// CS212 HW #2:  homework2.cpp
//
// Due:          February 13, 2008
//
// Author:       Amy Yurksaitis
//
// Instructor:   Dr. Wang
//
// Goal:         To write a program that allows the user to input student
//		 data such as; name, age, and test scores. Then the program
//               will output to the screen that information plus the
//		 students average, the class average,
//		 and the average age of the class
//
// Compile:      g++ homework2.cpp -o homework2.out
// Run:          ./homework2.out
