/* Using Files - Hospital Report - This program is a modification of
Programming Challenge 6.15. In this version the final report is
written to a file.
********************************************************************
Overloaded Hospital - This program computes and displays the charges
for a patient's hospital stay. First the program asks 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
* Hospital medication charges
* Charges for hospital services (lab tests, etc.)
If the patient was an out-patient, the following data should be
entered:
* Charges for hospital services (lab tests, etc.)
* Hospital medication charges
This program uses two overloaded functions:
* getPatientData()
* getPatientData()
Input Validation: This program does not accept negative numbers for
any data.
