C++ Neural Networks and Fuzzy Logic: Preface

Header File for C++ Program for Hopfield Network

Listing 4.1 contains Hop.h, the header file for the C++ program for the Hopfield network. The include files

listed in it are the stdio.h, iostream.h, and math.h. The iostream.h file contains the declarations and details of

the C++ streams for input and output. A network class and a neuron class, are declared in Hop.h. The data

members and member functions are declared within each class, and their accessibility is specified by the

keywords protected or public.
