,Question 1:
Write an application that can be used to keep a list of staff member details. Each staff member
data should include the following:
1. A name
2. A birthdate, and
3. A staff appointment type (one of permanent, part-time, or contract, stored and handled as an
enum).
Include all necessary getter and setter functions. An additional getter can be used to return the
appointment type as a Qstring. The application should allow a user to enter details via a GUI. Also,
once a staff member’s details are entered, they should be saved to a list/container in the application.
The user should be able to write this list to file (in any acceptable, human-readable format) when
needed.
Ensure that you adhere to basic design principles and avoid any anti-patterns in the design of
your solution.
Discussion:
The application consists of three classes: MainWindow, StaffMember, and
StaffListModel. In the initial solution provided, the StaffMember class is responsible for
storing the details of a staff member, including their name, birthdate, and staff appointment type. In
the first part of the solution, the StaffMember class is defined with three private data members -
m_name, m_birthdate, and m_staffAppointment. These data members represent the
name, birthdate, and appointment type of a staff member, respectively.
The StaffMember class also provides public getter and setter functions for each of its private
data members, allowing external code to access and modify the staff member's information.
Additionally, the class provides a function that returns a string representation of the staff member's
information.
Overall, the StaffMember class encapsulates the data and behaviour related to an individual staff
member, providing a clean and modular way to represent and manipulate staff member information
in the application.
