One of the advantages of this is, that I don't have to worry about explicitly updating my variable. That happens for me automatically.

这样继续下去，这样做的一个优点是,我不用为更新变量来发愁了,程序会自动的为我进行这个操作，这一点很好。

I've decided that I need to be able, in my program, to swap the value of two variables. All right.

我觉定在我的程序中，我可以，交换两个变量值，好的。

But it's a valuable thing. It says, in each case, I return some useful value from this procedure.

但是这就是变量，是在每个例子中，我从这个程序中返回了一些有用的值。

So in fact, it is the case, if you look at data, and by the way, that's the way I ended up setting a lot of these parameters and playing with it, was comparing what my simulation said to historical stock data.

所以实际上，在这个例子中，如果你看到数据，顺便说一下，这就是我设置很多变量,然后编程的方式，也就是把我的仿真程序得到的结果,和历史股票数据进行比较。

We decrement so to speak the variable and then where will we go next in terms of the flow control, the flow of this program.

可以这么说，我们递减这个变量,然后按照控制流，即程序流进入到下一语句。

Right. We're not going to have 140,000 variables in my program.

对的，在我的程序中没有140，000个变量。

So I start this program by declaring as I did before a global variable X. It is global simply because it is not inside any of my functions.

在程序的开始，我声明,一个全局变量X，它是一个全局的,因为它不在任何一个函数里面。

i So I have up here at the top of my program a variable called i 0 of type int, and I have to initialize it up here to zero.

所以在程序的顶端我有一个int类型的变量,我需要把它初始化为。
