0-100, guess the number ()

Don't talk nonsense, go directly to the code

#include <stdio.h>
int main()
{
    
    
    int num[999]={
    
    0},i=0;
    srand((unsigned)time(NULL));
    int a=rand()%100;//调用函数，随机生成[0,100]；
    printf("*******************\n");
    scanf("%d",&num[0]);
    while(num[i]!=a)
      {
    
    
          printf("*******************\n");
         if(num[i]>a) printf("你输入的数字偏大!!!\n");
         if(num[i]<a) printf("你输入的数字偏小!!!\n");
          printf("*******************\n");
         i++;
          scanf("%d",&num[i]);
      }

     printf("你猜对了!!!\n");
     printf("*******************\n");
     return 0;
}
