Repeats a statement or group of statements while a given condition is true. It tests the condition before executing the loop body.

Executes a sequence of statements multiple times and abbreviates the code that manages the loop variable.

You can use one or more loops inside any another loop.

Terminates the loop statement and transfers execution to the statement immediately following the loop.

Causes the loop to skip the remainder of its body and immediately retest its condition prior to reiterating.
