Write a program that will calculate the user's carbon footprint for the year. You should have a different function for each component of the footprint. The user will input the several parts of their footprint: how the house is heated (wood, gas, propane, or electricity), car fuel (no car, electric, gas, diesel), then the relevant information. The relevant information needed will vary depending on the user's answer, and the calculations of the total carbon footprint will also vary. This is a complex problem - it is best to work on it one function at a time, see if it is working, and then move forward. You will need many different if statements. Write at least two tests for each function.
