C++ code: digital rolodex using a doubly linked list

  
You will be making a digital rolodex using a doubly linked list. Your program will have the following criteria:
1. Each node in the list will contain the following information about the person:
     First Name
     Last Name
     Address
     Phone Number
     Email Address
     twitter handle.
2. When the program opens it will read contact information from a text file and create a doubly linked list with the information.
3. The user will be able to:
    o search for and display specific user by any piece of information. Exact matches only is fine. Should be able to navigate through a list if there are multiple results. thus, you probably want to sort first.
    o add a contact to the rolodex
    o delete a user from the rolodex
    o sort the rolodex by any piece of information and navigate through it, displaying    one contact at a time. (they will need to be able to exit this navigation mode)
    o quit the program.
4. Upon quitting, all contact information should be written back to the text file.
