Loops (Nested too)

What does the following code print?

• 5 4 3 2 1

• -5 -4 -3 -2 -1

• -4 -3 -2 -1 0

• None of the above

Consider the following code segment. Which of the following can be used as a replacement for the missing loop header so that the loop prints out “0 2 4 6 8 10”?

• while (count == 10)

• while (count < 10)

• while (count <= 10)

• while (count > 10)

Consider the following code segment. What is count’s value after running this code segment?

• 0

• 1

• 16

• 6

What does the following code print?

for (int i = 3; i < 8; i++)

{

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

}

• 3 4 5 6 7 8

• 0 1 2 3 4 5 6 7 8

• 8 8 8 8 8

• 3 4 5 6 7

What does the following code print?

• 7 rows with 5 columns

• 7 rows with 4 columns

• 6 rows with 5 columns

• 6 rows with 4 columns

What does the following code print?

• A rectangle of 4 rows with 3 star per row.

• A rectangle of 5 rows with 3 stars per row.

• A rectangle of 4 rows with 1 star per row.

• The loops have errors.

What are the values of var1 and var2 when the code finishes executing?

• var1 = 1, var2 = 1

• var1 = 2, var2 = 0

• var1 = 3, var2 = -1

• var1 = 0, var2 = 2

• The loop will cause a run-time error with a division by zero.

Consider the following code segment. How many times is the string “Hi!” printed as a result of executing the code segment?

• 15

• 12

• 10

• 8
