need to include arrays

and if statements:

less than 15 very severely under weight

between 15 and 16 severely under weight

between 16 and 18.5 underweight

display message outside main

Answer 1

#include <iostream>

using namespace std;

double getBMI(double w, double h){
   return (w/(h*h));
}

int main()
{
   double w,h,bmi;
   
   cout<<"Enter weight: ";
   cin>>w;
   cout<<"Enter height: ";
   cin>>h;
   bmi = getBMI(w,h);
   cout<<"BMI = "<<bmi;
   cout<<endl;
   if(bmi < 15){
       cout<<("very severely under weight");
   } else if(bmi <= 16) {
       cout<<("severely under weight");
   } else if (bmi < 18.5) {
        cout<<("underweight");
    } else if (bmi < 25) {
        cout<<("healthy");
    } else if (bmi < 30) {
        cout<<("overweight");
    } else {
        cout<<("obese");
    }
    cout<<endl;
   return 0;
}
