// CS112 CS 1 Assignment 4 (i)
// Due: Monday, October 25, 2010
//
// File Name: assignment4a.cpp
// Author: Jennifer Whiley
// Instuctor: Dr. Wang
//
// Compile: g++ assignment4a.cpp
// Run: ./a.out
//
// Goal: The program will read three integers and output their root(s) to
//       one decimal place. The program will loop to allow user run the program
//       multiple times.
