Arduino - do…while loop

The do…while loop is similar to the while loop. In the while loop, the loop-continuation condition is tested at the beginning of the loop before performed the body of the loop. The do…while statement tests the loop-continuation condition after performed the loop body. Therefore, the loop body will be executed at least once.

When a do…while terminates, execution continues with the statement after the while clause. It is not necessary to use braces in the do…while statement if there is only one statement in the body. However, the braces are usually included to avoid confusion between the while and do…while statements.
