HeartRates.h
(class specification file)
HeartRates.cpp
(class implementation file)
application.cpp
(application program)
Your solution should use all three files listed above.
=====================================================
For your fourth programming assignment you will be writing the following C++ program:
The formula for calculating your maximum heart rate in beats per minute is 220 minus your age in years. Your target heart rate is a range that is 50–85% of your maximum heart rate. Create a class called HeartRates. The class attributes should include the person’s first name, last name and date of birth (consisting of separate attributes for the month of birth, day of birth, and year of birth). Your class should have a constructor that receives this data as parameters. For each attribute provide set and get functions.
The class also should include a function getAge that calculates and returns the person’s age (in years), a function getMaxiumumHeartRate that calculates and returns the person’s maximum heart rate and a function getTargetHeartRate that calculates and returns the person’s target heart rate. Function getAgeshould prompt the user to enter the current month, day and year before calculating the person’s age. Write an application program that prompts for the person’s information, creates an object of classHeartRatesand prints the information from that object—including the person’s first name, last name and date of birth—then calculates and prints the person’s age in (years), maximum heart rate and target-heart-rate range.
Sample run 2: Please enter first and last name (separated by spaces): Han Solo Please enter month, day, and year of birth (separated by spaces): 4 1 1980 First Name: Han Last Name: Solo Date of Birth: 4/1/1980 Please enter today's month, day, and year: 9 6 2017 Age: 37 Maximum Heart Rate: 183 Target Heart Rate: 91-155 Sample run 3: Please enter first and last name (separated by spaces): James Bond Please enter month, day, and year of birth (separated by spaces): 7 7 1977 First Name: James Last Name: Bond Date of Birth: 7/7/1977 Please enter today's month, day, and year: 9 6 2017 Age: 39 Maximum Heart Rate: 181 Target Heart Rate: 90-153Explanation / Answer
Here are the three code files of the given problem. In case of any query do write me in the comments:
HeartRates.h

string formatDOB(string inDOB);
int getAge();
string getFirstName();
string getLastName();
string getDateofBirth();
int getMaximumHeartRate(int age);
string getTargetHeartRate(int maxHrtRate);
};
