Using linked lists, design an online contacts list to keep track of the names (first and last), phone numbers, email addresses, and dates of birth of family members, close friends, and certain business associates.

Your program must complete the following operations: ' Read the raw data into the contacts list from an input file named "data.txt"( ' Add a new entry to the contacts list (i.e., add to the end of the list) . Delete an entry from the contacts list, based on the user's choice " Print the final contacts list (formatted as a table) to an output file named "your_last_name>Contacts.txt
