Programming Logic and Design Assignment
A man named John Raymond is so pleased with the program you created for his clients that he refers you to his coworker, a nutritionist in the same fitness facility. The nutritionist would like you to create a program that calculates fat grams and calories.
Design a program that asks 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 is 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 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.
- Create the pseudo-code for this program
- Create a flowchart for this program
Module main() Declare String doAnother Do Call getFatcalories() Display "Do you have another item? (Enter y for yes.)" Input doAnother While doAnother == "y" OR doAnother == "Y" End Module Module getFatcalories() Declare Real fatgram, calories,fatcalories Display "Enter number of fat grams." Input fatgram While fatgram < 0 Display "Number of fat grams cannot be negative. Please" Display "enter the correct number of fat grams." Input fatgram End While Display "Enter calories" Input calories While calories < 0 Display "The calories cannot be negative. Please" Display "enter the correct calories." Input calories End While While calories > fatgram*9 Display "The calories cannot be more than 9 times fatgrams. Please" Display "enter the correct calories." Input calories End While Set fatcalories = (fatgram*9) / calories Display "The percentage of calories that come from fat is $", fatcalories While fatcalories<30% Display "This is low fat food" End While End Module
