For

Which loop statement does not contain an increment statement but automatically increments the counter at the end of each iteration?

Do-While and Do-Until

Which of these are posttest loops?

While and Do-While

Which pair of loops causes a statement or set of statements to repeat as long as a condition is true?

Running total

A loop that accumulates a total as it reads each number from a series is often said to keep a what?

Three

How many times will the following loop iterate? For j = 1 To 5 Step 2 Display j End For

One

How many times will the following loop iterate? Set k = 1 Do Display k Set k = k + 1 Until k > 1

Infinite

How many times will the following loop iterate? Set k = 1 While k < = 5 Display k End While

No iterations

How many times will the following loop iterate? Set k = 1 While k > 5 Display k End While

True

T/F — A While loop repeats infinitely when there is no statement inside the loop body that makes the test condition false.

True

T/F — A condition-controlled loop can be used to iterate the body of the loop a specific number of times.

False

T/F — A posttest loop does not perform any iteration if the Boolean expression is false to begin with.

True

T/F — Any loop that can be written as a Do-While loop can also be written as a While loop.

False

T/F — In a For loop, the programmer should know the exact number of iterations the loop must perform before writing the code.

decrement

To ________ a variable means to decrease its value.

Condition-controlled

What type of loop uses a Boolean expression to control the number of times that it repeats a statement or set of statements?

For

Which loop is specifically designed to initialize, test, and increment a counter variable?

False

T/F — In the For statement, you can only use positive integers as step values.

True

T/F — Modules can be called from statements in the body of any loop.

True

T/F — The While and For loops are considered pretest loops because they test the condition before processing the statement(s) in the loop body.

False

T/F — The While loop gets its name from the way it works: While a condition is false, do some task.

True

T/F — The While loop is known as a pretest loop, which means it tests its condition before performing an iteration.

False

T/F — The While loop will never execute if its condition is true to start with.

True

T/F — The conditions that control a loop repetition are Boolean expressions.

Sentinel

The ________ represents a special value that marks the end of a list of values.

Step amount

The amount by which the counter variable is incremented in a For loop is known as what?

count-controlled

The following is an example of what type of loop? For k = 7 To maxValue

Body of the loop

The statements that appear between the While and the End While clauses are called the ________.

Do-Until

Which loop repeats a statement or set of statements as long as the Boolean expression is false?

Repetition

Which structure causes a statement or set of statements to execute repeatedly?

Three

In a count-controlled loop, the counter performs ________ action(s).
