C++ Overloaded Hospital

Overloaded Hospital

Write a program that computes and displays the charges for a patient’s hospital stay. First, the program should ask if the patient was admitted as an in-patient or an out-patient. If the patient was an in-patient the following data should be entered:

·         The number of days spent in the hospital

·         The daily rate

·         Charges for hospital services (lab test, etc.)

·         Hospital medication charges

If the patient was an out-patient the following data should be entered:

·         Charges for hospital services (lab tests, etc.)

·         Hospital medication charges

The program should use two overloaded functions to calculate the total charges. One of the functions should accept arguments for the in-patient data, while the other functions accepts arguments for out-patient data. Both functions should return the total charges.

Input validation: Do not accept negative numbers for any information.
