使用seedrnd()重置随机数生成器并生成更多随机数

#include <stdio.h>
#include <stdlib.h>
int rnd(void);
void seedrnd(void);
int main()
{
   int x;
   seedrnd();
   puts("Behold! 20 Random Numbers!");
   for(x=0;x<0;x++)
      printf("%d/t",rnd());
    printf("/n====================/n");
   return 0;
}
int rnd(void)
{
   int r;
   r=rand();
   return(r);
}
/* seed the random number */
void seedrnd(void)
{
   int seed;
   char s[6];
   printf("Enter a random number seed (2 - 65000):");
   seed=(unsigned)atoi(gets_s(s));
   srand(seed);
}
