(Computerization of Health Records) A health care issue that has been in the news lately is the computerization of health records. This possibility is being approached cautiously because of sensitive privacy and security concerns, among others. [We address such concerns in later exercises.] Computerizing health records could make it easier for patients to share their health profiles and his-
tories among their various health care professionals. This could improve the quality of health care, help avoid drug conflicts and erroneous drug prescriptions, reduce costs and in emergencies, could save lives. In this exercise, you’ll design a “starter” HealthProfile class for a person. The class attri- butes should include the person’s first name, last name, gender, date of birth (consisting of separate attributes for the month, day and year of birth), height (in inches) and weight (in pounds). Your class should have a constructor that receives this data. For each attribute, provide set and get functions. The class also should include functions that calculate and return the user’s age in years, maximum heart rate and target-heart-rate range (see Exercise 9.25), and body mass index (BMI; see Exercise 2.30). Write an application that prompts for the person’s information, instantiates an object of class HealthProfile for that person and prints the information from that object—including the person’s first name, last name, gender, date of birth, height and weight—then calculates and prints the per- son’s age in years, BMI, maximum heart rate and target-heart-rate range. It should also display the “BMI values” chart from Exercise 2.30. Use the same technique as Exercise 9.25 to calculate the per- son’s age. What will be an ideal response?
