I'm thinking about a problem, I'm going to show you an example in a second, first thing I'm going to do is say, what is the thing that's going to change every time I run through the same set of code?

我要解决一个问题，我马上会让大家看一个例子，第一件我要做的事情就是,弄明白每次运行同样的指令集时,每次都会改变的东西是什么？

And I want to remind you, that block of code is a set of instructions, the same set of instructions that are going to be done each time through the loop.

我想提醒大家,这块代码是一个指令集,一个每次循环都会被执行的相同指令集,会变化的仅仅是变量的值。

Now you have a set of parentheses as we'll see int i=0 in actual code and then I have int I equal 0.

你将会在实际的代码中看到一对圆括号,比如，我们让。

And for a couple of reasons, one this is the first P set where we're actually gonna give you code to work from.

由于一些原因，这里是第一个习题集,在此我们提供了一些代码供大家参考。

This little set of code here from create insert and number. What's create do?

这一小段代码是创建插入和编号的,创建是做什么的？

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 stress it in particular because I know you're all going to get into this stage; you've got a problem set due in a couple of hours, you're still writing the code, you don't want to waste time, and I'm going to use quotes on "waste time", doing those extra things to do the defensive programming, you just want to get the darn thing done.

我特别强调了这一点,因为我知道你们都会慢慢成为程序员;,你在写代码过程中造成了一系列的错误，你还在写代码，你不想浪费时间，我想把“浪费时间“用引号圈起来，浪费时间来做因为防卫性程序设计，而带来的这些额外的事情,你只想赶紧把程序写完，这不是一个好习惯，因为当你做完回头。

And that shows you one other nice little thing we want to do, which is if I look in this code notice I set up a variable up here called false Solution Found, initially bound to false.

这显示了我们想要做的另一件事,那就是我在这段代码中设置了一个,名为Solution，Found的变量,初始值设为。

But here, if I decide I'm going to store things not in x and y, but with some other set of names, for example, I've gotta go back into these pieces of code that use the points, and change them. So I've lost modularity.

除了要改下借口,但是这里，如果我决定，我不把值放在x和y中，而是和其他一些变量名进行绑定,例如这样的话,我就得回到使用这个点的代码，那儿去做更改了。
