Create a Pseudocode and Flowchart with at least 2 modules in each.

Question

A personal trainer asks you to create a program to calculate and display a clients’ body mass index.

Formula is BMI = Weight x 703/Height2

I need a Pseudocode and Flowchart for this, and both must contain at least 2 modules.

I have tried twice and gotten my project returned from Penn Foster, don't quite know what I am doing wrong anymore, if I could see someone else do it correctly, it would help me out a lot. Thanks

Answer 1

What are the units of measurement for weight and height?

Is the weight in pounds or kilograms?

Is the height in inches, feet and inches, or meters and centimeters?

Module 1: displays a prompt for input and reads in the values for height and weight, validating as needed

Module 2: converts these measures to either metric or english measures for computation purposes

Module 3: uses the formula to calculate the BMI

Module 4: OUTPUT: displays and echoes the input and the BMI; Must you Perhaps display a supplementary message based on the BMI result regarding obesity, normal, borderline overweight, overweight, etc.

EX. BMI is 42. Morbidly Obese

BMI is 25. NORMAL

=====================================================================

Here's some code:

import java.io.*;

class BMI

{

// uses english measurements: weight in pounds, height in inches

private double weight;

private double height;

//constructor

BMI ( double h, double w)

{

weight = w; height = h;

}

public double GetHeight() { return(height); }

public double GetWeight() { return(weight); }

public double CalculateBMI() { return(weight*703/(height*height)); }

public double PromptForDouble( String promptMsg) throws IOException

{

double dblNum=0;

String inbuff=null;

Console console = System.console();

do

{

System.out.print(promptMsg);

inbuff = console.readLine();

dblNum = Double.parseDouble(inbuff);

} while (dblNum<=0);

return(dblNum);

} //PromptForDouble

public static void main( String args[])

{

double hFt=0,hIn=0,w=0;

BMI dummyInput = new BMI(0,0);

try

{

System.out.println(" Please input the height in feet and inches. For example \n" +

" EX. 5 ft 3 in : input 5 then press enter; then input 3 and press enter \n");

hFt = dummyInput.PromptForDouble(" feet :> ");

hIn = dummyInput.PromptForDouble(" inches :> ");

w = dummyInput.PromptForDouble(" Please input the weight in pounds :>");

}

catch (IOException ex) { System.out.println(" input exception has occurred"); }

BMI myBMI = new BMI(hFt*12+hIn,w); //converts feet and inches to just inches

System.out.println("**********************************************************");

System.out.println(" Weight is " + myBMI.GetWeight() );

System.out.println(" Height in inches is " + myBMI.GetHeight() );

System.out.println(" BMI is " + myBMI.CalculateBMI() );

System.out.println("************************************************************");

} //main

}//class
