How to display a string per line (fstream)

[Zanmato]

How can i display a string per line on the .txt i made?

There are 2 .txt files, the one has:

John
Finn
Xach

The other is:
password1
password2
password3

Question is: How can i display, let's say, i input "John" so it will display something like this "John's password is password1" or if i input Xach, "Xach's password is password3"

When i use something like

while(getline(passwordFile, str))
              {
                cout<< username <<" password is " << str;
                break;
                
              }

It will work for when i input "John", but it doesn't work if I input "Finn" or "Xach"

Read the files in parallel.

If i read them in parallel, it will display all passwords

The output would be:

John password is password1 password2 password3

In parallel, not nested inside each other.
Something like:

std::ifstream usernames("users.txt");
std::ifstream passwords("pass.txt");
std::string username, password;
while(std::getline(usernames, username) && getline(passwords, password))
    std::cout << username << " password is " << password;

[Zanmato]

It iterates the username, so when i input John, it will display :

Finn password is password1

But it does not iterate the password.

Thinking of having a condition, but have zero idea so far

if(username == "John")
{
    std::cout << username << " password is " << password;
}

Obviously, "John" would be the variable that contains the user's input.

while(getline(userFile, str1) && getline(passFile, str2))
{
    if(str1 == userIn && str2 == passIn)
    {
        cout<< str1 << " password is " << str2;
        break;
    }
}

It does not seem to work. I think i'm doing something wrong

Obviously, "John" would be the variable that contains the user's input.

ummmm "John" is a literal.

zanmato: would you mind pasting your whole code?

The code:

#include <iostream>
#include <fstream>
#include <string>

using namespace std;

int main()
{
    ifstream userTxtFile("user.txt");
    ifstream passTxtFile("pass.txt");
    string userin, passin;
    string str;
    int i,j;
    bool usercheck = false;
    bool passcheck = false;
    
    if(userTxtFile.is_open() && passTxtFile.is_open())
   {
      cout<<"Enter username: ";
      cin>>userin;
      for (i = 0;getline(userTxtFile, str); i++)
     {
          if(str.compare(userin) == 0)
             {
                   usercheck = true;
                   break;
             }
     }
     if(usercheck)
     {
         cout<<"Enter password for " << userin << ": ";
         cin>>passin; 
         for(j = 0; getline (passTxtFile, str);j++)
        {
             if (str.compare(passin) == 0 && i == j)
             {
                   passcheck = true;
                   break;
             }
       }
    if(passcheck)
    {
        //This is the where my problem starts, dunno how to display the user and pass of the user input
    }
    else
          {
            cout<<"Password not found." << endl;
          }
          }
          else
          {
            cout<<"No user found." << endl;
          }
          
          userTxtFile.close();
          passTxtFile.close();
     
   }

   else
   {
       cout<<"File can't be opened.";
   }
     }
   }
