Another famous ancient piece is the "Law Code of Hammurabi, King of Babylon."

And they're awfully simple because, all I can do now, is decide whether to execute some piece of code or another.
它们之所以太简单的原因是:,现在我能做的,就是,决定执行一块代码或者执行另外一块。
OK. All right, let me show you one other tool that I want to use. Which is, I've written that piece of code, I ought to check it. Well, I could just run it, but another useful thing to do is, I'm, especially as I want to debug these things, is to simulate that code.
好,那么,让我给大家讲下,我想用的另外一个工具吧,也就是,我已经写好了这一块代码,我应该去检查检查,那么我可以去运行它,但是特别是当我想要调试代码的时候。
stdio h This file here is called standard I/O or stdio.h and this is just another text file someone else wrote many years ago and by using that line of code there, I'm telling the computer, give me acces to this code that this other person wrote that's in that file.
在这里的头文件称为标准输入输出文件或,这是由某位前人编写的文本文件,我们只需要刚才所述的一行代码,就能告诉电脑,让我连接到,这个前人在那个文件中写的代码。
So this first little piece of code right here says, ok you give me 2 points, I'll create another 1 of these lists and I'll simply take the x, sorry I shouldn't say x, I'm going to assume it's the x, the x-values are the two points, add them together, just right there, the y-values, add them together and return that list.
好,为了来认识到这一点,让我们来看一个简单的小例子,在你们的课堂手册上,你可以看到我写了一个小程序,它假设我得到了,这些点中的一些,我想对它们做一些操作,例如我想把它们加到一起,那么这里的第一小片,代码的意思是,好给我两个点,我会再创建一个数组。
OK, so how can I code this up? Well, you might think, let's just jump in and write some code, I don't want to quite do that though, because I want to show you another tool that's valuable for thinking about how to structure the code, and that is a something called a flow chart. Now.
好,那么我怎么把这个以代码实现呢,你可能会想,让我们进去直接写代码把,但是我不想这么做,因为我想教给大家另外一项很有价值的,用来组织代码的工具,叫做流程图,现在,像Guttag教授,和我这么大岁数的人。
