Я начал изучать C ++ 3 дня назад, и после некоторых экспериментов с циклами и вектором я решил сделать с ним что-то действительно полезное: менеджер учетных записей.
Дело в том, что я использую do.... while цикл, для первого действия в моей программе (которое добавляет новый веб-сайт), однако после этого этапа цикл не завершится, даже если условие больше не выполняется.
Iпытался отладить его в течение хороших 30 минут и не нашел ничего странного.
Вот код:
#include <iostream>
#include <string>
#include <vector>
using namespace std;
int main()
{
/*Introduction
//Ask whether the user(me) wants to open an account already created, add a new one, or remove an existing one
To show credentials a master password is required
I need something that can:
1. Find the place where credentials are supposed to be filled
2. Enter them efficiently
3. Bonus : Submit the data on the website and automatically connect*/
int userAction; // Variable de sélection de la première action
string siteNameVar("site"), urlVar("url"), userNameVar("username"), passwordVar("pass") ;
char sureVerification;
vector<string> siteName(0); // Vectors containing respectively : "The sites names"
vector<string> url(0); // Vectors containing respectively : "The sites urls"
vector<string> userName(0); // Vectors containing respectively : "The usernames"
vector<string> password(0); // Vectors containing respectively : "The passwords"
cout << "What will you do?" << endl;
cout << "1. Add a website account" << endl
<< "2. Connect to an existing account" << endl
<< "3. Delete an account"<< endl;
cin >> userAction; // This is where the user enter his choice
switch (userAction){
case 1: // Add a new element in the vectors
do{
//Site Name
do{
cout << "Enter the site's name (or how you want to call it)" << endl;
cin >> siteNameVar;
cout << "Are you sure? 1 = yes | Anything else = no" << endl;
cin >> sureVerification;
}
while (sureVerification != 1);
//Site's Url
do{
cout << "Enter the site's login page url" << endl;
cin >> urlVar;
cout << "Are you sure? 1 = yes | Anything else = no" << endl;
cin >> sureVerification;
}
while(sureVerification != 1);
url.push_back(urlVar);
// Username
do{
cout << "Enter your account's username" << endl;
cin >> userNameVar;
cout << "Are you sure? 1 = yes | Anything else = no" << endl;
cin >> sureVerification;
}
while(sureVerification != 1);
userName.push_back(userNameVar);
// Password
do{
cout << "Enter your account's password" << endl;
cin >> passwordVar;
cout << "Are you sure? 1 = yes | Anything else = no" << endl;
cin >> sureVerification;
}
while(sureVerification != 1);
password.push_back(passwordVar);
//Display Everything
cout << "So the site's name is :" << siteName.back() << endl
<< "The login page url is :" << url.back() << endl
<< "Your account's username is :" << userName.back() << endl
<< "And your password is :" << password.back() << endl;
//Last verification
cout << "Is everything alright? 1 = yes | Anything else = no" << endl;
cin >> sureVerification;
}
while(sureVerification != 1);
cin.get();
break;
case 2: // Connect to an existing account
cout << "display map element names" << endl;
break;
case 3: // Delete an account
cout << "display map element names2" <<endl;
break;
} // End of the choice sequence
cin.get();
return 0;
