    help with clock()

    I just want a program to be in an infinite loop but only do part of the code once a certain amount of time has elapsed.

    I've tried using clock() but can't get it to work. Is the clock reset everytime in a while() loop?

    Here's my code so far. I try to print the "duration" everytime through the loop but it's always 0.000000000.

    #include <time.h>
    int i = 0;
    clock_t start, finish, current;
    double	duration;
    int main(){
    	start = clock();
    	duration = (double) (current - start) / CLOCKS_PER_SEC;
    	printf("Time elapsed = %.10f\n", duration);
    	if (duration >= 5){
    	printf("5 Seconds is UP\n");
    	return 0;

    This is similar.
    7. It is easier to write an incorrect program than understand a correct one.
    40. There are two ways to write error-free programs; only the third one works.*
