AP Computer Science Principles Exam

Question 1

A team of students is developing a program together. One student frequently dismisses others' ideas without discussion, and progress slows. According to AP CSP, what is the most effective collaborative practice to improve their development process?

Have the most experienced student write all the code alone Stop discussing the design and immediately start coding to save time Solicit and incorporate feedback from multiple team members and consider different perspectives Assign blame for the slow progress before continuing

Correct Answer:

Solicit and incorporate feedback from multiple team members and consider different perspectives

Question 2

In an iterative and incremental development process, what is the recommended approach to building and improving a program over time?

Write the entire program at once and only test it after it is fully complete Plan the program completely on paper and never change the plan once coding begins Repeatedly design, implement, and test small pieces, refining the program through cycles of feedback Release the program to users before any testing is done

Correct Answer:

Repeatedly design, implement, and test small pieces, refining the program through cycles of feedback

Question 3

A program is intended to count the number of even values in a list, but it returns an incorrect count. The programmer adds statements to display intermediate values while the program runs. What debugging technique is this?

Refactoring the program into procedures Compressing the program's data Using print/display statements to trace program state and locate the error Adding more comments to the code

Correct Answer:

Using print/display statements to trace program state and locate the error

Question 4

Which of the following best describes a logic error in a program?

The program will not run because of a misspelled keyword The program cannot access the Internet The program runs but produces incorrect or unexpected results The program uses too much storage on the device

Correct Answer:

The program runs but produces incorrect or unexpected results

Question 5

A development team documents the purpose and function of each part of their program as they build it. Why is this documentation valuable during creative development?

It makes the program run faster It automatically removes all logic errors It helps collaborators and future developers understand, maintain, and modify the program It is required for the program to compile

Correct Answer:

It helps collaborators and future developers understand, maintain, and modify the program
