//
// Author:    	 Amy Yurksaitis
//
// Instructor:   Dr. Wang
//
// Goal:         To be able to input positive natural numbers and to be able to
//		 output to the screen the largest number entered and to average
//		 of the inputted numbers.
//               
// Compile:      g++ homework1.cpp -o homework1.out
// Run:          ./homework1.out
