QUIZ APCSP 1

A team is developing a new mobile app. They create a simple, clickable model that shows the user interface and flow between screens, but it has no real functionality. This model is best described as a:

• Final algorithm

• Prototype

• Debugging report

• Data set

The process of identifying and correcting errors in a computer program is known as:

• Debugging

• Documenting

• Prototyping

• Iterating

You find a piece of code online written by another developer. What is the best practice for using it in your own project while avoiding plagiarism?

• Copy the code exactly, as anything online is free to use.

• Change the variable names to make the code look different.

• Use the code but provide attribution or citation to the original author in your documentation.

• Re-type the code manually instead of copying and pasting it.

Which of the following best describes an iterative development process?

• A process where the entire program is designed, built, and tested in one single sequence.

• A process that focuses only on user feedback after the product is fully launched.

• A process that repeats cycles of designing, prototyping, and testing to refine a solution.

• A process where development is outsourced to many different collaborators.

A team is building an app to help students manage their homework. The app needs to store deadlines, subject names, and task descriptions. This information is considered the app's:

• Algorithm

• Data

• Output

• Processor

A software development team is building a complex navigation app for hikers. They decide to release a basic version with only trail mapping first. After gathering user feedback for a month, they plan to add an elevation tracking feature, and later, a weather alert feature. This approach primarily demonstrates which computing concept?

• Top-down design, because the most complex features are planned last.

• Iterative development, because the app is refined and expanded in cycles based on feedback.

• Data abstraction, because the user does not see how the map data is stored.

• Debugging, because they are using feedback to find flaws in the initial version.

A team is building a medical records system. They decide to use a pre-built, third-party database module to handle all data storage and retrieval. This decision is a form of:

• Abstraction

• Iteration

• Debugging

• User-centered design

Which of the following scenarios best illustrates the benefit of collaboration over individual work in solving a complex computational problem?

• A single programmer writes code faster and with fewer syntax errors when working alone.

• A programmer finds and fixes a logical error in their own code after stepping away for an hour.

• One developer builds the user interface, while another developer builds the database, allowing them to finish the project in parallel.

• A team of programmers all review a single algorithm and, by combining their different perspectives, identify a critical security flaw that one person missed.

A large software project for an airline's booking system is divided into modules: one for user authentication, one for flight searches, and one for payment processing. Different teams develop these modules concurrently and then integrate them. This strategy primarily addresses the challenge of:

• Managing project complexity

• Determining the program's purpose

• Preventing all logic errors

• Ensuring user data is biased

A program is written to calculate a 5% discount. The line of code is totalCost = price 0.95;. The programmer intended to give a 5% discount but accidentally wrote code that charges 95% of the price (which is correct). The program runs perfectly without crashing. If the programmer had instead written totalCost = price * .05; (charging only 5%), this would be an example of what type of error?

• syntax error

• runtime error

• logic error

• attribution error
