2.24 LAB: Expression for calories burned during workout

2.24 LAB: Expression for calories burned during workout

The following equations estimate the calories burned when exercising (source):

Women: Calories = ( (Age x 0.074) — (Weight x 0.05741) + (Heart Rate x 0.4472) — 20.4022 ) x Time / 4.184

Men: Calories = ( (Age x 0.2017) + (Weight x 0.09036) + (Heart Rate x 0.6309) — 55.0969 ) x Time / 4.184

Write a program with inputs age (years), weight (pounds), heart rate (beats per minute), and time (minutes), respectively. Output calories burned for women and men.

Output each floating-point value with two digits after the decimal point, which can be achieved by executing
cout << fixed << setprecision(2); once before all other cout statements.

Ex: If the input is:

49 155 148 60

the output is:

Women: 580.94 calories
Men: 891.47 calories

The lab is on zybooks and it is coded in c++ please help I'm stuck.

Answer 1

Program:

   #include <iostream>
   #include<stdio.h>
   #include<iomanip>
   using namespace std;

   int main()
   {
      
       //variables to store the input
       int Age,Weight,Heart_Rate,Time;
      
       //gets the inputs from the user
       //cout<<"Enter Age, Weight, Heart_Rate and Time separated by a space:"<<endl;
       cin>>Age>>Weight>> Heart_Rate>>Time;
       cout<<endl;
      
      
       //computes and displays calories for women
       cout << fixed << setprecision(2);
       cout<<"Women: "<<((Age*0.074)-(Weight * 0.05741)+(Heart_Rate*0.4472)-20.4022)*Time/4.184<<" Calories "<<endl;
      
      
       //computes and displays calories for men
       cout<<"Men: " <<((Age*0.2017)+(Weight*0.09036)+(Heart_Rate*0.6309)-55.0969)*Time/4.184 <<" Calories "<<endl;
      
       return 0;
   }

Output:
