CS Principles Unit 3 Assessment

In which of the following stages of the development process is a team MOST likely to interview a potential user of an app?

A. investigating and reflecting
B. designing
C. prototyping
D. testing

investigating and reflecting

Which of the following best describes the purpose of a design specification?
A. Tracking errors that arise through user testing
B. Documenting comments that will need to be added to a program
C. Describing the requirements for how a program will work or users will interact with it
D. Listing detailed questions that will be asked of users during interviews

Describing the requirements for how a program will work or users will interact with it

Which of the following BEST describes the differences between sequential and event-driven programming?
A. In sequential programming commands run one at a time. In event-driven programming all commands run at the same time.
B. In sequential programming commands run faster than in event-driven programming.
C. In sequential programming each command is run many times in sequence. In event-driven programming all commands are run a single time as an event.
D. In sequential programming commands run in the order they are written. In event-driven programming some commands run in response to user interactions or other events.

. In sequential programming commands run in the order they are written. In event-driven programming some commands run in response to user interactions or other events.

Which of the following is NOT a reason to include comments in programs
A. Comments help the computer decide whether certain components of a program are important.
B. Comments help programmers debug issues in their own code
C. Comments help document how code was written for other programmers to use
D. Comments enable programmers to track their work throughout the development process

Comments help the computer decide whether certain components of a program are important.
