    So I am having 2 issues with my code:

    The one is displaying the username and password in the QMessagebox and the other is generating the random password from the appended string.

    I am sure it is some small issues but I am not picking it up. I am using QT 5.3.0

    Here is my code:

    @// Declarations of variables
    bool ok;
    QString fullName;
    QString userName;
    QString passWord;
    QString genPass;

     fullName = QInputDialog::getText(0,"Username","Please Enter Name and Surname:", QLineEdit::Normal," ", &ok);
    
    
     if (ok && !fullName.isEmpty()) {
     QStringList elements = fullName.split(" ");
     userName = elements[0].left(4) + elements[1].left(1);
     }
    
    
     //If username is less than five characters
     while (userName.length() < 5) {
         userName += '0';
     }
    
    
     //Remove all whitespaces from string
     userName = userName.simplified();
     userName.replace( " ", "" );
    
     //First letter of username to uppercase
          userName = " ";
          userName.replace(0, 1, userName[0].toUpper());
    
          passWord = userName;
    
          //For loop to generate random password of 5 characters from concatenated name/surname string
          for (int i = 0; i < 5; i++){
              passWord[i] = genPass [qrand() % (sizeof (genPass) -1)];
    
           do{
                 passWord[i] = genPass [qrand() % (sizeof (genPass) -1)];
                }while (passWord[i] = ' ');
                                                  }
    
    
            //QMessageBox to display username and password
                    QString response = QString(" Username: %1 \n Password: %2") .arg(userName).arg(passWord);
                     QMessageBox::question(0, "Username and Password", response, QMessageBox::Ok);
    

    return EXIT_SUCCESS;
    }

      Hi SGalst, is there a better way to do the password generator.

          Just 2 issues:

          1. The QMessageBox is not displaying the concatenated username or the password.

          2. My randomizer is not generating random 5 character passwords from the concatenated first name and surname.

          I will look at the link as well.

          Thanks

              Nothing at all. It just pops up when I press OK and shows the username: and password: but with no data.

                @ //First letter of username to uppercase
                userName = " "; << You're a replacing userName content with a space
                userName.replace(0, 1, userName[0].toUpper());
                @

                  Thanks, that fixed the username display issue.

                  When I enter the fullname of john black , I get Johnb instead of Blacj

                    Like I said, using only one input your user can put their information in the order they want so first name/last name or last name/first name. You really should write a little custom dialog that uses two QLineEdit for that. It will be clearer for your users
