🛒 Electronic Shop Management System

A console-based C++ application designed to help small electronics shops manage their inventory, billing, and daily operations efficiently. This system supports item management (add/update/delete), sales processing, and persistent storage using binary files—all wrapped in a password-protected interface.

⚙️ How It Works

📦 Item Structure

Each item stored includes:

• Item Code: A unique identifier
• Item Name: Name of the electronic product
• Price: Price per unit
• Quantity: Quantity available

These are stored in a binary file (itemstore.dat) for persistence.

💵 Billing Process

• User is prompted to input item name and quantity
• If available, total cost is calculated and shown
• Final bill with itemized breakdown is displayed

🗂 Code Structure

Section	Description
main()	Entry point with login & menu loop
class item	Contains item data and methods like add(), show(), search(), etc.
File operations	Binary file handling for saving and retrieving item data
Authentication	Basic user login system with validation
UI elements	Text-based menu system and status messages

---

🛠 Technologies Used

• Language: C++
• File I/O: Binary file handling (fstream)
• Data Handling: Classes and objects
• Interface: Console/Terminal

---

⚠️ Limitations

• Not cross-platform GUI — terminal only
• Passwords stored in plain text
• No input validation or error recovery for file corruption
• No database integration
