NAME
clock - Determine processor time
SYNOPSIS
#include <time.h>
clock_t clock(void);
DESCRIPTION
The

function returns an approximation of processor time used by the program.

clock_t;
to get the number of seconds used, divide by
CLOCKS_PER_SEC.

The C standard allows for arbitrary values at the start of the program; take
the difference between the value returned from a call to
