How To Make A Pseudocode And Flowchart For Food Nutrition Program

I am trying to find some help as to how to make a pseudocode and flowchart to design a program that asks for fat grams and calories in a food item. Validate input as follows: -Number of fat grams and calories aren't less than 0 -Number of calories aren't greater than fat grams 9. Once correct data is entered, program should calculate and display percent of calories from fat. Use formula: Percentage of calories from fat = (fat grams 9) / calories. If the results are less than 0.3, the program should display a message saying that the food is low in fat. Please help! Thank you!

Introduction

This guide provides a comprehensive approach to designing a program that determines the percentage of calories from fat in a food item. It includes detailed pseudocode and flowchart descriptions optimized for clarity, correctness, and ease of implementation for beginners and experienced programmers alike.

Pseudocode for the Program

The pseudocode outlines the logical flow, validation, calculation, and output processes necessary to meet the requirements.

BEGIN


PROMPT user for fat grams


READ fat_grams


PROMPT user for calories


READ calories


WHILE (fat_grams  fat_grams * 9)


DISPLAY "Invalid input. Please enter valid data:"


PROMPT user for fat grams


READ fat_grams


PROMPT user for calories


READ calories


END WHILE


CALCULATE total_calories_from_fat = fat_grams * 9


CALCULATE percentage_fat = total_calories_from_fat / calories


DISPLAY "Percentage of calories from fat: " + (percentage_fat * 100) + "%"


IF percentage_fat 

DISPLAY "This food is low in fat."


END IF


END

Flowchart Explanation

The flowchart visually represents the decision-making process, including input validation, calculations, and outputs.

  1. Start: Begin the program.
  2. Input fat grams and calories: Prompt user and read inputs.
  3. Validate inputs: Check if fat grams or calories are less than 0, or if calories exceed fat grams * 9.
  • If invalid, display error message and return to input step.
  • If valid, proceed.
  • Calculate total calories from fat: Multiply fat grams by 9.
  • Calculate percentage of calories from fat: Divide total calories from fat by total calories.
  • Display percentage: Show the calculated percentage.
  • Check if percentage : If true, display that the food is low in fat.
  • End: Terminate the program.

    • Conclusion

    This pseudocode and flowchart provide the foundational steps to create a nutrition calculator program. They ensure input validation, accurate computation, and meaningful user feedback, aligning with nutritional standards and programming logic.
