Answer 2

#include<iostream>
using namespace std;

int main()
{
cout << "Enter weight in pounds:";
double weight;
cin >> weight;

cout << "Enter height in inches:";
double height;
cin >> height;

const double KILOGRAMS_PER_POUND = 0.45359237;
const double METERS_PER_INCH = 0.0254;

double weightInKilongrams = weight * KILOGRAMS_PER_POUND;
double heightInMeters = height * METERS_PER_INCH;
double bmi = weightInKilongrams /
(heightInMeters*heightInMeters);

cout << "BMI is" << bmi << endl;
if (bmi < 18.5)
cout << "Underweight" << endl;
else if (bmi < 25)
cout << "Normal" << endl;
else if (bmi < 30)
cout << "Overweight" << endl;
else
cout << "Obese" << endl;

return 0;
