我收到以下 C 程序的错误消息，该程序假设将字符串中的一个单词更改为大写字母。

1>verkefni06.obj : error LNK2019: unresolved external symbol _strhlt referenced in function _main
1>c:\kit\skilaverk06\Debug\skilaverk06.exe : fatal error LNK1120: 1 unresolved externals

这是我到目前为止得到的代码，非常感谢任何导致代码工作的帮助。

   i = 0;
    while (--lim > 0 && (c=getchar()) != EOF && c != '\n')
      s[i++] = c;
   s[i] = '\0';
   return i;

 int strhlt(char sz[], char szHigh[]);

   strcpy;

   getline (sz,60);

   strhlt (sz,"write" ); 
   getline ("%s",60);

There is no definition for strhlt() in your code and it is not a library function too.

only declaration is available.

int strhlt(char sz[], char szHigh[]);

so during linker time, you are getting this error.

int strhlt(char sz[], char szHigh[]);

链接编辑器正在寻找该函数的定义。它不在这个文件中。您是从其他地方链接它吗？

如果是这种情况，您需要一个extern

extern int strhlt(char sz[], char szHigh[]);
