That is, the marginal cost of an additional user is essentially zero for a sizeable number of users, but then marginal cost grows rapidly in the number of users.
这样,在一定人数内,新增一个消费者的边际成本基本为零,但是当使用者达到一定人数后,新增一个消费者的边际成本将非常明显。
So specifying a -m128bit-long-double will align "long double" to a 16-byte boundary by padding the "long double" with an additional 32-bit zero.
因此指定一个- m 128bit - long - double会将“long double”按照16字节边界进行对齐,它会为“long double”填充32位的0。
Now suppose that you want your Data View to include only current products where the units on order equals zero, so that you can decide whether to order additional units.
现假设要数据视图仅包含已订购数量等于零的当前产品,以便决定是否要订购额外数量。
So it does that for us so that you can get away with just knowing the address of the first byte and it will make sure that you know when to stop by including the special value so, in fact, get the string if you type in a three-letter word, we allocate four bytes no matter what because we need an additional byte 0 for this special sentinel value back slash zero at the very end.
它为我们做了这些事情,这样我们就可以,通过第一个字节的地址,它还可以通过包含一个特殊的值,来保证在哪里停止,如果你输入了一个三个字母的单词,就可以获得那个字符串,不管怎样,我们分配四个字节,因为我们在末端需要一个额外的字节,来保存这个特殊的标志值--反斜杠。
