Re: [Dev-C++] (no subject)

[Per W. <pw...@ia...>]

You have forgotten then end brace for your for() statement.

Note that you shouldn't use the for statement like that, since you don't
want to run it for 20 times, but until you have 20 accepted numbers. If a
user enters an incorrect number, the for loop should run for more than 20
times. With your current structure, you do one retry if the entered number
iswrong - however, you don't make a new check that the number is ok. If
you instead did the i++ increment only when you are satisfied with the
number, you may run the for loop as many times as is needed.

You should add a new loop (for j = 0; j < i; j++) to verify that the
entered number isn't a duplicate value.

By the way: Please specify a subject when you mail to this list.
