Make a class to perform following tasks:

You are working on a program that will manage a list of appointments for a doctor's office. Each appointment should contain the following information: patient name, appointment date, and reason for appointment.

Make a C++ program that uses an STL queue to manage the list of appointments. Your program should allow the user to

• A function to add new appointments to the list,
• A function to remove appointments from the list, and
• A function to view a list of all appointments scheduled for the day.
• A function to sort the appointments by date or by patient name.

2.

Modify the program by assigning each of the task to a thread. Get the sorted appointment list back in main function and display in the main function.
