Consider the following code segment.

int k = 35;

while (k >= 0)

{

System.out.println("X");

k -= 5;

}

How many times will the string "X" be printed as a result of executing the code segment?

• 1

  A

• 7

  B

• 8

  C

• 35

  D

• More than 35 times, because the code segment will cause an infinite loop.

  E

• ______________________________________________________________________________________

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

  int x = 100;

  int total = 0;

  while( /* missing code */ )

  {

  total = total + x;

  x = x - 10;

  }

  Which of the following can be used as a replacement for /* missing code */ so that the code segment works as intended?

• x < 100

  A

• x <= 100

  B

• x > 10

  C

• x >= 10

  D

• x != 10

  E

• Consider the following code segment.

  for (int i = 0; i < 5; i++) // Line 1

  {

  for (int j = 0; j < 5; j++)

  {

  int k = i + j;

  System.out.print(k + " ");

  }

  }

  Which of the following best describes the result of changing i < 5 to i > 5 in line 1?

• The numbers will be printed in the reverse order as they were in the original code segment because the outer loop will occur in reverse order.

  A

• Five additional values will be printed because the outer for loop will iterate one additional time.

  B

• An infinite loop will occur because the termination condition of the loop will never be reached.

  C

• There will be no change to the program output.

  D

• Nothing will be printed because the body of the outer for loop will not execute at all.

  E

• ________________________________________________________________________________________________

• Consider the following code segment.

  int a = 1;

  while (a <= 2)

  {

  int c = 1;

  while (/* missing condition */)

  {

  System.out.print("*");

  c++;

  }

  a++;

  }

  The code segment is intended to print "******". Which of the following can be used to replace /* missing condition */ so that the code segment works as intended?

• c <= 2

  A

• c < 3

  B

• c <= 3

  C

• c > 2

  D

• c >= 3
