++dthacker, for saying what I would have said had I been paying attention. :)
A few notes I'd like to chime in: Usually, with any question, there are three kinds of right answers. There's the right answer that shows how but not why, the right answer that shows why but not how, and the right answer that shows how and why.
That is, for question A, there is
- "This is what you want to do instead."
- "That's the wrong method you're using."
- "That causes this kind of problem. Here's how to avoid it."
It's easy to look at the three and guess which is the most informative; it's the last, which tells you how and why. I've found that often times one is left out of instruction to the detriment of the reader, who then is left to figure out "When do I use this?" or "But what does that look like in code?" with some other manual/tutorial/explanation.
From this beginner, please, if you see something I'm doing wrong, don't hesitate to correct me and explain it at the same time. I'm here to learn, and, hopefully, one day teach.
