It turns out that slightly before the stack, slightly before this conceptual chunk of memory, there's other things called environment variables that we may see over time but elsewhere in memory are other things.

结果是稍微在堆之前，稍微在这个内存块概念之前，另外还一个东西叫做环境变量,我们之后可能看到，内存中的其他地方,是其他的东西。

I have no idea what's here at the moment so I'm just going to draw a question mark because that memory might have been used previously for some other purpose, but we know it's currently available to us so we have four bytes of memory.

我不知道在此刻这里是什么,所以我画一个问号，因为那块内存可能在之前,为其它的目的而使用过，但是我们知道它可以为我们所使用,这样我们就有4个字节的内存。

Which may take up some arbitrary amount of memory. In that case, I'm back to this problem.

然后将接下来的每一个内存块设置为,指向数组对应元素值的指针。

Well, if that function calls another function, you put another tray on, and so that new tray represents that function's chunk of memory.

好的，如果那个函数调用另一个函数，你再放一个托盘在上面，新的托盘代表,那个函数的内存块。

And this would point to value, and this would point off someplace in memory.

需要多少个基本内存块，然后我就得知下一个元素的位置了。

It's reasonable because it's meant TMP for temporary purposes just to call it temp or T-M-P for short, X and I can define temp as -- why don't I set it as equal to X, initially, because now that I've stored X in a separate chunk of memory, I can now change its value and then I can say Y gets, not X, but temp, and so now I've actually swapped these values.

这是合理的，因为它是为,暂时的目的，只要叫它Temp或简称它为，我可以定义temp为--为什么我不把它设定为等于，最初的，因为现在我把X存储在一个单独的内存块中,我现在可以改变它的值，然后我说Y等于，不是X，而是temp，所以现在我交换这些值。
