statement	Block of statements that is executed at least once and is re-executed each time the condition evaluates to true.
condition	Evaluated after each pass through the loop. If `condition` evaluates to true, the statements in the preceding block are re-executed. When `condition` evaluates to false, control passes to the statement following `do while`.
