AP CSA Unit 4 Review

Front

What will happen to the output of the code segment? Options: The output of the code segment will be unchanged. The string "Fun" will be printed more times because the outer loop will execute more times. The string "Fun" will be printed more times because the inner loop will execute more times in each iteration of the outer loop. The string "Fun" will be printed fewer times because the outer loop will execute fewer times. The string "Fun" will be printed fewer times because the inner loop will execute fewer times in each iteration of the outer loop.

Back

The string "Fun" will be printed more times because the outer loop will execute more times.

Front

Which of the following code segments could replace the while loop in the method digitSum without changing the value returned by the method? Options: I only, II only, III only, I and II, II and III

Back

III only

Front

Which of the following best explains how the difference in the two loop headers affects the output? Options: The output of the code segments is the same because the loops in each code segment terminate when i is 10. The output of the code segments is the same because the loops in both code segments iterate 10 times. The output of the code segments is different because code segment I iterates from i = 0 to i = 9 and code segment II iterates from i = 1 to i = 10. The output of the code segments is different because code segment I iterates from i = 0 to i = 10 and code segment II iterates from i = 1 to i = 11. Neither code segment produces output because both loop conditions are initially false.

Back

The output of the code segments is the same because the loops in both code segments iterate 10 times.
