Thread: about loops, i'm a n00b

hey,
i just got started on C and i already got into a problem with loops. this is what i wrote:

Code:

int main ()
{
        int days, pennies;
        {
        printf ("days of month: ");
        scanf ("%d", &days);
        } while (days <28 || days>31);

}

well and if i write any number between 28 and 32 then it passes on to the next step, but i want it to loop and say "days of month" again if writing anything that isn't 28-31 but i clearly failed on that one, cuz when i type in something that isn't between those numbers nothing happens.

all thanxxx for help.

It looks like you want to use a "do-while()" loop ... but you're missing the "do".

With a different indentation (more like what the program does) your program looks like this:

Code:

int main ()
{

        int days, pennies;

        {
              printf ("days of month: ");
              scanf ("%d", &days);
        }

        while (days <28 || days>31);

}

Your program is composed of 1 block and 1 (empty) loop. You probably wanted a "do ... while" loop.
