Username and password. Can't get the true false thing in this code to behave correctly.

Question

PS it's long.
I can't wrap my head around why i get "login successfull" when the username is wrong:
So here's a very long code with an additional unessecary function call vy reference just for the fun of it:

#include<iostream>
#include<string>
#include<vector>

class Users
{
private:
std::string m_username;
std::string m_password;

public:

void setUsername(std::string username)
{
m_username = username;
}

void setPassword(std::string password)
{
m_password = password;
}

bool checkUsername(std::string username)
{
if (username == m_username)
{
return true;
}
else
{
return false;
}
}
bool checkPassword(std::string password)
{
if (password == m_password)
{
return true;
}
else
{
return false;
}
}

};

void setUsernameAndPassword(Users &user, std::string username, std::string password)
{
user.setUsername(username);
user.setPassword(password);
}

void menu(std::vector<Users> &userVector)
{
std::cout << "1.New user\n2.Open user" << std::endl;

int input;
std::cin >> input;

if (input == 1)
{

std::string username;
std::string password;
Users newUser;

std::cout << "Enter username: ";
std::getline(std::cin, username);
std::cin.ignore(std::numeric_limits<std::streamsize>::max(), '\n');

std::cout << "Enter password: ";
std::getline(std::cin, password);
//std::cin.ignore(std::numeric_limits<std::streamsize>::max(), '\n');

setUsernameAndPassword(newUser, username, password);

userVector.push_back(newUser);
}
if (input == 2)
{
//Print user id's
std::cout << "Available users: " << std::endl;

for (int n = 0; n < userVector.size(); n++)

Answer 1

Post the link to the whole code here; the URL.

Answer 2

Crap, it's not enough characters here. I will put it in my codes.
And you can copy it from there to explore it. this online compiler can't run it I think.

Answer 3

Answer 4

I just took a look at the code in Visual Studio and when I entered a wrong password, it didn't accept it. So I guess it has already been fixed.
