Answer 1

#include <iostream>
using namespace std;
 
int main()    {
  double index, weight, weightInKilograms, height;
  double heightInMeters, heightSquared, kilogramsPerPound, metersPerInch;
 // initialize constants and variables   
    kilogramsPerPound = 0.45359237;
    metersPerInch = 0.0254;
// get user input values
   cout<<"Enter weight = ";
   cin>> weight;
   cout<<"Enter height = ";
   cin>> height;
// perform calculations

heightInMeters=height*metersPerInch;
weightInKilograms=weight*kilogramsPerPound ;
heightSquared= heightInMeters*heightInMeters;
index = weightInKilograms/heightSquared;
        
cout<<"index = "<<index<<endl;        

// decide index category
if(index<18.5)
   cout<<"You are underweight";
else if(index<25.0)
   cout<<"Your weight is normal";
else if(index<30.0)
   cout<<"Your weight is overweight";   
else
 cout<<"Your weight is obese";  

cout<<endl<<endl;
