//      Instructor:     Dr. John Wang
//      Compilation:    vi hw1.cpp
//      Execution:      g++ hw1.cpp
//      Goal:           Write a program that prompts a message and lets the user//                      input natural numbers. The program will quit when a
//                      negative number is typed in. The program will output the//                      following results to the screen: average value (display //                      to one decimal place) and the largest number typed in.
//                      Don't use arrays for this program.
