AP CSP Semester Exam Review

Front

Any programming language that lets users create programs by manipulating “blocks” or graphical programming elements, rather than writing code using text.

Back

Block-based programming language

Answer explanation

The question describes a programming language that uses visual elements instead of text. The correct answer, 'Block-based programming language', specifically refers to this type of programming, making it the best choice.

Front

A sequence of steps, written in a programming language, that can be followed to solve a problem, especially by a computer.

Back

Computer Program

Answer explanation

A 'Computer Program' is a sequence of steps written in a programming language that a computer follows to solve a problem. An 'Algorithm' is a part of this, but the complete solution is best described as a 'Computer Program'.

Front

An error in a program that prevents the program from running as expected

Back

Bug

Answer explanation

A 'Bug' refers to an error in a program that causes it to malfunction or not run as intended. This term is widely used in software development to describe issues that need fixing.

Front

Statements that should only run upon a specific user action should be placed

Back

within an onEvent programming statement

Answer explanation

Statements that should run on specific user actions must be placed within an onEvent programming statement, as this structure allows the program to respond directly to user interactions.

Front

Finding and fixing problems in an algorithm or program

Back

Debugging

Answer explanation

Debugging is the process of finding and fixing problems in an algorithm or program. It involves identifying errors and correcting them to ensure the program runs as intended.

Front

The program above is run. Then the user clicks the "blueButton" button ONCE. What will be displayed in the console? Options: "1", "2", "3", "1", "3", "2", "2", "1", "3", "1", "3", "2"

Back

"1"
"3"
"2"

Answer explanation

When the user clicks the 'blueButton', it triggers a sequence that first logs '1', then '3', and finally '2' to the console. Therefore, the correct output is '1', '3', '2'.

Front

What color is blueButton after the code above runs? Options: blue, red, green, yellow

Back

green

Answer explanation

The code likely changes the color of blueButton to green. Therefore, after execution, blueButton is green.

Front

What color is redButton after the code above runs?

Back

yellow

Answer explanation

The code likely changes the color of redButton to yellow. Therefore, after the code runs, redButton is yellow.

Front

The program above is run. What color is blueButton if the user DOES NOT click blueButton?

Back

red

Answer explanation

If the user does not click blueButton, it defaults to red. The program likely changes the button color based on user interaction, and since there was no click, blueButton remains red.

Front

What will the console log say when this program is run?
Options:
"Starting my program!"
"You clicked the button!"
"Ending my program!"
,
"Starting my program!"
"Ending my program!"
"You clicked the button!"
,
"You clicked the button!"
"Starting my program!"
"Ending my program!"
,
"You clicked the button!"
"Ending my program!"
"Starting my program!"

Back

"Starting my program!"
"Ending my program!"
"You clicked the button!"

Answer explanation

The program starts by logging 'Starting my program!'. When the button is clicked, it logs 'You clicked the button!'. Finally, it logs 'Ending my program!'. Thus, the correct sequence is 'Starting my program!', 'Ending my program!', 'You clicked the button!'.
