QUESTION 1
Sure, let me provide a high-level design and implementation outline for the application
using C++ with the Qt framework. We'll create the necessary classes to handle this
functionality while ensuring proper separation of concerns.
### High-Level Class Structure
1. Staff class: Represents an individual staff member.
2. StaffList class: Manages a list of Staff objects.
3. StaffWriter class: Handles writing Staff objects to a file.
4. MainWindow class: Provides GUI for user interaction.
