Problem Travel Expenses using functions:

Write a program that calculates and displays the total travel expenses of a businessperson on a trip. The program should declare all variables in the main function and then call the functions to ask for and return the following:

The total number of days spent on the trip

The time of departure on the first day of the trip, and the time of arrival back home on the last day of the trip

The amount of any round-trip airfare

The amount of any car rentals

Miles drive, if a private vehicle was used. Calculate the vehicle expense as $0.50 per km driven.

Parking fees (The company allows up to $10 per day. Anything in excess of this must be paid by the employee.)

Taxi fees, if a taxi was used anytime during the trip (The company allows up to $20 per day, for each day a taxi was used. Anything in excess of this must be paid by the employee.)

Conference or seminar registration fees

Hotel expenses (The company allows up to $90 per night for lodging. Anything in excess of this must be paid by the employee.)

The amount of each meal eaten. On the first day of the trip, breakfast is allowed as an expense if the time of departure is before 7am. Lunch is allowed if the time of departure is before 12 noon. Dinner is allowed on the first day if the time of departure is before 6pm. On the last day of the trip, breakfast is allowed if the time of arrival is after 8am. Lunch is allowed if the time of arrival is after 1pm. Dinner is allowed on the last day if the time of arrival is after 7pm. The program should only ask for the amounts of allowable meals. (The company allows up to $9 for breakfast, $12 for lunch, and $16 for dinner. Anything in excess of this must be paid by the employee.)

The program should calculate and display the total expenses incurred by the businessperson, the total allowable expenses for the trip, the excess that must be reimbursed by the businessperson, if any, and the amount saved by the businessperson if the expenses were under the total allowed.

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. Only accept valid times for the time of departure and the time of arrival.

What to hand in:

Copy your source code into your Word document

Several runs to show your program works with valid and invalid data

A User Guide for the “businessperson”

A hierarchy chart to show the relationship of your functions.

Prototypes may look like the following:

// Function prototypes

int daysSpent();

void times(double &, double &);

bool isValidTime(double);

double airFare();

double carRental();

double vehicle();

double parking(int);

double taxi(int);

double registration();

double hotel(int);

double meals(int, double, double);

double getBreakfast();

double getLunch();

double getDinner();

// Global variable to hold total expenses of employee

double totalExpenses = 0;
