The conditions that control a loop repetition are Boolean expressions.

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

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

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

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

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

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

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

Modules can be called from statements in the body of any loop.

Any loop that can be written as a Do-While loop can also be written as a While loop.

In the For statement, you can only use positive integers as step values.

The While loop will never execute if its condition is true to start with.
