main.cpp

//----- Program History -----//
// Version 1.0 created 30 October 2009
// Originally created for CSS390 in an attempt to derive patterns from
// from homophonic ciphertext provided by "I.M. Voynich"

/* 08 Nov 2009: Changed code to be more generalized for files.
 *              Now using dymanic arrays versus mutliple static arrays */
/* 08 Nov 2009: Parsed work into new .h and new .cpp file named "Driver" */
/* 09 Nov 2009: Added more code for newest ciphertext block */
/* 20 Nov 2009: Separated char and int functionality into different drivers */

// Version 2.0 created 25 November 2009
// Created to streamline processes in ver1.0

// Version 3.0 created 30 November 2009
/* 30 Nov 2009: Splits functionality into two programs: one for char ciphertext
 *              and one for int ciphertext */
/* 30 Nov 2009: Added new "CipherList" class to handle linked list of nodes
 *              with pointers to integers for digraphs and trigraphs appearing
 *              in the ciphertext block */
