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

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

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

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

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

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

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

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

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

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

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

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

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

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.

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

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

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

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

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

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

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

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

To ________ a variable means to decrease its value.

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

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

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

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

Which of these are posttest loops?

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

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