So, you need to implement following functions in your program. Welcome to the Conversion Program 1. Fahrenheit to Celsius Miles to kilometers 3. 2. Liters to Gallons 4. Exit from the program You should implement this program using functions and your program need to have following functions void displayMenu() double fahrenheitToCilsuis(double fTemp) double milesToKilometers(double miles) double litersToGallons(doube liters)
