That didn't work. Well they couldn't figure out what was wrong. And they spent a long time trying to debug the program.

调试这个程序,那时候当然不叫调试了,然后他们发现了问题。

But for the next week or two when you're writing programs, at least for the first time, generally if you're trying Scratch to debug them like you might have been trying to troubleshoot Scratch, you're probably going to reason - through it by looking through the your code -- -- top to bottom, maybe engage a staff member for help -- but your friend will also be printf.

但是，在接下来的一两周内，当你们写程序的时候，或至少在第一次写的时候，通常如果你在调试程序,就像你们可能已经试着调试过,你们或许是通过查看你们的代码,来推断你们的程序-,从头到尾，可能还需要别人的帮忙-,但是你的朋友也将要打印输出。

And I'm hoping that today's lecture will help you learn faster. The nice thing, is once you learn to debug programs, you will discover it's a transferable skill.

但是突然成果就会显现出来,你们现在正在慢慢学着呢，我希望今天的课程能帮助你们学的快一点，好的一方面是，一旦你学会了如何调试程序。

I guess it's not macho enough, John, to just, you know, you know, go off and do things by hand, you ought to just run them, but it's a valuable tool to get into, so let me do that here.

我认为这不太男人了，John，你知道的，他们仅仅是认为比起用手做来,更应该直接去运行程序，但是这确实是调试代码的非常有价值的工具，让我在这里给大家演示下吧。

So I'm going to have an assignment of y, I'm going to have an assignment of iters left, I've got a comment that I had borrowed in order to do some debugging, and then what do I want it to do?

因此我需要对y进行赋值，需要对iters，left进行赋值，还有一个我用的别人的,用来调试的一些注释，那么接下来我希望程序怎么运行呢？
