So this we would want to delete in order for the code not to run the risk of crashing, but let's now see this was made by an excellent teacher out at Stanford University.

我要按顺序删除它，不要冒崩溃的风险,但是这个是由一个来自斯坦福大学的,优秀教师做的。

OK. Let's simulate the code. Let's see what it's doing here. All right, so we start off.

让我们看看这里到底做了神马？,好的，我们开始吧。

And when I'm starting to write lots of lines of code, you know, it's frankly kind of useful to be able to see more on the screen at once without having to scroll.

当我开始写很多行代码的时候，你们懂的，这明显是有用的，当你可以在屏幕上看到更多的代码,而不用滚动屏幕。

Because what you don't see in this file is any code a that actually says put a letter of the alphabet at the top left hand corner of the screen and then put the next character to the right in other words, I'm taking for granted at this moment in time that my computer knows how to print something to the screen.

就是这些你在本文件中看不到的一些代码,实现了将首字母,放在屏幕的左上角,然后把其他字母加在其右边，我想当然地认为,我的电脑知道如何打印相应信息到屏幕上。

Spelling. These are just dumb little things to look for. Did you spell all the identifiers the way you think you did. The problem is, when you read code you see what you expect to see.

拼写错误，你可能得找找这些粗心的小错误,你是否拼对了标识符,问题是当你阅读代码的时候,你看到的都是你以为的。

All right. If you flip to the second side of your handout, you'll see that I have a piece of code there, that does this-- let me, ah, I didn't want to do that, let me back up slightly- this is the algorithm called search.

你可以看到实现这个功能的代码,让我，额，我不想这么做,让我们回来一点,这就是命名为search的算法-,我们来看看这个算法吧。

cs50 h It's not called standard io.h, it's called cs50.h. That's where the code we wrote for you will live and then we'll see how to do this in examples today onward but we wrote for you some tools, some functions that calls GetChar for get a character.

当然不是标准输入输出库了，而是叫做,这里面有一些我们写的代码,等一下我会举几个例子,我们写了一些函数,比如GetChar，意思是得到一个变量。

Now, the one that we're most interested in ANS is the one where, in fact, it gets out ANS, so you see down here in the code, there's a spot where it's going to return the value of ANS, which is what we want, right? That's the thing that holds the value that we intended to have.

现在我们最感兴趣的是这个,事实上它返回的是，所以你看这段代码,在这里返回ANS值,也就是我们想要的,对吧？,它就承载了我们想得到的值。
