Exercise

The formula for converting a Fahrenheit temperature (F) to Celsius (C) is

C = (F — 32) * 5 / 9

Write a program to allow a user to enter a Fahrenheit temperature, convert the temperature to Celsius and print out the result of the conversion.

Test your program four times, ehtering temperatures of 212, 89.5, 32, -40

At what temperature are the Fahrenheit and Celsius temperatures the same value?
