OOP Lab 02: Patient Admission & Bill Comparison

Problem Objective

Implement a Patient class with private attributes: patientID (int), daysAdmitted (int), and dailyCharge (double).

Provide a constructor with default daily charge: Patient(int id, int days, double charge = 500.0).

Validate inputs: ensure daysAdmitted and dailyCharge cannot be negative (set to 0 or 500 if negative).

Implement calculateBill(int discount = 0) that returns (daysAdmitted * dailyCharge) - discount, ensuring the total never drops below 0.

Implement a standalone function Patient compareBills(Patient p1, Patient p2) that calculates the bill for both and returns the Patient object with the higher bill.

In main(), instantiate patients, compute bills with and without discounts, and find the highest bill using compareBills.

Expected Terminal OutputStandard Out

[Patient 1] Patient ID: 201 | Days: 4 | Rate/Day: $450.00 | Total Bill: $1800.00
[Patient 2] Patient ID: 202 | Days: 5 | Rate/Day: $500.00 | Total Bill: $2500.00
[Patient 3] Patient ID: 203 | Days: 3 | Rate/Day: $600.00 | Total Bill: $1800.00
Patient 2 with $300 discount: $2200.00
Higher Bill: Patient ID 202 with bill $2500.00

Execution Constraints

›Private member variables for patientID, daysAdmitted, dailyCharge
›Default argument dailyCharge = 500.0 and discount = 0
›compareBills must be a standalone function returning a Patient object
›Bill amount must be strictly non-negative
