A nutritionist who works for a fitness club helps members by evaluating their diets. As part of her evaluation, she asks members for the number of fat grams and carbohydrate grams that they consumed in a day. Then, she calculates the number of calories that result from the fat, using the following formula: calories from fat = fat grams X 9 Next, she calculates the number of calories that result from the carbohydrates, using the following formula: calories from carbs = carb grams X 4 The nutritionist asks you to write a program that will make these calculations.
