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

   -  Hospital medication charges

   - Charges for hospital services (lab tests, etc)

The program should ask for the following data if the patient was an out-patient:

    - 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 function accepts arguments for the out-patient information. Both functions should return the total charges.

Input Validation: Do not accept negative numbers for any data.
