将单个位写入文件 [英] Writing single bits to a file

问题描述

我正在开发一个压缩程序。有没有办法以位的形式写一个

数据到文件，比如写0位然后写1位然后

位1等等....

I am developing a compression program. Is there any way to write a
data to file in the form of bits, like write bit 0 then bit 1 and then
bit 1 and so on ....

推荐答案

好吧，如果我只有19个字节要写，那意味着2个字符和3个

比特！

Well, what if I have just 19 bytes to write that means 2 chars and 3
bits!

啊，不。这意味着19个字符和0位。但是你的意思是什么？我

在我的电脑上创建一个1字节的文件，它在我的硬盘上需要4,096字节（另外还有文件名，创建日期等空间）

Ah, no. That means 19 chars and 0 bits. But what''s your point? I
create a 1 byte file on my computer and it take 4,096 bytes on my hard
disk (plus room for file name, creation date, etc.)

我认为你的意思是位，不是字节。这就是为什么

我写的

I think you mean "bits," not "bytes." And that''s why
I wrote

end, you may need to provide a few extra bits to fill
up the final character.

....在你没有引用的部分。我的句子中有什么东西让你感到困惑吗？
