Question

这可能已经在某个地方得到了解答，但我花了几分钟时间寻找并且找不到任何东西。我有两个文件User.txt和Pass.txt。

Pass.txt看起来像这样：

password
test

User.txt看起来像这样：

username
test

这是我的代码：

        cout << "Username: " << endl; //input user
        cin >> user;
        cout << "Password: " << endl; //input pass
        cin >> pass;
        userfile.open("User.txt");
        passfile.open("Pass.txt");
        while (getline(userfile, STRINGT) && getline(passfile, STRINGO))
        {
            if (user == STRINGT.c_str() && pass == STRINGO.c_str()) //if user and pass are both in file
            {
                //i had a break here, (its in a switch) so i replaced it with a cout, but it didn't change
            }
        }
        cout << "Incorrect username or password" << endl;
        _getch(); //pause
        return 0; //end program

每当我跑步时，它都表示每次都不正确。我正在检查所有的帽子等等，无法解决问题。

我已经在上面声明了所有其他nessesary fstream文件

先谢谢C：

这就是你需要的：

    bool found = false;

    while (getline(userfile, STRINGT) && getline(passfile, STRINGO))
    {
        if (strcmp(user, STRINGT.c_str()) == 0 && strcmp(pass, STRINGO.c_str()) == 0) //if user and pass are both in file
        {
            found = true;
            break;
        }
    }

    if (!found) {
        cout << "Incorrect username or password" << endl;
    }

文件中的用户名和密码
