In order for excercise to be beneficial to the cardiovascular system, the heart

Question

In order for excercise to be beneficial to the cardiovascular system, the heart rate (number of hear beats per minute) must exceed a value called the training hear reate, THR. A person's THR can be calculated from his or her age and resting heart rate (pulse rate when first awakening) as follows :

(a) calculate the maximum hear rate as 220-age.

(b) subtract the resting heart rate from the maximum heart rate

(c) multiply the result in step (b) by 60% and then add the resting heart rate.

write a program to request a person's age and resting heart rate as input and display his or her THR.

Explanation / Answer

Please find the program written in C++ as per the requirement:

#include <iostream>
using namespace std;

int main() {
   int age,restingHR, maxHR;
   float THR;
  
   cout<<"Please enter Age and Resting Heart Rate";
   cin>>age>>restingHR;
   cout<<endl;
  
   while ((age <= 0) or (restingHR <= 0)){
cout << "Invalid Values. Please enter valid values greater than zeros: "<<endl;
cin>>age>>restingHR;
   }
  
maxHR = 220 - age;
THR = (maxHR - restingHR)*0.6 + restingHR;
  
cout<<"Training Heart Rate THR is: "<<THR<<endl;
  
   return 0;
}

Testing:

Input:

40 77

Output:

Training Heart Rate THR is: 138.8
