Bogar * Date: 8/3/99 * Section 101 * EMail: bogar@cs.umbc.edu * * This file contains some simple statistical * functions each written to handle two integers * as input. They are grouped together in this * file because they are related modules, all simple * statistical functions, and as such could be used * by any program that deals with simple statistics * involving only two integers. * * This file is meant to be compiled separately from * the main program. * * Functions in this file: * Sum (x, y) * Min (x, y) * Max (x, y) * Avg (x, y) * Dist (x, y) * *********************************************/ /*********************************** * All header files needed by the code * found in the functions defined * in this file.
