Write a program that calculates an adult's fat-burning heart rate, which is 70% of 220 minus the person's age. Complete fat_burning_heart_rate() to calculate the fat burning heart rate. The adult's age must be between the ages of 18 and 75 inclusive. If the age entered is not in this range, raise a ValueError exception in get_age() with the message "Invalid age." Handle the exception in __main__ and print the ValueError message along with "Could not calculate heart rate info." Ex: If the input is: 35 the output is: Fat burning heart rate for a 35 year-old: 129.5 bpm If the input is: 17 the output is: Invalid age. Could not calculate heart rate info.

#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;

}

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;

answerthe above statement is (true);
