Question

Which loop iterates till the condition evaluates to true?
(a) while
(b) until
(c) for
(d) case

Answer 1

actually these loops works till the given expression becomes FALSE.
i am not aware of the until loop....
case is not a loop , but is a part of switch case , which when true executes a set of statements , till break is encountered. Somewhat like if-else but only useful for equality tests....
