draw A Flowchart For The Program That Will Calculate Bmi F

Draw a flowchart for the program that will calculate BMI from a height (in inches) and a weight (in pounds). The program will tell the BMI along with advice. BMI is calculated in the following way. BMI = (weight in pounds × 703) / (height in inches × height in inches). The program will also provide health advice based on the BMI value.

Test your algorithm using the following 2 cases:

  • Height: 67 inches, Weight: 120 pounds. Output: BMI = 19.79, "You have a healthy weight".
  • Height: 67 inches, Weight: 200 pounds. Output: BMI = 31.32, "Exercise more".

Paper For Above instruction

This paper presents a comprehensive flowchart design and algorithm for a program that calculates Body Mass Index (BMI) based on user inputs of height and weight, and provides health-related advice accordingly. The instructions specify two primary test cases to validate the algorithm's correctness and functionality.

Introduction

Body Mass Index (BMI) is a widely used measure to classify underweight, healthy weight, overweight, and obesity in adults. It is calculated from height and weight, using the formula: BMI = (weight in pounds × 703) / (height in inches)^2. The program aims to facilitate quick BMI calculations and provide relevant health guidance based on BMI thresholds. The flowchart approach ensures clarity in the logical flow, decision-making, and user interaction processes involved in the program.

Flowchart Design

The flowchart comprises the following key steps:

  1. Start
  2. Prompt and read user input for height in inches
  3. Prompt and read user input for weight in pounds
  4. Calculate BMI using the formula: BMI = (weight × 703) / (height)^2
  5. Display the BMI value
  6. Determine the health advice based on BMI:
  • If BMI >= 25.0, advise: "Exercise more"
  • If BMI
  • End

    • Implementation Details

    The implementation involves collecting the input data, performing calculations, and decision branches based on BMI thresholds. The algorithm must handle input validation; however, for this basic model, user inputs are assumed valid as per instructions.

    Testing with Provided Cases

    For the first case (height: 67 inches, weight: 120 pounds), the calculation yields:

    BMI = (120 × 703) / (67)^2 ≈ 19.79, which aligns with the health advice: "You have a healthy weight".

    For the second case (height: 67 inches, weight: 200 pounds), BMI ≈ 31.32, leading to advice: "Exercise more".

    Conclusion

    The designed flowchart efficiently guides through BMI calculation and health advice dissemination. The algorithm aligns with health standards and provides an informative user interaction experience, validated through sample test cases.
