To correctly pair an example with event-driven programming and sequential-driven programming, we need to understand the difference between the two:
-
Event-driven programming: This paradigm is primarily focused on the occurrence of events. The flow of the program is determined by events such as user actions (clicks, typing, etc.), sensor outputs, or messages from other programs. Applications that rely on user interactions are often event-driven.
-
Sequential-driven programming: This is a more traditional programming model where statements are executed in a linear or sequential manner. The program follows a predefined path and usually does not depend on events.
Now let's evaluate the options provided:
-
Event-driven programming – a music application that allows users to create playlists: This is correct since users can interact with the application (input events), which drives the application's behavior.
-
Sequential-driven programming – a shopping list application that users can add and remove items from: This is not entirely accurate since a shopping list application often relies on user input to add or remove items, making it more event-driven.
-
The mixed pairing where:
- Event-driven programming – a music application that allows users to create playlists
- Sequential-driven programming – a shopping list application that users can add and remove items from This pairing correctly identifies the music application as event-driven but misclassifies the shopping list application. It should also be considered event-driven because it handles user input dynamically.
-
Event-driven programming – a shopping list application that users can add and remove items from: This is more accurate in its classification since a shopping list reacts to user actions.
-
Sequential-driven programming – a messaging application that lets users call people: This is incorrect because a messaging application is typically event-driven due to user actions.
-
Event-driven programming – an application that displays all the letters for kids to learn: This might be sequential unless it has interactive features.
-
Sequential-driven programming – a music application that allows users to create playlists: This is incorrect as music applications are generally interactive and event-driven.
From the above evaluations, the correct pairing is:
Event-driven programming – a music application that allows users to create playlists.
Since other interpretations may vary but generally, a shopping list application where items can be added or removed would also be classified within event-driven contexts.
