Create a BMI calculator applications that reads the user's weight in kilograms and height in meters, then calculates and displays the user's body mass index.Also, the application should display the following information from the Department of Health and Human Services, so the user can evaluate his/her BMI:
BMI Values
Underweight: less that 18.5
Normal: between 18.5 and 24.9
Overweight: between 25 and 29.9
Obese: 30 or greater


Formula for calculating BMI are
BMI = weightInKilograms
heightInMeters x heightInMeters

The program is to be written in C++ langauge.I need some help, urgently. Homework is due tomorrowevening.

Answer 1

Here is the Java code for Calculating BMI ..
//Importing packages
import java.util.*;//for Sacnner
import java.text.*;//NumberFormat
//Class
public class BMIDemo
{
//Main method
public static void main(String args[])
{
//Scanner object for input
Scanner scan=new Scanner(System.in);
//for formatting number
NumberFormat formatter=new DecimalFormat("#0.00");
//Declaring variables for height and weight
double height,weight;
//prompting for input
System.out.print("Enter Height in Meters : ");
height=scan.nextDouble();
System.out.print("Enter Weight in Kilograms : ");
weight=scan.nextDouble();
double BMI;
//Calculating BMI
BMI=weight/(height*height);
//Displaying BMI Basic values
System.out.println("nYour Body Mass Index is :"+formatter.format(BMI));
System.out.println("nBMI VALUES");
System.out.println("Underweight: less than 18.5");
System.out.println("Normal: Between 18.5 and 24.9");
System.out.println("Overweight: between 25 29.9");
System.out.println("Obese: 30 or greater");
}
}
