set the variable count_down_time_in_secs in seconds for desired count down time.
The Code is self explanatory.
1 minute = 60 secs
5 minutes = 60x5 secs
30 minutes =60x30 secs
1 hour = 60x60 secs

#include <stdio.h>
#include <time.h>

int main ()
	unsigned int x_hours=0;
	unsigned int x_minutes=0;
	unsigned int x_seconds=0;
	unsigned int x_milliseconds=0;
	unsigned int totaltime=0,count_down_time_in_secs=0,time_left=0;
	clock_t x_startTime,x_countTime;
	count_down_time_in_secs=10;  // 1 minute is 60, 1 hour is 3600

    x_startTime=clock();  // start clock
    time_left=count_down_time_in_secs-x_seconds;   // update timer

	while (time_left>0) 
		x_countTime=clock(); // update timer difference

		time_left=count_down_time_in_secs-x_seconds; // subtract to get difference 

		printf( "\nYou have %d seconds left ( %d ) count down timer by TopCoder 

	printf( "\n\n\nTime's out\n\n\n");
return 0;

About me:
I attended programming School and I have a degree in three programming languages.
C/C++, Visual Basic and Java. So i know i can code. And there is a diploma hanging on my wall to prove it.
I am a professional, I've gotten paid to teach coding. I am roughly 20 years old and i have been a teacher's assistant in programming ,
i have held a lecture in Visual basic programming. I have also coached students in C++, Java and Visual basic.

In my spare time i do enjoy developing computer games, and i am developing a rather simple flight simulator game

I've written about a dozen small simple applications and games.
