//      Author:         Benjamin Freeman
//      Instructor:     Dr. John Wang
//      Due date:       Wed., Feb. 6, 2008
//      Compilation:    g++ assign1b.cpp -o assign1b.out
//      Execution:      ./assign1b.out
//
//      Goal: This program will use arrays to calculate the average of a group of numbers
//      and output the results as well as the largest number and smallest number.
