//  Programmer:    John Puckett
//  OS:            Windows XP Professional
//  System:        Pentium 4 2.4Ghz, 1 GB Memory

//
//  Purpose
//  This program reads a list of student names and items from two input files 
//  creates 2 arrays from the data, then uses another input file to run different
//  algorithms on the arrays 
//
//  The program then writes the given commands and the results to
//	an output file
