/* boucingball4.cpp calculates and displays the rebound heights 
 * of a dropped ball.
 *
 * Input:  a real height from which a ball is dropped.
 * Output: for each rebound of the ball from the pavement below:
 *            the number of the rebound and
 *            the height of that rebound
 *         assuming that the height of each rebound 
 *         is one-half the previous height
