I'm not saying you can't do it that way. I prefer to declare them up top when needed. Variables needed just inside a loop or if get declared at the top, inside.

You may scatter them throughout the code, but that decreases readability, IMO, and then you at least have to search up and down. Well, the more you read the code, the better you know it...
