Answer:
#include <iostream>
# include <conio.h>
using namespace std;
float fat_burning_heart_rate(float age);
main()
{
float age,bpm;
cout<<"enter the age of the person"<<endl;
cin>>age;
if (age>=18 && age<=75)
{
bpm=fat_burning_heart_rate(age);
cout<<"fat burning heart rate for the age of"<<age<<"="<<bpm;
}
else
cout<<"Invalid age";
getch();
}
float fat_burning_heart_rate(float age)
{
float a;
a= (220-age)*0.7;
return a;
}
Step-by-step explanation:
In this program, the variable named as age has been taken to enter the age of the person, needs to calculate the burning heart rate. All the variables taken in float, as the age and fat burning heart rate should come in decimal value.
The formula has been used as mention in question that,
a= (220-age)*0.7;
