Travel Expenses

Create an application that calculates and displays the total travel expenses for a business trip. The user must provide the following information:

•Number of days on the trip
•Amount of airfare, if any
•Amount paid for meals, if any
•Amount of car rental fees, if any
•Number of miles driven, if a private vehicle was used
•Amount of parking fees, if any
•Amount of taxi charges, if any
•Conference or seminar registration fees, if any
•Lodging charges, per night

The company reimburses travel expenses according to the following policy:

•$37 per day for meals
•Parking fees, up to $10.00 per day
•Taxi charges up to $20.00 per day
•Lodging charges up to $95.00 per day
•If a private vehicle is used, $0.27 per mile driven

The application should calculate and display the following:

•Total expenses incurred by the business person
•The total allowable expenses for the trip
•The excess that must be paid by the business person, if any
•The amount saved by the business person if the expenses were under the total allowed

The application should have the following functions:

CalcMeals	Calculates and returns the amount reimbursed for meals.
CalcMileage	Calculates and returns the amount reimbursed for mileage driven in a private vehicle.
CalcParkingFees	Calculates and returns the amount reimbursed for parking fees.
CalcTaxiFees	Calculates and returns the amount reimbursed for taxi charges.
CalcLodging	Calculates and returns the amount reimbursed for lodging.
CalcTotalReimbursement	Calculates and returns the total amount reimbursed.
CalcUnallowed	Calculates and returns the total amount of expenses that are not allowable, if any. These are parking fees that exceed $10.00 per day, taxi charges that exceed $20.00 per day, and lodging charges that exceed $95.00 per day.
CalcSaved	Calculates and returns the total amount of expenses under the allowable amount, if any. For example, the allowable amount for lodging is $95.00 per day. If a business person stayed in a hotel for $85.00 per day for five days, the savings would be $50.00.

Input validation: Do not accept negative numbers for any dollar amount or for miles driven in a private vehicle. Do not accept numbers less than 1 for the number of days
