones (if you consider that a factor). While we may still be able to review without context, how do you think visitors merely looking for answers will view them? Without context, it'll hardly benefit anyone but the OP. If it just benefits the OP, then it's of little value to the site (or any SE site).
What do you think?
