Describing the requirements for how a program will work or users will interact with it
Listing detailed questions that will be asked of users during interviews
What is the primary role of a software requirement specification?
To provide a detailed list of all the programming languages used in the project
To outline the project timeline and milestones
To describe the functionalities, system behavior, and performance levels that the software product must fulfill

Australia, Germany, India
Australia, India
Germany
Australia, India, Germany
If the user clicks 3 times, what will print?
(a)
In (a) commands run in the order they are written
In (a) some commands run in response to user interactions or other events
Programmers use comments to:
debug issues in code
document how code was written for other programmers to use
decide which components are important to use
What is the purpose of an onEvent?
triggers code to run after user interacts with screen
always sets properties for the screen
never shows anything to the user
What is important in syntax?
parentheses
spelling
quotation marks
how fast you type it
In which of the following stages of the development process is a team MOST likely to interview a potential user of an app?
investigating and reflecting
designing
prototyping
testing
Which of the following best describes the purpose of a design specification?
Tracking errors that arise through user testing
Documenting comments that will need to be added to a program
Describing the requirements for how a program will work or users will interact with it
Listing detailed questions that will be asked of users during interviews
The following program is run. Then the user clicks the "topButton" button ONCE. What will be displayed in the console?
cat bird dog
dog cat bird
cat dog bird
bird cat dog
Which line of code in this program is MOST likely to result in an error?
Line 1
Line 2
Line 3
Line 4
The following program is run. Then the user clicks the "bottomButton" TWO TIMES. What will be displayed in the console?
aaa bbb ccc ddd
bbb ddd ccc ccc
bbb ddd aaa aaa
bbb ccc ccc ddd
Which of the following BEST describes the differences between sequential and event-driven programming?
In sequential programming commands run one at a time. In event-driven programming all commands run at the same time
In sequential programming commands run faster than in event-driven programming.
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.
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
Comments help the computer decide whether certain components of a program are important.
Comments help programmers debug issues in their own code
Comments help document how code was written for other programmers to use
Comments enable programmers to track their work throughout the development process
