@BH9570

first,输入最后没有逗号，所以最后一个密码你没有检测。

second，

大写字母，小写字母和数字必须至少有其中两种，以及至少有四个特殊字符中的一个。

但是你判断条件写的是'&&'。

经过上述修改：

#include<bits/stdc++.h>
using namespace std;
int main () {
    string s;
    cin >> s;
    s.push_back(',');
    string t = "";
    for (int i = 0; i < s.size(); i++) {
        if (s[i] != ',') {
            t.push_back(s[i]);
            continue;
        }
        bool b = 0;
        int c1 = 0,c2 = 0,c3 = 0;
        bool flag = 0;
        for (int j = 0; j < t.size(); j++) {
            if (t[j] >= 'a' && t[j] <= 'z') {
                c1 = 1;
            }
            else if (t[j] >= 'A' && t[j] <= 'Z') {
                c2 = 1;
            }
            else if (t[j] >= '0' && t[j] <= '9') {
                c3 = 1;
            }
            else if (t[j] == '!'|| t[j] == '@' || t[j] == '#' || t[j] == '$') {
                b = 1;
            }
            else {
                flag = 1;
                break;
            }
        }
        if (flag == 0 && (c1 + c2 == 2 || c2 + c3 == 2 || c1 + c3 == 2) && b == 1 && t.size() <= 12 && t.size() >= 6) {
            cout << t << endl;
        }
        t = "";
    }
    return 0;

谢谢，已关！@Florrer_A @shanxiwen

@Florrer_A大神，我看不懂

by BH9570 @ 2024-11-24 19:19:41

我赞成@shaoxiaohang ，像什么“cin.tie(0)”都没听过
