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.
To tackle this task, let's break it down into the following steps:
1. Understand the UML Diagram and Classes: Review the given UML class diagram and
understand the structure of the classes and their relationships.
2. Define the Classes: Implement the classes as specified in the UML diagram. These
classes will include Registration, StudentRegistration, GuestRegistration, and
RegistrationList.
