嗯,再次强调,就像我刚才说的,如果你从这里出发,你将依次接触到,试着读取或者改变内存,如果超出了你可以使用的,内存块长度的界限。

So conceptually the key difference here, besides the syntax looking slightly different, it just means that if you want a chunk of code to execute no matter what initially, ; you can use the do while loop; if you want to check a condition first, you can use the while loop.

Unsurprisingly, you've got the ability to do decent work in this class and most of you have the ability to do good work, and some of you have, a fair chunk of you have, the ability to do excellent work, though it may take some work on your part to get to that point.

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.

So, certainly the CS50 Library designed to be dynamic and, in fact, any time you call get string, we are, in fact, ; allocating a chunk of RAM but it's not coming from the stack; it's actually coming from this portion of memory called the heap.
所以,Cs50库是动态设计的,实际上,每次你调用GetSting时,我们分配一块内存,但它不是来自栈;,而是来自于叫做堆的,内存的一部分。
So that means if you-- whether you own a Mac, PC or whatever, you have a whole chunk of RAM memory which you can draw for instance as a rectangle, if you can't quite see.
也就是说,无论你的电脑是Mac也好,PC也好或其他什么的,你会有厚厚一块RAM存储器,我们可以把它画成长方形,你们有可能看不到。
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。
