求大神帮我看看哪错了 70分！！！

#include <bits/stdc++.h>
using namespace std;
string s, temp;

bool k(string s){
	int a = 0, b = 0, c = 0, d = 0, e = 0;
	for(int i = 0;i < s.size();i++){
		if(s[i] >= 'a' && s[i] <= 'z') a = 1;
		else if(s[i] >= 'A' && s[i] <= 'Z') b = 1;
		else if(s[i] >= '0' && s[i] <= '9') c = 1;
		else if(s[i] == '!' || s[i] == '@' || s[i] == '#' || s[i] == '$') d = 1;
		else e = 1;
	}
	if(d == 0 || s.size() < 6 || s.size() > 12 || e == 1) return 0;
	if(a == 0 || b == 0 || c == 0 || d == 0) return 0;
	return 1;
}

int main(){
	cin>>s;
	for(int i = 0;i < s.size();i++){
		if(s[i] != ','){
			temp += s[i];
		}else{
			string test = temp;
			if(k(test) == 1) cout<<test<<endl;
			temp = "";
			
		}
	} 
	return 0;
