A hospital maintains the patient and the IPD details using two distinct classes. The Patient class has name, age and gender as its constituent attributes while the IPD class has wardNumber, bedNumber and chargePerDay as its attributes. BillingInfo is a special class that is used to compute the total charges a patient has to pay and also displays the patient details and IPD details of the corresponding patient. The BillingInfo class has noOfDaysAdmitted as an attribute and computes the total

bill as a product of chargePerDay and noOfDaysAdmitted. The hospital also provides 10% discount if a patients bill exceeds 1,00,000. Write a C++ program to accept the patient and IPD details of any number of users (take the no.of patients as an user input at beginning) and display the billing details.

NOTE: Use the concepts of inheritance.
