Question

Write a program that calculates and displays a person's body mass index (BMI). The BMI is often used to determine whether a person with a sedentary lifestyle is overweight or underweight for his or her height. A person's BMI is calculated with the following formula: BMI = weight times 703/height^2 where weight is measured in pounds and height is measured in inches. The program should display a message indicating whether the person has optimal weight, is underweight, or is overweight. A sedentary person's weight is considered to be optimal if his or her BMI is between 18.5 and 25. If the BMI is less than 18.5, the person is considered to be underweight. If the BMI value is greater than 25, the person is considered to be overweight. Input Validation: Determine what inputs the program needs the user to enter and what legal values the program should accept for these inputs.

Explanation / Answer

#include <iostream>

using namespace std;

int main()

{

int weight;

float height,BMI;

cout<<"Please enter your weight in pounds:";

cin>> weight;

cout<<" Please enter your height in inches:";

cin>>height;

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

cout<<" Your body mass index is: "<<BMI;

if(BMI > 25)

cout<<" you are some what overweight";

else if(BMI<18.5)

cout<<" you are somewhat underweight.";

else if (BMI > 18.5 && BMI < 25)

cout<<" Congratulations you are within a healthy weight range.";

cin.get();

cin.get();

return 0;

}
