让字符串在密码函数中工作

您好，我对我的解释很抱歉，我对此很陌生。我目前正在研究密码功能，但遇到了问题。我已将帐户名设置为字符串“john”，将帐户密码设置为 int 1111。密码工作正常，但该字符串导致错误。当我将“const string name =”john“”更改为随机整数时，代码工作正常。

我希望有人能发现我哪里出错了？

bool login() {

   const int password = 1111; 
   int passwordAttempt;
   const string name = "john";
   string nameAttempt;
   int attempts = 0;

   std::cout << "Please Enter Password:" << std::endl; //first attempt at account number & password
   std::cin >> passwordAttempt;
   std::cout << "Enter Name:"<< std::endl;
   std::cin >> nameAttempt;

if (passwordAttempt == password && nameAttempt == name) {
   return true;
   } 

else 

while (passwordAttempt!=password || nameAttempt!=name) {
     if(attempts++ ==2)//.. a loop for two more attempts
     {
       std::cout << "You have entered the wrong details three times. The application will be terminated now" << std::endl;
       return false;
       break;
     }
       std::cout<<"Incorrect password. Try again"<<std::endl;
       std::cout<< "" <<std::endl;
       std::cout << "Please Enter Password:" << std::endl;
       std::cin >> passwordAttempt;
       std::cout << "Enter Name:"<< std::endl;
       std::cin >>nameAttempt;
     }

     }




using namespace std;

int main() {

bool loggedIn = login();

if (loggedIn){
cout << "Logged In" << endl;
}

else if (!loggedIn){
cout << "Not Logged" << endl;
}

system("pause");
return 0;
}

1. Add std::到你的字符串声明（所以你将有std::string).
2. while 循环结束后，函数结束login没有任何价值回报。添加return true那里。并且始终在启用警告的情况下进行构建！
