There's a whole bunch of blocks that we'll look at in more fun detail on Friday but I'm going to pick the easiest one here and I'm going to type Hello CS50 in this string, "Hello CS50", zooming in say how nice the puzzle pieces are nicely interlocked?

今天我们看到的各种图块,到下周五我会仔细讲解其中的精妙之处,但今天我只想举一个最简单的例子,我要在这儿键入字符串，放大窗口，然后看看这漂亮的图形和文字,是如何美妙地连结在一起的？

So that way you can have an idea if, oh, I do really understand this but I'm a little bit slow, maybe I need to practice this one type of problem a little bit longer so I can get up to speed so I'm going to be able to get through all this in terms of the exam time.

这样你就可以知道，假设，噢，我真的懂这个，但是我的速度有点慢，或许我需要在练习这个类型的题目上,多花一点时间,这样我就可以提高自己的速度,可以全部做完,在考试规定的时间内。

OK, now, if I actually do this, and I'm going to show you the example, I just, what did I type over there, I got p was a c point.

传入了其他的参数，好，现在，如果我，实际上要做这个的话，我要给大家看个例子。

The format is the same. I'm going to ask for some input, and then I am going to use that procedure to check, is this the right type of value. And I'm trying to use that to do the coercion if you like. Same thing if it works, I'm going to skip that, if it not, it's going to throw the exception.

格式是一样的，我需要一些输入,然后我要用一个过程来检查,是否是正确的值,然后你就可以做强制转换了,如果能运行，那是一样的，我打算跳过这段，如果不正确，那就会抛出一个异常。

So, summarizing better, assert is something you put in to say to the user, make sure you're giving me input of this type, but I'm going to guarantee you the rest of the code works correctly. Exceptions and exception handlers are saying, here are the odd cases that I might see and here's what I'd like to do in those cases in order to try and be able to deal with them.

所以更好的总结下,断言就是你放在那里告诉用户,保证你输入的是这种类型的,但我能保证剩下的代码运行正确,异常和异常处理做的事,这里有些我能预期的异常情况,并且这里有些情况,我能尝试处理。

So I'm going to go over here, and I'm going to type test search-- I can type and if you look at your handout, it's just a sequence of tests that I'm going to do OK. So initially, I'm going to set up the list to be the first million integers.

大家可以看看你们的课堂材料，那儿有一些我要做的实验,好，一开始我先去建立个，含有一百万个integer的数组,对，这有点儿简单,但是这给我提供了这样一个有序的数组。

And then I run a loop in which I read something in, I check to see if it's the right type, if it is, I change that variable to say it's now the correct type, which means the next time through the loop, I'm going to say I'm all set and I'm going to bounce out.

因为我还没输入，然后我运行一个循环,循环内部我输入一些东西,然后看看是不是正确的类型,如果是的话我改变input，Ok为真，来证明输入数是正确的类型，这就意味着下一次运行这个循环的时候,就可以跳出循环继续执行了。
