COS3711 Assignment 2 Questions and Answers 2024

Assignment 2 1. Introduction Please use CMake (and not qmake) when setting up your assignment projects. Qt Designer should not be used to design user interfaces, and you are expected to manually set up GUIs to ensure that you properly handle memory using Qt’s parent-child functionality. Good programming practices should be followed. Follow standard naming conventions: class names start with a capital letter, variable and function names start with a lowercase letter, using camelCase for names made up of multiple words. Ensure consistent code layout and use of blank lines. Use forward class declarations in header files. Use initialiser lists in constructors. Have proper GUI management: setting cursor focus, sequential tabbing, clearing input widgets (like text input fields being cleared and spin boxes being returned to some default value), and enabling and disabling buttons as appropriate. Provide appropriate user feedback. Your code should build and run without any warnings. 2. Questions lOMoARcPSD|14985576 Question 1 Study the following UML class diagram: The UML class diagram is an initial design of classes for a conference registration application. There are three types of registration allowed for the conference: standard registration, student registration and invited guests registration. The standard registration fee is the standard fee (stored in STANDARD_FEE). For those registered as students, the conference fee is half the price of the standard registration fee. For those registered as guests, the conference fee is 10% of the standard registration fee. An instance of RegistrationList contains a list of Registration*. No two registrations are allowed to have attendees with the same e-mail addresses, unless the names are different. You should be able to query a RegistrationList whether a person (by the name) is already registered for the conference. A RegistrationList can also return the number of attendees that are registered for the conference from an institution. Similarly, you can request the total registration fees for a type (“Registration”, “StudentRegistration”, “GuestRegistration” or “All”) of registration. You are expected to use Qt’s metaobject system to access the type of a Registration in RegistrationList.
