You could check the time every iteration, although that seems kind of wasetful to be trying to break a while loop that way.

how can i say that
time_t a = 2:00:00;

You can't just do it that way. The problem with just specifying 2:00 is that you need to tell it 2:00 on which day.

Create a struct tm object and set the members to the exact time you want to stop at. When you have it set right, pass it to mktime(), and you'll get a time_t variable. Compare that to what you get from time() every iteration with the difftime() function, and you'll get the
difference in seconds between the two times.

It would seem a better way of doing this would be to create a separate thread that just sleeps until a given time and then sets a boolean flag that the other thread can check on whether to quit or not. This might be beyond the scope of your assignment, however.
