Answer to Question #284352 in C++ for jye

Question

Build a patient base class consisting of

Attributes: full name (string), hometown (string), year of birth (int)

Functions: Create, import, and export information

Build a medical record class that inherits public from the patient class, adding:

Attributes: medical record name (string), hospital charge amount (double)

Functions: Create, import, export information, calculate current age.

Write a main program that does:

Enter a list of N medical records

Sort the list by descending age of the patients

Display the list of patients with age <=10

Show information of the patients with the highest hospital fees
