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?
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.
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.
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).
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
Body of the loop
The statements that appear between the While and the End While clauses are called the ________.
False
T/F — In a For loop, the programmer should know the exact number of iterations the loop must perform before writing the code.
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
