出 [英] out
问题描述
#include< stdio.h>
int out（int n，char * buffer）{
if（n =（int）NULL ）{
返回看跌期权（缓冲区）;
}
如果（n = 1）{
返回fputs （buffer，stdout）;
}
if（n！= 1 || n！=（int）NULL）{
fprintf（ stderr，用法错误\ n）;
返回0;
}
}
上面的代码之前我添加了int casts只是一个直觉，并没有
工作。通过在NULL之前添加int转换，我真的做了什么？
我希望写的是正确的。 int之前的代码将编译后的b / b
编译成目标文件，但编译器通过bash'的stderr给了我警告
我需要演员。我是否纠正了可移植性问题。即使它是正确的，也要知道你做了什么，这是不好的。

正如我之前所说的，这个Bill Cunningham是一个巨魔。
然而很多人都不理我并继续回应.. 。
无论是巨魔还是完全无法学习该语言。这是一个完美的浪费时间来尝试对话。

0，不便携？ 1或2怎么样？

我们不会忽视你，我们只是不同意。我不相信他是故意的巨魔。他说他有某种学习障碍
但是他正试图学习C语言。我没有理由让b $ b不相信他。
他自2002年以来一直在学习C语言，并且没有比这更进一步的b
进步。如果他不是巨魔，那么每个人都需要意识到这不会发生。

#include <stdio.h>
int out(int n, char *buffer) {
if (n=(int)NULL) {
return puts(buffer);
}
if (n=1) {
return fputs(buffer,stdout);
}
if(n!=1||n!=(int)NULL) {
fprintf(stderr,"Usage error\n");
return 0;
}
}
The above code before I added the int casts just by a gut feeling didn''t
work. By adding the int casts in front of the NULLs what have I really done?
I hope the wrote the right thing. The code before the int casts compiled
into an object file but the compiler through bash''s stderr gave me warnings
that I needed casts. Have I corrected a portability problem. It''s not good
to guess things even if it''s right but to know what you did.

As I said before, this Bill Cunningham person is a troll.
Yet a lot of people ignore me and continue to respond...Either a troll or completely unable to learn the language. It''s a
complete waste of time to attempt a dialog.

0, not portable? How about 1 or 2?

but is trying to learn C in spite of it. I''ve seen no reason to
disbelieve him.He''s supposedly been learning C since 2002 or so, and has made no more
progress than this. If he''s not a troll, then everyone needs to realize
that it ain''t gonna happen.
