 * odometer.c - rollover 2 digits
 *              like an odometer in 
 *              a car.
 *
 *              Revised to contain 6
 *              digits and rollover
 *              from 999999 to 000000
 *              but using nested if
 *              statements, trying to
 *              find alternate means
 *              of accomplishing this.
