Write a program that calculates the energy needed to heat water from an initial temperature to a final temperature. Your program should prompt the user to enter the amount of water in kilograms and the initial and final temperature of the water. The formula to compute the energy is
 
Q=M×(finaltemperature−initial temperature)×4184
 
where the weight of water in kilograms, temperatures are in degrees Celsius, and energy is measured in joules.
