Is there any function in std. C to convert seconds into hour, min and sec. ?
Lets say the following code takes 129 seconds, how do i get components of 
time in "hour min and second" format? Is there any std. library function to 
do this?
it should give "0 hrs 2 min 9 sec"


/* The following code only prints elapsed time in seconds */
#include<stdio.h>
#include<limits.h>
#include<time.h>

int main(void)
{
 time_t t1, t2;
 unsigned int i,j, k;

 t1 = time(NULL);

 /* some code to timed here.... */
 /* ..... */
 for(i = 0; i < ~0; i++);
 /* ... end of processing ... */

 t2 = time(NULL);
 k = difftime(t2, t1);
 printf("Time Elapsed = %d seconds\n", k);

 return 0;
}

% is the infix modulus operator.
If you cant now get the answer, give up programming.

try (untested):

#include <stdlib.h>
#include <time.h>

long int      hrs, mins, secs;
ldiv_t        result;
time_t        t1, t2;

.....
   t1 = time(NULL);
   ....
   t2 = time(NULL);
   secs = difftime(t2, t1);
   result = ldiv(secs, 60);
   secs = result.rem;
   mins = result.quot;
   mins = ldiv(mins, 60);
   mins = result.rem;
   hrs  = result.quot;

No, but it sounds like a perfectly wonderful routine to add to your
personal library of routines.

Then you'd have the added advantage of learning how to maintain an
object library in C.

Or you could take the cheap way out and make it a standalone source
file and use a makefile to include it for the program.  Assuming
'make' is supported on your platform, of course.

Thanks for the tip.

I was wondering why the formatting was sometimes quite stupid.  Hadn't
looked into it enough to hit critical mass for intuitive resolution.
Figured it was just another one of those things you live with in an
imperfect Internet world.
