AP Computer Science A Unit 4 Section 1 (While loops)

What, if anything, is printed as a result of executing the code segment?

• 21

• 161116

• 161161

• 16111621

• Nothing is printing because of an infinite loop.

What will be the value of count after executing the code segment?

• 6

• 5

• 4

• 1

• 0

This code segment is intended to store the sum of all multiples of 10 between 10 and 100, inclusive (10 + 20 + ... + 100), in the variable total.

What should /* missing code */ be?

• x < 100

• x <= 100

• x > 10

• x >= 10

• x != 10

This code is intended to print the sum of the digits in num. For example, when num is 12345, the code segment should print 15, which represents the sum 1 + 2 + 3 + 4 + 5.

What should /* missing loop header */ be?

• while (num > 0)

• while (num >= 0)

• while (num > 1)

• while (num > 2)

• while (num > sum)

What, if anything, is printed as a result of executing the code segment?

• 0

• 1

• 2

• 3

• Nothing is printed.
