#include <stdio.h>

int main( void )

{

    double height, weight, bmi;

    int bmievalcode;

    while( 1 )

    {

        /* --> add code to input weight and height between here */

        scanf("%lf %lf\n" , &weight &height)

        bmi = weight * 703 / (height * height);

        /* <-- and here */

        /* --> add code to calculate bmi and bmievalcode between here */

        if (bmi <= 00.0){

            bmievalcode = -1;

        else if (bmi < 18.5)

            bmievalcode = 1;

        else if (bmi >= 18.5 && bmi < 25.0)

            bmievalcode = 2;

        else if (bmi >= 25.0 && bmi < 30.0)

            bmievalcode = 3;

        else (bmi >= 30)

            bmievalcode = 4;



        /* <-- and here */

        /*  bmievalcode:

        *  1 = underweight

        *  2 = normal

        *  3 = overweight

        *  4 = obese

        */

        /* --> add code to print bmi and bmievalcode between here */

        /* <-- and here */

    }

    while( 1 ) getchar( );

    return 0;

}

what is the printf that can show:
bmi = %lf, evaluation is underweight
                                      normal
                                      overweight
                                      obese

in one printf statement

The Body Mass Index (BMI) is a calculation used to categorize whether a person’s weight is at a healthy weight for a given height. The formula is as follows:                 bmi = kilograms / (meters2)                 where kilograms = person’s weight in kilograms, meters = person’s height in meters BMI is then categorized as follows: Classification BMI Range Underweight Less than 18.5 Normal 18.5 or more, but less than 25.0 Overweight 25.0 or more, but less than 30.0 Obese 30.0...
