📇 Contact Management System (C++)

A console-based Contact Management System built with C++ that allows users to store, search, update, and delete contact information. All contacts are saved in a file so the data persists even after the program is closed.

Description

The Contact Management System is a simple yet practical C++ application designed to help users manage personal or professional contacts efficiently.

Each contact contains the following information:

• Name
• Phone Number
• Email Address
• Home Address

The program stores all contacts in a text file (contacts.txt), allowing users to retrieve their saved contacts whenever they run the program again.

This project demonstrates key programming concepts such as:

• Object-Oriented Programming (OOP)
• File Handling
• Dynamic Data Storage using Vectors
• String Searching
• Menu-Driven Applications

Features

Add new contacts View all saved contacts Search contacts by name or phone number Edit existing contacts Delete contacts Automatic file saving Persistent storage using a text file

Technologies Used

• C++
• Standard Template Library (STL)
• Vectors
• File Handling (ifstream, ofstream)
• Object-Oriented Programming
