引起一些问题 [英] strlen causing some issues

问题描述

 

由于某种原因，当我尝试编译该程序时，发生了奇怪的事情，例如文件名更改为"string.h".有任何想法吗?

For some reason when I try to compile this program strange things are happening like the file name is changed to "string.h". Any ideas?

#include <stdio.h>
#include <string.h>

int main()

{
    char str1[20] = "Hello\0" ;
    char str2[20] = "everyone\0" ;
    printf("%i\n",strlen(str1)) ;
    printf("%i\n",strcmp(str2)) ;
    return 0;
}

推荐答案

标准的strcmp()函数使用两个参数，因为它比较了两个字符串.我很惊讶您的编译器甚至可以在其中编译带有"strcmp(str2)"的行，这真的不应该.

The standard strcmp() function takes two arguments, since it compares two strings. I''m surprised your compiler will even compile that line with "strcmp(str2)" in it -- it really shouldn''t.

顺便说一句，您不必在定义的字符串的末尾添加"\ 0".

By the way, you don''t have to add "\0" to the ends of the strings you define. The compiler will do that for you.

我认为strcmp应该比较2个字符串.

I thought strcmp was supposed to compare 2 strings.

哪个文件正在更改为string.h?上面的代码所在的文件?

And which file is changing to string.h? The file that the above code is in?
