I'd like to suggest that you get out of the habit of putting multiple statements on one line. That code is pretty messy to read. As you develop larger apps, you need to make sure they're easy to read and debug. Multiple statements on a single line goes against that goal.

Also, avoid single character or meaningless variable names. You know what they mean now, but you won't a year from now and neither will the next guy that has to look at your code.
