/********************************************************
 * guess -- a simple guessing game			*
 *							*
 * Usage:						*
 *	guess						*
 *							*
 *	A random number is chosen between 1 and 100.	*
 * 	The player is given a set of bounds and 	*
 *	must choose a number between them.		*
 *      If the player chooses the correct number he wins*
 *	Otherwise the bounds are adjusted to reflect	*
 *	the players guess and the game continues	*
 *							*
 * Restrictions:					*
 *	The random number is generated by the statment	*
 *	rand() % 100.  Because rand() returns a number	*
 *	0 <= rand() <= maxint  this slightly favors	*
 *	the lower numbers.				*
