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。
Yup. So m sub l could equal 2 negative 2, negative 1, 0, 1 or 2.

否则如果n大于4,并且n小于-,我们叫它为中间数--否则如果n大于等于,小于等于10--我们叫它为“大数“,如果用户键入了0或者-10或20或其它的,让我们用一个广泛的else子句,只需要说,“你选了一个非法的数字“
