// Exercise 10.11: TemperatureConverter.cpp
// Converts a degree amount from Celsius to Fahrenheit,
// or from Fahrenheit to Celsius.

#include <iomanip>  // required for parameterized stream manipulators 

using namespace std; // for accessing C++ Standard Library members

// function main begins program execution
