CSA Unit4 Lucky Test

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

• The variable prod is incorrectly initialized.

• The while condition always evaluates to false.

• The while condition always evaluates to true.

• The negative number entered to signal no more input is included in the product.

• If the user enters a zero, the computation of the product will be terminated prematurely.

• 1

• 3

• 5

• 7

• 8

What is printed as a result of executing this code segment?

• 1

• 2

• 3

• 5

• 6

Which of the following best explains how the output changes from code segment I to code segment II?

• Both code segments produce the same output, because they both iterate four times.

• Both code segments produce the same output, because they both iterate five times.

• Code segment I prints more values than code segment II does, because it iterates for one additional value of k.

• Code segment II prints more values than code segment I, because it iterates for one additional value of k.

• The code segments print the same values but in a different order, because code segment I iterates from 1 to 5 and code segment II iterates from 5 to 1.

Which of the following best describes the value returned from a call to doWhat ?

• num

• The sum of all integers between 1 and num, inclusive

• The sum of all even integers between 1 and num, inclusive

• The sum of all odd integers between 1 and num, inclusive

• No value is returned because of an infinite loop.

Consider the following method. What value is returned as a result of the call getTheResult(8) ?

• 40320

• The number of times the string check occurs in str

• The index of the first occurrence of check inside str

• The index of the last occurrence of check inside str

• The number of substrings in str with the same length as check

• The number of substrings in str that do not match check
