Answer 3

10

Question 4

Which of the following is an example of an infinite loop?

A) While 1 > 2
B) While 2 < 1
C) While 1 == 1
D) Loop 1000 times times
E) None of these

Question 5

The While instruction can be used to test the value of an object's property.

Question 6

The following loop would execute how many times? Loop index from 0 up to (but not including) 3 times incrementing by 1

A) 1
B) 2
C) 3
D) 4
E) None of these

Question 7

Which type of structure is used to execute the same set instructions more than once?

A) Decision structure
B) Sequence structure
C) Repetition structure
D) Do together structure
E) None of these

Question 8

A(n) ___________________ loop will repeat an unlimited number of times.

Question 9

The While instruction is a posttest loop.

Question 10

Because the condition is tested before the loop is repeated, what is another term for the While instruction?

A) Counter-controlled loop
B) Infinite loop
C) Posttest loop
D) Pretest loop
E) None of these

Question 11

The ___________________ instruction causes a set of instructions to execute as long as a specified Boolean expression is true.

Question 12

This is the type of variable that the Loop instruction uses internally.

A) Register
B) Counter
C) Matrix
D) Address
E) None of these

Question 13

Which type of instruction will cause a set of instructions to execute as long as a specified Boolean expression is true?

A) If/Else
B) Loop
C) Repeat
D) While
E) None of these

Question 14

The While instruction is also called a(n) ___________________ loop because the condition is tested before the loop is repeated.

Question 15

Question 16

The following loop would execute how many times? Loop 1 times times

A) 1
B) 2
C) 3
D) 4
E) None of these

Question 17

You can use a variable or a function call to specify the number of repetitions that a loop will perform.

A) 1
B) 2
C) 3
D) 4
E) None of these

Question 20

The ___________________ instruction causes a set of instructions to execute a certain number of times.
