In fact, this example would compile because you can use curly braces in this way to encapsulate lines of code, but realize for now, that, not good.

I will tell you that a good programmer, at least in my mind, may actually go back and modify the pseudo code as they realize they're missing things, but it's easier to do that when you're looking at a simple set of steps, than when you're in the middle of a pile of code.
至少我认为是这样的，如果他们发现遗漏了,一些步骤的话会,回过头去修改伪代码,但这当你面对一些大致的步骤时,这个过程就会比,面对一堆代码要简单的多。

I've certainly written code that has this problem, I've tried to use my own code that has this problem, and good to us, right, good hygiene, I'm going to use that word again here, of getting into the habit of writing defensive code up front, it's part of that collection of things that you ought to do is a great thing to do.
我举手了吧？,我当然写过犯这种错误的程序了,我也尝试过应用含有这种错误的代码，不错，好的卫生，我还是要用这个词,对我们有帮助，养成写防卫性,代码的好习惯，是你应该做的,一系列事情之一,也是我们日后要做的主要的事情。

OK. Note, by the way, if I chase through each possible path, like there's some IFs in here, if there's some places to go, at least in this piece of code, every possible path through this code ends in a return. And that's a good programming discipline, to make sure that happens.
注意一下,如果我跟进每一条可能的路径，像是这里的，起码在这段代码中就有很多走向，这段代码中的每一条可能路径,在结尾都会返回一个值,这就是一条很好的编程定律，请确保这样做。
