Create a phonebook using c++

In this program, we are going to create a Phone Book, which will allow users to add, remove, modify, and list contacts for the book using a basic command console menu. The data for each contact will be stored and managed as a node inside an ordered doubly linked list.

The program should support the following commands:
1. Add New Contact
2. Edit Contact
3. Remove Contact
4. List Contact
5. Exit Program
