/**
* Miss Manners Data Generator
*
* The purpose of this program is to generate a file of make statements that can
* be used as an input data set for the Miss Manners OPS5c program.
*
* All input to this program will be interactively obtained from the user. The
* file of make statements will be written to file manners.dat. The user
* specifies how many guests there will be. Each guest's name will be a unique
* integer. Each guest is assigned a sex at random. The user can specify the
* total number of hobbies it is possible for a guest to have, and a lower limit
* of the number of hobbies for a guest.
*
* For instance, if the user chooses 10 hobbies and a lower limit of 3 hobbies,
* each guest will have between 3 and 10 hobbies. The hobbies will be designated
* with an integer. Finally, the user can specify the number of seats available.
*
* The sex of the guests is assigned so that approximately half of the guests
* are male and half are female.
*
* This is based on the work of Tim Grose.
