       cpu_time_used = ((double) (end - start)) / CLOCKS_PER_SEC;

}

if you are wondering why the time displayed is compiler specific instead of being processor specific the solution is here:
Applications should use sysconf(_SC_CLK_TCK) to determine the number of clock ticks per second as it may vary from system to system.

Your post has two flaws:
1) it assume the user is running *nix operating system. That may, or may not be correct.

2) Your post is irrelevent because it has nothing at all to do with using the clock() function.
