For example, I have wanted to add whitespaces between operators and digits for a long time. But whenever I try it, it seriously slowed me down. That made me really awful.

For another example, I have a friend Layn. Let's take a look at his code(his recent submission on a Chinese OJ).

We've tried to make him change for a long time. But he didn't change at all.

So I wanted to ask how to improve the style and look of one's code?

(Also, how to make Layn change his code style?)
