Question

The following equations estimate the calories burned when exercising (source):Men: Calories = ( (Age x 0.2017) — (Weight x 0.09036) + (Heart Rate x 0.6309) — 55.0969 ) x Time / 4.184Women: Calories = ( (Age x 0.074) — (Weight x 0.05741) + (Heart Rate x 0.4472) — 20.4022 ) x Time / 4.184Write a program using inputs age (years), weight (pounds), heart rate (beats per minute), and time (minutes), respectively. Output calories burned for men and women.Output each floating-point value with two digits after the decimal point, which can be achieved as follows:printf("%0.2lf", yourValue);Ex: If the input is:

Answer 1

// program in C.

#include <stdio.h>

// function to calculate calories burned

double calories_burned(int age,double weight,double heart_rate,int i_time, char gen)

{

// variable

double calories=0;

if(gen=='m')

// calories burned by men

calories = ((age * 0.2017 )- (weight * 0.09036) + (heart_rate * 0.6309) - 55.0969) * (i_time / 4.184);

else if(gen=='f')

// calories burned by Women

calories = ((age * 0.074) - (weight * 0.05741) + (heart_rate * 0.4472) - 20.4022) * (i_time / 4.184);

// return calories burned

return calories;

}

// main function

int main()

{

// variables

int u_age;

double u_weight,heart_rate;

int i_time;

printf("Enter age (years):");

// read age

scanf("%d",&u_age);

printf("Enter weight (pounds):");

// read weight

scanf("%lf",&u_weight);

printf("Enter heart rate (beats per minute):");

// read heart_rate

scanf("%lf",&heart_rate);

printf("Enter time (minutes):");

// read time

scanf("%d",&i_time);

// call function for men

double men_cal=calories_burned(u_age,u_weight,heart_rate,i_time,'m');

// call function for women

double women_cal=calories_burned(u_age,u_weight,heart_rate,i_time,'f');

// print calories burned by men

printf("Men calories burned :%0.2lf \\", men_cal);

// print calories burned by Women

printf("Women calories burned :%0.2lf \\", women_cal);

return 0;

}

Step-by-step explanation:

Read age, weight, heart rate and time from user.Then call the function calories_burned() with all the input and a character parameter for men.This function will calculate the total calories burned by the men.Similarly call the function again for women, Then it will return the calories burned by women.Print the calories burned by men and women.

Output:

Enter age (years):20

Enter weight (pounds):175

Enter heart rate (beats per minute):144

Enter time (minutes):60

Men calories burned :343.79

Women calories burned :508.05
