x Inside of that structure, create a variable name x, and a value associated with it.

创建了一个变量名为，然后给它赋值，请注意我也在这边做的操作。

And when I create a binding, x I'm taking a variable name, in this case x, stored somewhere in a table, and I'm creating a link or a pointer from that name to that value.

当我创建一个绑定的时候，我有一个变量的名字，在这个例子中是，存在一个表中的某处，然后创建一个连接,或者指针从这个名字指向目标值。

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 have it down that there might be an infinite number of possible values for the random variable x.

对于这个随机变量X,可能的取值个数是无限的

So, what we have found out so far, I'm purposely going from x to y because I want you to know that the unknown variable can be called an x or can be called a y.

到目前为止,我们有这些结论,我特地把x换成y,因为我想让你们明白,未知变量既可以写成x,也可以写成y

Just to remind you what it does, we bound x to some value, we set up an initial variable called ANS or answer, answer and then we run through a little loop.

记住你要做些什么，我们给x赋一个值,我们建立一个初始变量，命名为ANS或者。

What's going on underneath the hood is we'll see pictorially X today is that when I declare this X, this variable X here.

底下所做的，我们将看到,当我声明这个X，这个变量。

And I've got to worry about, is somebody else using ANS, answer, as a variable, in which case I've got to be really careful. Is somebody else using x as a variable? I've got to deal with a lot of those details.

而且我还要担心有没有别人,使用了ANS，answer作为变量,这样我就必须要非常小心,有没有别人用x当做变量呢？,我需要处理很多类似的细节。

But that table does not affect any bindings for other instances of the variable like x for ANS.

这时这个局部表就消失了,这个局部表将不会影响其它赋值,比方说像ANS对应的x变量。

So this line here declares a variable, just storage space called "x" and it's of type "int," which means an integer has to go in it.

这里的这条线声明了一个变量，一个叫做“x“的存储空间，它的类型是“int“,意思是里面存储的是整数型的数据。

What do I have here? I need the variable, ANS, ANS I need x, and I need ANS times ANS, ANS times ANS. Right. Those are the three things that are involved in this computation.

因此让我先用这个方法做吧，我这里需要什么呢？我需要变量，还需要x，然后将ANS乘以ANS，对,在这个计算中涉及到了三件事情。

X So now if we actually introduce the variable X, welcome X. Let's do this again.

现在如果我们引进一个变量，欢迎你，X，让我们再做一次。

Now, unlike high school math or in algebra Z where you call things X and Y and Z, in programming, in computer science, you're actually dealing with humans where it's useful to have a variable name that's more descriptive than X and Y and Z.

不像高中数学或者代数中,称为X和Y和，在程序设计和计算机科学里，你实际上是在和人打交道,在这里有个描述性比xyz更强的,变量名称是很重要的。

The basic definition-- the expected value of some random variable x--E--I guess I should have said that a random variable is a quantity that takes on value.

最基本的定义,某一个随机变量X的期望值E,我应该提到过,随机变量是一个可以取值的数

X So here I'm declaring another variable called X, and this is totally legitimate because I already know that if I'm implementing a function like swap or increment, I can absolutely take input.

这里我声明另一个变量，这个完全是合法的因为我已经知道,如果我执行一个像swap，或，increment的函数，我完全可以携带输入。

Z So it would be incorrect to try to assign this to a variable X or Y or Z, because it doesn't actually give me anything back.

这个是错误的，来赋值这个给变量X或Y或,因为它的确没有返回什么给我。
