COS2614 Assignment 1 2023 Answers, guidelines, workings and references. ............................................. Question 1 Write a Qt Graphical User Interface (GUI) program to generate a username and an initial password given the full name of the user. Given below are the rules for generating a valid username: • It consists of 5 characters, where the first character is in upper case and the rest of the four characters are in smaller case. • The user name is created by combining the first 4 characters of the surname with the first character of the first name. • If the surname does not have 4 characters, more characters are taken from the first name to make up the user name. • If the surname and the first name combined is less than 5 characters then append sufficient number of 0s to create the username. An initial password is generated by combining randomly selected 5 characters from the full name of the user. Note than no spaces are allowed in the username or password. User input should be obtained using a QInputDialog. You can expect the full name as a single string where each word is separated using a space. For example: Mike William Owen. The output (username and password) should be displayed using a QMessageBox. You need not do any verification of the user input. Question 2 Implement the following classes in the UML class diagram according to the description that follows: A product is described using a name, a price and a supplier. The supplier and the manufacturer can be the same for a product. A Product is initialised using a name and a price. The supplier details are set using the function setSupplier(), which invokes the suitable function of Vendor to set the details of the vendor. If one requests a product for its manufacturer, it returns the name of the vendor stored in m_Supplier, if it is set as the manufacturer. Otherwise an Unknown string is returned. toString() of Vendor returns a string representation of the values of its data members in a readable format. toString() of Product always returns a string representation of a product. If supplierDetails in toString() of Product is true, it returns both the supplier and product details. Otherwise only product details are returned. Implement it as a console application, where the product and supplier details are entered from the keyboard. Display the results of getManufacturerName() and toString()(for both true and false parameter values) on the console.
