请问各位大佬，为什么存不进去数组呀！这是什么情况啊

Question

这是相关头文件

#pragma once
#include<string>
#include<iostream>
#include"User.h"
#include"SafeSystem.h"
using namespace std;

class oneaccount
{
public:
    User accpass[1000];
    string name;
    string password;
    int accountlen;

    void showlogin();                   //注册
    void loginaccount();                //登录
    void showall();                     //展示所有账号和密码

    oneaccount();
    ~oneaccount();
};

字符串的比较用strcmp不是==
而且不能用
if (accountsz[accountlen] == "\0")
判断字符串数组中有多少有效的元素
