2. Hospital Charges 

Create an application that calculates the total cost of a hospital stay. The application should accept the following input:


• The number of days spent in the hospital, as an integer

• The amount of medication charges

• The amount of surgical charges

• The amount of lab fees

• The amount of physical rehabilitation charges


The hospital charges $350 per day. The application’s form should resemble the one shown in Figure 6-23.


Create the following functions:


* CalcStayCharges Calculates and returns the base charges for the hospital stay. This is computed as $350 times the number of days in the hospital.

* CalcMiscCharges Calculates and returns the total of the medication, surgical, lab, and physical rehabilitation charges.

* CalcTotalCharges Calculates and returns the total charges.

* ValidateInputFields Checks the validity of the input fields by converting each to a numeric value and checking its range. If any input field is found to be invalid, this function displays an error message and returns a value of False.


Input Validation: Do not accept a negative value for length of stay, medication charges, surgical charges, lab fees, or physical rehabilitation charges. When displaying error messages, use a Label control and specifically name the missing field and the type of data to be entered (integer or numeric).
