Phase $1$: Contact Management Svstem

Introduction:

The Contact Management System is a console$-$based application developed in C$++.$ The

system aims to manage contacts using structures to store information about each

contact, including a unique ID$,$ name, phone number, email, and address. The project

utilizes functions to perform essential operations like adding contacts, sorting them by

name, searching for a contact by name, and displaying contacts based on various

criteria.

Structures Used:

Address Structure:

street $[$string$]$

city $[$string$]$

state $[$string$]$

postalCode $[$string$]$

Contact Structure:

id $[$int$]$

name $[$string$]$

phoneNumber $[$string$]$

email $[$string$]$

address $[$Address structure$]$

Your system must have at least these functions

readContactsFromFile: Reads contact information from a file named "contacts.txt$"$ into the system.

writeContactsToFile: Writes all contact information from the system into a file named "contacts.txt$".$

displayContact: Displays detailed information about a specific contact.

displayAlicontacts: Displays information for all stored contacts.
