The temperature though at two is the same as it was at one, T1 so it's still a temp at T1, and this temperatures is at T2.

Y Why don't I say int temp gets X. Let's say Y oh, sorry, X gets Y and then Y gets temp, this 2 would fail.
为什么我不说明，int，temp，=，X，让我们说明,哦，对不起，X=Y，然后，Y=temp，这两行将失败的。
-
In temp. So that means at the end of that first line of code just as before the value of 1 ends A up in a variable called temp because we said go to A and I look around, oh, there's A, what's there?
在temp中，在第一行代码的末尾,值1最终到了叫做temp的变量中,因为我们指明了定位到,并且四处查看，哦，这里是A，里面是什么？

So A gets 1, B gets 2, now the swap function itself starts executing line by line; so I declare a chunk of memory called temp.
所以A等于1，B等于2，现在swap函数自己开始,一行一行地执行，所以我声明了,叫做temp的一块内存。

foo So everything is literally going back to back to back and so foo, similarly, if you have any local variables, like temp, it then goes here.
所以所有东西都背靠背紧邻着，所以对于，类似的，如果你有任何局部变量，像temp，它前进到这里。
-
Y He's not returning A or B or temp, and definitely not X or Y; so he just did all of this work and yet that's it.

foo Well, if main has any local variables X or Y or temp or foo or bar, or whatever the case may be, those variables come next in memory.
好的，如果main函数有本地的变量X或Y或temp或,或bar，或者诸如此类的例子，这些变量在内存中紧随其后。
-
No. Because A and B and even temp they were by nature local or temporary variables.

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。
