In this question part, you will develop an algorithm which performs nutritional calculations by estimating total calories in order to assist users in managing their intake of calories. You should read the question all the way through before you start, to make sure that you understand the scenario. Background to the problem: A nutritional app assists users in assessing their dietary habits. For the purpose of evaluation, the app asks the members to report how many fat grams and how many carbohydrate grams they consume per day. To help users manage their calorie budgets more effectively, the app calculates the total calories derived from fat and carbohydrates, rounded to the nearest calorie. The problem: The purpose of this question is to write a program that will perform these nutritional calculations. Specifically, you will produce an estimate of the total calories as follows: calestimated = 1.01XYZ × caltotal = 1.01XYZ × (calfat + calcarb) The number of calories resulting from the fat are calculated by multiplying the fat grams by 9. calfat = fatgr x 9 Similarly, the number of calories that result from the carbohydrates are calculated as the carbohydrates grams multiplied by 4. calcarb = carbgr x 4 Your individual number is tied to the total calories so that there is some margin of error in the estimates. For example, if a member reported fatgr = 150 of fat and carbgr = 300 of carbohydrates on a day and the individual number is 1.01123 then: calestimated = 1.01123 × (150 × 9 + 300 × 4) calestimated = 2579 calories (rounded to the nearest calorie)
