Dealing with Data (C++ Primer Plus Sixth Edition Solution Manual) Question-2

Leave a Comment
Questions:

Write a short program that asks for your height in feet and inches and your weight in pounds. (Use three variables to store the information.) Have the program report your body mass index (BMI). To calculate the BMI, first convert your height in feet and inches to your height in inches (1 foot = 12 inches).Then convert your height in inches to your height in meters by multiplying by 0.0254.Then convert your weight in pounds into your mass in kilograms by dividing by 2.2. Finally, compute
your BMI by dividing your mass in kilograms by the square of your height in meters. Use symbolic constants to represent the various conversion factors.

Explanation:

Below mention code is compiled in Visual Studio 2015 and Code Blocks 13.12,output snap is attached.. If any problem you feel and you want some explanation feel free to contact us.

Code:

#include <iostream>
#include <cmath>
using namespace std;
void main() {
       cout << "Enter your height in feet and inches:" << endl;
       cout << "First, enter the feet:";
       int feet;
       cin >> feet;
       cout << "Second, enter the inches:";
       int inch;
       cin >> inch;
       cout << "Enter your weight in pounds:";
       int pounds;
       cin >> pounds;
       const int inchesPerFoot = 12;
       int inches = feet * inchesPerFoot + inch;
       const float meterPerInch = 0.0254;
       float meters = inches * meterPerInch;
       const float poundsPerKg = 2.2;
       float weight = pounds / poundsPerKg;
       float bmi = weight / sqrt(meters);
       cout << endl<< "Your Body Mass Index (BMI) is: "<< bmi<< endl;
}
