// CS212 HW #1:  homework1b.cpp
//
// Due:          February 6, 2008
//
// 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 smallest  number entered and to average
//               of the inputted numbers, using arrays.
//
// Compile:      g++ homework1b.cpp -o homework1b.out
// Run:          ./homework1b.out
