Question: Suppose you need functions to convert temperatures between the Fahrenheit and Celsius scales. Here are three ways to do it.

a. Create two functions: f2c and c2f that each take a temperature as a double and return a double indicating the converted temperature.

b. Do as in part (a) except name the functions Fahrenheit To Celsius and Celsius To Fahrenheit.

c. Create just one convert Temperature (double temperature, int from Scale, in to Scale) function that takes three parameters: the temperature to be converted, the scale used by that temperature, and the scale to be used for the converted temperature. Which of those three approaches is most elegant? Explain. Suppose you are asked to include the Kelvin temperature scale as a third alternative, and so you need to write code that converts from any one of the three scales to any other of the three scales. Find the most elegant approach.
