Write a program using functions, arrays, and structures to calculate and display

Question

Write a program using functions, arrays, and structures to calculate and display the total expenses for a business person on a trip. The following is input from the user: total number of days spent on the trip; time of departure on the first day of the trip; time of arrival back home on the last day of the trip; amount of round-trip airfare(if any); amount of car rental fees per day (if any); miles driven if a private vehicle was used per day; parking fees per day (if any); Taxi/Uber fees per day (if any); conference or seminar registration fees; hotel expenses per night; and the amount of each meal eaten, per day.
Additional Information:
•Total days on trip cannot be less than 1 or greater than 10. •Vehicle expense for personal vehicle use if 54.5 cents/mile. •Taxi/Uber fees: $20 max per day will be covered. •Parking fees: $6.00 max per day will be covered. •Hotel expenses: $110.00 max per night will be covered. •Meal expenses:
-On the first day of the trip •Breakfast is allowed if the departure time is before 7:00 am. •Lunch is allowed if the departure time is before 12:00 pm. •Dinner is allowed if the departure time is before 6:00 pm.
-On the last day of the trip: •Breakfast is allowed if the arrival time is after 7:00 am. •Lunch is allowed if the arrival time is before 1:00 pm. •Dinner is allowed if the arrival time is after 7:00 pm.
•Your program should only ask for ALLOWABLE meals. •Max covered prices are (per day that the business person is on a trip and is allowed these meals ) -Breakfast : $12.00 -Lunch: $15.00 -Dinner: $19.00
Your program should calculate and display the total expenses for each category; the total amount of expenses incurred; the total amount covered by the company, the total amount the employee will not be reimbursed for (if any) for anything spent over the max covered amounts.

This is what I’ve got so far. I need help with the logic and programming of this assignment please and thank you.

Explanation / Answer

The above program is not correct as per my data. The program runs in infinite loop.

To calculate the total expenses with the information given follow the below program code , this might help you:

  #include <iostream>  #include <iomanip>    using namespace std;    int getDays(int);  void getTime (double&, double&);  double getAirfareAmount(double);  double getCarRentalAmount (double);  double getPrivateVechileExpense(double);
