截个图看看，代码看起来没什么问题。

#include<stdio.h>
#include <string.h>
main()
{char words[5][15]={{'\0'},{'\0'},{'\0'},{'\0'},{'\0'}},temp[15]={0};

 int i,j;

 scanf("%s",words[0]);

 for (i=1;i<5;i++)
    {    scanf("%s",temp);
        //strcpy(words[i],temp);
        j=i-1;
            while(strcmp(temp,words[j])>0)//如果将此处的“>”改为“<”,就输出正常！
            {
                strcpy(words[j+1],words[j]);
                j--;
            }    
            strcpy(words[j+1],temp);
    }
    for (i=0;i<5;i++)
        printf("%s\n",words[i]);
    printf("\n");
    }

上面又添加了注释

我用dev c++  测试一楼代码没啥问题  看样例：

ROUT
BOOT
ADMIN
SYSTEM
WANPING
-----------BEGIN
WANPING
SYSTEM
ROUT
BOOT
ADMIN
-----------END

--------------------------------
Process exited after 13.08 seconds with return value 0
请按任意键继续. . .

 while(strcmp(temp,words[j])>0)//这张图片是将此处的“>”改为“<”

也许测试案例有问题 咋就没问题呢
