Urgent answers design a program that asks for the number of fat grams and calories in food items. 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:

percentage of calories from fat=(fat grams x 9) ÷ calories

some nutritionist 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.
