1081 检查密码

当输入为多行是，最好声明变量为string类型，用getchar()吃掉输入n时按的回车，用getline(cin,s)读入字符串变量

#include<iostream>
#include<cstring>
#include<algorithm>
#include<cstdio>
using namespace std;
int main ()
{
	int n;
	cin>>n;
	getchar();
	string s;
	while(n--)
	{
		getline(cin,s);
		int m=s.length();
		if(m<6)
		{
			cout<<"Your password is tai duan le."<<endl;
			continue;
		}
		else
		{
			bool shuzi=false,zimu=false,hefa=true;
			for(int i=0;i<m;i++)
			{
				if(s[i]>='0'&&s[i]<='9')
					shuzi=true;
				else if((s[i]>='a'&&s[i]<='z')||(s[i]>='A'&&s[i]<='Z'))
					zimu=true;
				else if(s[i]=='.');
				else
				{
					hefa=false;
					break;
				}
			}
			if(!hefa)
				cout<<"Your password is tai luan le."<<endl;
			else if(!shuzi&&zimu)
				cout<<"Your password needs shu zi."<<endl;
			else if(!zimu&&shuzi)
				cout<<"Your password needs zi mu."<<endl;
			else
				cout<<"Your password is wan mei."<<endl;
		}
	}
	return 0;
}
