/* Emits a 7-Hz tone for 10 seconds.
  True story: 7 Hz is the resonant frequency of a
  chicken's skull cavity. This was determined
  empirically in Australia, where a new factory
  generating 7-Hz tones was located too close to a
  chicken ranch: When the factory started up, all the
  chickens died.
  Your PC may not be able to emit a 7-Hz tone. */

    sound(7);

    nosound();

// TODO: Implement this function!

-- Change Log:  Not needed. The code is perfect 'cause I wrote it.
-- If you change it, it will break.

我正在检查一些代码注释，以检查它们是否有意义，并看到上面的一行。

在给一个朋友看了这篇来自《Coding Horror》的文章几个小时后，我看到了他对代码的评论:

// valdez先生是一个暴力的精神病患者。别惹他生气。

long time; /* just seems that way */

// If this comment is removed the program will blow up
