用C语言写一个产生字符串的随机排列的程序

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

void main()
{
int m;
char s1[]="26537";
char s2[]="monkey";
char s3[]="USA";
char s4[]="$&";
char s5[]="给我一首歌的时间";
srand(time(NULL));
m=rand()%5;
switch (m)
{
case 0:
printf("%s\n",s1);
break;
case 1:
printf("%s\n",s2);
break;
case 2:
printf("%s\n",s3);
break;
case 3:
printf("%s\n",s4);
break;
case 4:
printf("%s\n",s5);
break;
default:
break;
}
}

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

int main()
{
char *strs[5] = {"26537", "monkey", "USA", "$&", "给我一首歌的时间"};
