PAT乙级1081-----检查密码 (15分)

1081 检查密码 (15分)

 

 

输入样例：

5
123s
zheshi.wodepw
1234.5678
WanMei23333
pass*word.6

 

输出样例：

Your password is tai duan le.
Your password needs shu zi.
Your password needs zi mu.
Your password is wan mei.
Your password is tai luan le.

思路：
1.注意计算小数点的数量
2.测试点2会有空格，因此要用gets()

首次通过代码:

#include<stdio.h>
#include<string.h>

int main(){
    char password[81];
    int sum;
    scanf("%d",&sum);
    getchar();
    for(int i=0;i<sum;i++){
        int num=0,letter=0,dot=0;
        gets(password);
        if(strlen(password)<6) printf("Your password is tai duan le.");
        else {
            for(int j=0;j<strlen(password);j++)
               {if(password[j]>='0'&&password[j]<='9') num++;
               else if(password[j]>='a'&&password[j]<='z'||password[j]>='A'&&password[j]<='Z') letter++;
               else if(password[j]=='.') dot++;
               }
               if(num+letter+dot<strlen(password)) printf("Your password is tai luan le.");
               else if(num==0&&letter>0) printf("Your password needs shu zi.");
               else if(letter==0&&num>0) printf("Your password needs zi mu.");
               else printf("Your password is wan mei.");
                
        }
        if(i!=sum-1) printf("\n");
    }
    return 0;
}
