Validate the input as follows:
- Make sure the number of fat grams and calories is not less than 0.
- According to nutritional formulas, the number of calories cannot exceed fat grams X 9. Make sure that the number of calories entered is not greater than fat grams X 9.
Once correct data has been entered, the program should calculate and display the percentage of calories that come from fat. Use the following formula:
Some nutritionists classify a food as “low fat” if less than 30 percent of its calories come from fat. If the results of this formula are less than 0.3, the program should display a message indicating the food is low in fat.

ANSWER IN PSEUDOCODE
(Science: calculating energy) 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 temperatures of the water. The formula to compute the energy is Q = M * (finalTemperature – initialTemperature) * 4184 where M is the weight of water in kilograms, temperatures are in degrees Celsius, and energy Q is measured in joules.
