关于fputs的问题（） [英] A question about fputs()
问题描述
为什么没有fputs（）在将空终止字符串
写入流时写入空字节？我没有看到这背后的原因。
Chad
Why doesn''t fputs() write the null byte when the null-terminted string
is written to a stream? I don''t see the reasoning behind this.

也许您可以解释为什么您认为像fputs这样的面向文本的函数
应该关注非文本导向的值，例如作为一个空字节？
我没看到背后的原因/那个/。

Perhaps you could explain why you think a text-oriented function like fputs
should concern itself with a non-text-oriented value such as a null byte?
I don''t see the reasoning behind /that/.

让我们说我有一个字符串如下
"这是一个字符串\ n"
如果puts删除，这不会产生未定义的行为'\ n''？
Let''s say I have a string like the following
"This is a string\n"
Wouldn''t this create undefined behavior if puts removes ''\n''?

或许你可以解释为什么你认为像文件导向的函数像
fputs应该关注非文本导向的值，例如
null字节？我没有看到背后的原因/那个/。

让我们说我有一个像下面这样的字符串
"这是一个字符串\ n"
如果puts删除''\ n''，这不会产生未定义的行为吗？

"This is a string\n"
Wouldn''t this create undefined behavior if puts removes ''\n''?
我可以更进一步，并说它会向后打印
如果将打印的东西向后推出。但是看跌期权并没有这样做 - 而且它还没有删除新行。
也没有删除换行符。文本是一种面向行的格式，并且新行定义了一行
（只要换行符出现在每行
行的末尾）。 puts函数是一个面向文本的函数，如果它删除了换行符，它确实是一个非常奇怪的鸟。我没有看到你想要赚的钱。如果你试图在null
字节和换行符之间进行比较，它就不起作用 - 换行符是
文本流的基本部分，而null字节是没有。

I can go further than that, and say that it would be printed out backwards
if puts printed stuff out backwards. But puts doesn''t do that - and it
doesn''t remove newlines either. Text is a line-oriented format, and a line
is defined by newlines (insofar as a newline appears at the end of every
line). The puts function, which is a text-oriented function, would be a
very strange bird indeed if it removed newlines. I don''t see the point you
are trying to make. If you are trying to draw a comparison between null
bytes and newlines, it doesn''t work - newlines are a fundamental part of
text streams, whereas null bytes are not.
