参考代码:

#include<stdio.h>
#include<string.h>
int main()
{
   int x;
   scanf("%d",&x);
   getchar();
   while(x--)
   {
       int a=0,b=0,c=0,d=0;
       char s[100];
       scanf("%s",s);
       int length;
       length=strlen(s);
       if(length>16||length<8)
       {
           printf("NO\n");
           continue;
       }
       for(int i=0;i<length;i++)
       {
           if(s[i]<='Z'&&s[i]>='A')
            a=1;
           if(s[i]<='z'&&s[i]>='a')
            b=1;
           if(s[i]<='9'&&s[i]>='0')
           c=1;
           if(s[i]=='~'||s[i]=='!'||s[i]=='@'||s[i]=='#'||s[i]=='$'||s[i]=='%'||s[i]=='^')
           d=1;
       }
       if(a+b+c+d>=3)
        printf("YES\n");
       else
        printf("NO\n");

   }

    return 0;
}
