A developer is refactoring a legacy procedural script into a GUI application. The script currently reads input from a file, processes it, and writes output. The developer wants to preserve the core logic while adding a GUI for user interaction. Which approach is the most appropriate?

Rewrite the core logic to be event-driven, with callbacks for each step.

Convert the core logic to use a visual programming tool.

Run the core logic in a separate thread and block the GUI until it finishes.

Keep the core logic as a function and call it from an event handler in the GUI.

What is the defining characteristic of the classical (procedural) programming model?

The program executes statements in a sequential order from top to bottom

The program is divided into objects that communicate via messages

The program runs multiple threads simultaneously by default

The program waits for external events to trigger functions

What is the key difference between event-driven and classical programming?

Event-driven programs are always faster than classical programs

Event-driven programs respond to user actions, while classical programs follow a fixed sequence

Event-driven programs run on a single thread, while classical programs use multiple threads

Event-driven programs do not use functions, while classical programs do

In a GUI, what is the primary purpose of a button widget?

To display static text information to the user

To allow the user to enter multi-line text input

To trigger an action when clicked by the user

To organize other widgets into a hierarchical structure
