Answer:Design a program that asks the user for the number of fat grams and calories in a food item. Validate the input as follows.
Make sure the number of fat grams and calories are not less than 0.
According to nutritional formulas, the number of calories cannot exceed fat grams * 9. Make sure that the number of calories entered is not greater than fat grams * 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:
Percentage of calories from fat=( Fat grams * 9) / Calories
Some nutritionists classify food as “ low fat” if less than 30percent 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.
