True/False: A posttest loop does not perform any iteration if the Boolean expression is false to begin with.

False

True/False: In a For loop, the programmer should know the exact number of iterations the loop must perform before writing the code.

False

True/False: In the For statement, you can only use positive integers as step values

False

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

False

True/False: The While loop will never execute if its condition is true to start with.

False

True/False: A While loop repeats infinitely when there is no statement inside the loop body that makes the test condition false.

True

True/False: A condition-controlled loop can be used to iterate the body of the loop a specific number of times.

True

True/False: Any loop that can be written as a Do-While loop can also be written as a While loop.

True

True/False: Modules can be called from statements in the body of any loop.

True

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

True

True/False: The While loop is known as a pretest loop, which means it tests its condition before performing an iteration.

True

True/False: The conditions that control a loop repetition are Boolean expressions.

True
