供参考：

#include <stdio.h>
#include <string.h>
char* reverseWords(char* s) 
{
    int k, j, len = strlen(s), cnt = 0;//一个单词长度
    for (int i = 0; i <= len; i++)
    {
         if (s[i] == ' ' || s[i] == '\0')
         {
             k = i - cnt;
             cnt = 0;
             for (j = i - 1; j > k; k++, j--)
             {
                  char tmp = s[k];
                  s[k] = s[j];
                  s[j] = tmp;
             }
         }
         else{
              cnt++;
         }
    }
    return s;
}
int main()
{
    int n = 1;
    char arr[128] = "uoY era gip", * str;
    scanf("%d\n", &n);
    while (n--){
          gets(arr);
          str = reverseWords(arr);
          puts(str);
    }
    return 0;
}
