COS3711 Assignment 2 2024 - DUE 18 July 2024
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. Downloaded by Corona Virus () lOMoARcPSD| Write a
GUI application that allows users to register for a conference. The GUI should display the
current list of registrations, including the respective registration fees, in the
RegistrationList at all times, using a table widget. The interface should also allow users to
request and view the results of the various operations supported by the RegistrationList
class. You are allowed to add new features to the classes given in the UML diagram,
although you are not allowed to delete or change the given functions. You can decide on
the design of the GUI, and it can be done manually or using Qt Designer. You are
expected to follow good programming principles.
