// This program shows how "enum" type can be used as a part of a class.
// Key Points:  	1) "enum" data type.
//		2) You must insure being in the correct range; otherwise 
//		     logic errors occur.

// Note: 	The "char*" type used in the program can be read as the String type 
// 		described in your text book.
