Assigment #2 Q#8

 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. Computerizing health records could make it  easier for patients to share their  health  profiles  and  histories  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. Design a “starter” HealthProfile structure for a person. The structure’s members 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 program should have a function  that receives  this data and uses it to set the members of a HealthProfile variable. The program also should  include functions that calculate and return the user’s age in years, maximum heart rate and targetheart-rate range

The program  should prompt for the person’s information, create a HealthProfile variable for that person  and  display  the  information  from  that  variable—including  the  person’s  first  name,  last name, gender,  date of birth, height and weight—then it should calculate and display the person’s
age  in  years,  BMI,  maximum  heart  rate  and  target-heart-rate  range.  It  should  also  display  the “BMI values” chart.
Hints:

-  According  to  the  American  Heart  Association  (AHA)
(www.americanheart.org/presenter.jhtml?identifier=4736),  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. [Note: These formulas are estimates provided by the AHA. Maximum and target heart rates may vary based on the health, fitness and gender of the individual. Always consult a physician or qualified health care professional  before beginning or modifying an exercise program.],  and body mass index).
  The formulas for calculating BMI are:
BMI =   Weight In Kg’s/(Height In Meters)^2

or

BMI = (Weight in pounds  x 703)/( Height in Inches)^2
