// Assignment: Module 2 Semester Project
// Description: My Objective this section will be to add a Switch
//              statement Menu to prompt the user to make a selection.
//              The selection choice that they make will determine the
//              functionality the program will execute.

#include<iostream>
// added iomanip //
#include<iomanip>
// added cmath for Sem. 2 Project //
