解题思路:

注意事项:

参考代码:

#include "stdio.h"

#include "string.h"

int main()

{

int n; scanf("%d", &n);

for (int i = 0; i < n; i++) 

{

getchar();

char s[100];

int a = 0, b = 0, c = 0, d = 0;

gets(s);

for (int j = 0; s[j] != '\0'; j++) 

{

if (s[j] >= 'a' && s[j] <= 'z') { a = 1; }

if (s[j] >= 'A' && s[j] <= 'Z') { b = 1; }

if (s[j] >= '0' && s[j] <= '9') { c = 1; }

if (s[j] == '!' || s[j] == '$'||s[j]=='@'||s[j]=='^'||s[j]=='~'||s[j]=='%' ||s[j]=='#') { d = 1; }

}

if (a + b + c +d>= 3 && strlen(s) >= 8 && strlen(s) <= 16)

{

printf("YES\n");

}

else printf("NO\n");

s[strlen(s)] = '\0';

}

}
