  Project: PatientStructure (based on very similar example by Dr. Ross.)
  File: main.cpp (file v. 1.0)

  Simulates a patient database. See comments in patients.cpp regarding purpose 
  use of each function. This function just populates the database and initates 
  update of one record.
  
  This program is for demonstration only. Input is not validated and array 
  limits are not checked. This is bad programming practice, but okay for "toy"
  programs like this.
