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.

Exercise

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.

 

Question

1. Create the pseudo-code for this program
2. Create a flowchart for this program

Solution(Flowchart)

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
