(Speaking) At an office computer and Internet skills class at Byte Back, a non-profit organization in Washington, Before enrolling in the class.

VOA: standard.2010.01.05

And because there are a billion bytes accessible to us, that's-- essentially means well we can just call that byte number zero.

由于有十亿个字节的存储量供我们使用-,也就是说，我们有0号字节。

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。

This is convention, so on almost-- and most any computer you overuse, if you're writing code that uses a char, you're gonna be handed 8 bits or 1 byte to store that particular char.

这是约定，对于大多数-,电脑，当你写代码要用到一个char型数据时,必须先预留8比特或1字节,的空间来存储这个char型数据。

D-A-V-I-D So when you get a string like D-A-V-I-D, what's really happening is inside your computer's RAM is going a byte where there's some zeros and ones.

譬如你有这么一个字符串，而在你电脑的RAM里将会变成,一个个由0和1组成的字节。

So a char is one byte, which is bits -- how many?

所以char类型占了1个字节，--那是多少位？
