自己调了半天找不到问题......

求大佬调

代码

#include<iostream>
using namespace std;

bool sc = false; //strange char
int bsn = 0; //big letter,small letter,number

bool check(string s){
	if(s.size() > 12 || s.size() < 6) return false;
	else{
		for(int i=0; i<s.size(); i++){
			if(s[i] >= '0' && s[i] <= '9') bsn++;
			else if(s[i] >= 'A' && s[i] <= 'Z') bsn++;
			else if(s[i] >= 'a' && s[i] <= 'z') bsn++;
			else if(s[i] == '!' || s[i] == '@') sc = true;
			else if(s[i] == '#' || s[i] == '$') sc = true; 
		}
		if(sc && bsn >= 2) return true;
		return false;
	}
}

int main(){
	bool flag = false;
	string str;
	getline(cin, str);
	
	
	string st;
	for(int i=0; i<str.size(); i++){
		if(str[i] == ','){
			flag = true;
			if(check(st)) cout<<st<<endl;
			st = "";
			continue;
		}
		st += str[i];
	}
	
	if(!flag){
		if(check(st)) cout<<st<<endl;
	}
	
	return 0;
}
