What is the primary purpose of a Graphical User Interface (GUI) in a software application?

To improve the performance and execution speed of the underlying application logic

To provide a visual, interactive way for users to control and interact with the application

To automatically generate documentation for the application's source code

To store application data in a structured database for later retrieval

A developer is designing a settings dialog for an application. The dialog needs a drop-down list for selecting a theme, a checkbox for enabling notifications, and a slider for adjusting volume. Which set of widgets should the developer use?

Listbox, Radiobutton, and Spinbox

Combobox, Checkbutton, and Scale

A developer is building a desktop utility that must respond to user clicks on a button, keyboard shortcuts, and window resizing. The application should remain responsive while waiting for user input, rather than executing a fixed sequence of steps. Which programming model should the developer use, and what is its defining characteristic?

Event-driven programming, where the program runs an event loop that dispatches callbacks in response to user actions.

Classical programming, where the program executes top-to-bottom and terminates when the last statement runs.

Visual programming, where the developer drags and drops components to define the execution flow.

Functional programming, where the program is a composition of pure functions called in a fixed order.

How does visual programming typically aid a developer when building a GUI?

It eliminates the need to write any code for event handling

It allows the developer to see the interface layout in real time while placing widgets

It replaces the need for a compiler or interpreter

It automatically optimizes the application's memory usage
