Answer to Question #114860 in C++ for redomoditswe

Question

BMI or Body Mass Index is a method of estimating a person's body fat levels based on a person's weight and height measurement. The BMI is calculated by dividing the person’s body mass/weight (in kilograms) by the square of the body height (in metres). The result is universally expressed in units of kg/m2. BMI formula: BMI = weight /(height)2 BMI Weight status Below 18.5 Underweight 18.5‐24.9 Healthy 25.0‐29.9 Overweight 30.0 and above Obese

Write a program that calculates a person’s BMI and displays the weight status according to the BMI value, indicating whether the person is underweight, healthy, overweight or obese. The BMI weight statuses and related values are listed in the above table.

The program should have the following functions: 1.1. getData that prompts and returns their weight and height; (5) 1.2. calcBMI to calculate the BMI ; (5) 1.3. displayFitnessResults to display the BMI and relevant weight status message; (5) 1.4. ma

Answer 1

#include <iostream>
#include <vector>


using namespace std;


//getData function
vector<double> getData() {
	double a, b;
	cout << "Enter your mass(kg): ";
	cin >> a;
	cout << "Enter your height(m): ";
	cin >> b;
	vector<double> c;
	c.push_back(a);
	c.push_back(b);
	return c;
}
//calcBMI function
double calcBMI(vector<double> c){
	double t = c[0] / (c[1] * c[1]);
	return t;
}
//displayFitnessResults function
void displayFitnessResults(double t) {
	if (t < 18.5)
		cout << "Underweight";
	if (t >= 18.5 && t < 25)
		cout << "Healthy";
	if (t >= 25 && t < 30)
		cout << "Overweight";
	if (t >= 30)
		cout << "Obese";
}


int main() {
	vector<double> c;
	double t;
	c=getData();
	t = calcBMI(c);
	displayFitnessResults(t);
	return 0;
