CSP Unit 3 Review

I. Gathering feedback from potential users about what features they would like in the app.

II. Testing small parts of the app while it is being developed to find problems early.

III. Ignoring user feedback and only focusing on finishing the code quickly.

Which of the following actions would most likely help when designing and developing an app?

• I only

• I and II only

• II and III only

• I, II, and III

Which of the following best explains the purpose of a design plan when creating an app?

• Recording bugs that are discovered during testing

• Explaining how the program should function and how users will interact with it

• Listing all the programming commands used to build the app

• Writing down questions to ask users after the app is completed

Which of the following best explains the difference between sequential programming and event-driven programming?

• Sequential programming runs instructions in the order they appear, while event-driven programming runs certain instructions when a user action or event occurs.

• Sequential programming only works with user input, while event-driven programming does not allow user interaction

• Sequential programming runs multiple instructions at the same time, while event-driven programming runs one instruction at a time.

• Sequential programming is used for games, while event-driven programming is only used for websites

Which of the following is NOT a purpose of adding comments to a program?

• Helping programmers remember what certain parts of the code do

• Making it easier for other programmers to understand the program

• Allowing the computer to run the program faster

• Helping programmers keep track of changes or ideas while coding

Which statement correctly describes how code runs inside and outside an onEvent block?

• Code inside an onEvent runs immediately when the program starts

• Code outside an onEvent only runs when the user clicks something

• Code outside an onEvent runs right away, while code inside runs when the event happens

• Code inside and outside an onEvent always run at the same time

What is the purpose of the onEvent block in a program?

• It allows the program to respond when a user interacts with the app

• It runs all code in the program at the same time

• It automatically fixes errors in the program

• It runs code continuously without stopping

What will happen if code is written after an onEvent block but is not inside any onEvent?

• It will not run at all

• It will only run when the event happens

• It will cause the program to stop working

• It will run when the program starts, before the event occurs
