Hallo to all.

I'm trying to write a console program doing the followings:

Code:
int main(void)
{
   int hour, min;
   printf("Set the time (like 12:00)");
   scanf("%d:%d", &hour, &min);
}
After that, i would like to compare the given time with calendar time and when the calendar time reaches the given time, then a function to be executed.
My main problem is to convert given time to a type in order to compare with calendar time.

Thanks in advance
Saik
