Windows中的EOF [英] EOF in Windows
问题描述
我是C初学者，我正在尝试执行以下代码来自
K& R书：
main（）{
double nc;
for（nc = 0; getchar（）！= EOF; ++ nc ）;
printf（"％0.f\ n"，nc）;
}
我正在运行一个Win2k操作系统，这是一个控制台应用程序。我应该键入什么来获取getchar（）中的EOF值并获取程序
正常终止？在UNIX中是CTRL + D但它不能用于
Win2k。
谢谢，
Mazen
Hi,
I am a C beginner and I am trying to execute the following code from
K&R book:
main() {
double nc;
for(nc =0; getchar() != EOF; ++nc);
printf("%0.f\n", nc);
}
I am running a Win2k OS and this is a console application. What should
I type to get the EOF value in getchar() and get the program to
terminate normally? In UNIX that is CTRL+D but it''s not working with
Win2k.
Thanks,
Mazen

我是C初学者，我正在尝试执行以下代码来自K& R书：
请注意，K& RC是非标准的。我们试着在这里坚持使用标准的
代码（尽管K& R（第2版）仍然是一本强烈推荐的关于C的书）。我建议您使用符合标准的代码，因为我的更正和补充表示
：
#include< stdio.h>
main（ ）{
int main（）
double nc;
for（nc = 0; getchar（）！= EOF; ++ nc）;
printf（"％0.f\ n"，nc）;
返回0;
}

Hi,

K&R book:
Note that K&R C is nonstandard. We try to stick to standard
code here (although K&R (2nd ed) is still a highly recommended
book on C). I suggest you use standard compliant code, as
indicated by my corrections and additions:
#include <stdio.h>
main() {
int main()
double nc;
for(nc =0; getchar() != EOF; ++nc);
printf("%0.f\n", nc);
return 0;

这不是真的在这里，因为它''关于你的
操作系统的问题，而不是C语言。
我没有使用过Win2K，但它的大多数前辈和DOS，其中
EOF用键盘上的CTRL + Z表示。您可能会或可能不会
也需要按Enter键。在CTRL-Z之后。如果这不起作用，
你需要检查你的操作系统文档，或者在Windows
组中询问。

This isn''t really topical here, as it''s a question about your
operating system, and not the C language.
I haven''t used Win2K, but most of its predecessors and DOS, where
EOF is indicated from the keyboard with CTRL+Z. You may or may not
also need to press "Enter" after the CTRL-Z. If that doesn''t work,
you''ll need to check your OS documentation, or ask in a Windows
group.

更好：

printf（"％0.f\ n"，nc）;
添加：
返回0;}

Hi,
I am a C beginner and I am trying to execute the following code from

Add this line:
#include <stdio.h>
main() {
Better:
int main(void) {
double nc;
for(nc =0; getchar() != EOF; ++nc);
printf("%0.f\n", nc);
Add:
return 0;}

您好Mike，
感谢您的帮助。 Ctrl + Z就是诀窍。我正在阅读K& R的第二版
版本，我认为短语ANSI C Compliant在
封面意味着这是标准C，不是吗？
如果你提到一个C初学者的5星级标题，我将不胜感激
开头。请注意，我不是一个初学者，我练习了
C 3年，停了6，现在我回来了agian。所以我真正需要的是快速刷新我的信息。
再次感谢。干杯！

Hi Mike,
Thanks for your help. Ctrl+Z was the trick. I am reading the 2nd
edition of K&R and I thought the phrase "ANSI C Compliant" on the
cover meant that this is standard C, isn''t?
I would appreciate if you mention some 5 stars titles for a C beginner
to start with. Please note that I am not a total beginner, I practiced
C for 3 years, stopped for 6 and now I am back agian. So what I really
need is a fast refresh to my information.
Thanks again. Cheers!
