Because as you'll soon find, when you're writing programs 0 that aren't just four lines long but are 40 or 400 which very quickly becomes easy, you'll find that even you the next morning have no idea what this code does for whatever reason, and just having some English comments is a huge boon to comprehension for yourself and others.

你们自己写程序时就会发现,用40行甚至400行代码来代替繁杂拥挤的4行代码0,将会让事情简化许多，你会发现，即使由于某些原因,你不知道如何写代码，先写些注释，于人于己，都是好事,易于理解嘛。

那么再然我们看一看,一些有用的东西,这是compare1。c，所以在compare1。c中，在我的版本中,我吧注释去掉了,但是在你们的版本中是有注释的,这是相当容易理解的,如果你通读这段代码。
