Question

** Create a constructor that initializes ONLY the name and date-of-birth data-fields(i.e. takes two arguments). Also, increment the patient counter static variable.

** Create a constructor that initializes ALL data-fields. Also, increment the patient counter static variable.

** Create getters/setters for ALL the above data-fields. Should be 14 in total.

** Create a getter method for the static variables that keeps tracks of how many patient objects are created.
