, 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. Question 2 Extend the solution in
Question 1, to add another class named RegistrationListWriter that produces
an XML-formatted RegistrationList using DOM as follows: <registrationlist>
<registration type=
To address the problem described, we need to create a GUI application in Qt that manages
conference registrations based on the provided UML class diagram. Here’s a step-by-step
approach to achieve this:
Step 1: Define the Classes
Based on the UML diagram and additional requirements, we have the following classes:
1. Registration
o Represents a single registration with a name, email, and registration type.
