COS3711 Assignment 2 2024 | Due 18 July 2024

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.

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.
