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。

It's just a little block of memory in RAM, you know, that represents four bytes, 32-bits and the Number Two is currently in it.

它只是一小块内存块，它表示4个字节，32位,那个数字2就存储在里面。

They might very well be storing the addresses of memory elsewhere, but we just needed them as sort of a cheat sheet, a little address card to know where the original values x and y were.

它们存储在内存的其他地方是可以的,但是我们需要一个备忘单,一个地址卡，来知道,原始的值x和y是什么。

Well, int is almost always 32 bits at least so far as we've seen so, in fact, any time I draw a pointer hence force I'm just going to draw a square as well because they are, in fact, the same size usually in memory.

嗯，int几乎总是32位的,至少我们至今所看到的是这样的，每次我用一个正方形表示一个指针,因为实际上他们，在内存中的大小是一样的。
