    • Secure login functionality
    • User session management
    • Access control

  • Complete CRUD Operations

    • Create: Add new items to inventory
    • Read: View all items and details
    • Update: Modify existing item information
    • Delete: Remove items from system

  • Transaction Management

    • Process item transactions
    • Track incoming/outgoing items
    • Transaction history

  • Data Persistence

    • File-based storage
    • Save and load data between sessions
    • Data integrity maintenance

🛠️ Technologies Used

  • C++: Core programming language
  • Standard Library: STL containers and file I/O
  • File Handling: Data persistence
  • OOP Principles: Classes and objects

🚀 Getting Started

Prerequisites

  • C++ compiler (GCC, Clang, or MSVC)
  • C++11 or higher standard support
  • Command line interface

Compilation

Using GCC:

g++ -o item_management hasil_akhir.cpp -std=c++11

Using Clang:

clang++ -o item_management hasil_akhir.cpp -std=c++11

Using Visual Studio:

  1. Open project in Visual Studio
  2. Build → Build Solution
  3. Run executable from Debug/Release folder

Running the Application

Linux/macOS:

./item_management

Windows:

item_management.exe

Or double-click the executable file.

💻 Usage Guide

Login

  1. Launch the application
  2. Enter credentials:
    • Username
    • Password
  3. Access main menu after successful authentication

Main Menu Options

  1. View Items - Display all inventory items
  2. Add Item - Create new item entry
  3. Update Item - Modify existing item
  4. Delete Item - Remove item from inventory
  5. Process Transaction - Handle item transactions
  6. Exit - Save and close application

Managing Items

Adding New Item

  1. Select "Add Item" from menu
  2. Enter item details:
    • Item code/ID
    • Item name
    • Category
    • Quantity
    • Price
    • Description
  3. Confirm to save

Viewing Items

  1. Select "View Items"
  2. See formatted list of all items
  3. Option to view detailed information

Updating Item

  1. Select "Update Item"
  2. Enter item code to update
  3. Modify desired fields
  4. Confirm changes

Deleting Item

  1. Select "Delete Item"
  2. Enter item code
  3. Confirm deletion
  4. Item removed from system

Processing Transactions

  1. Select "Process Transaction"
  2. Choose transaction type:
    • Stock In (adding items)
    • Stock Out (removing items)
  3. Enter item code and quantity
  4. Transaction logged and inventory updated

🗂️ Data Structure

Item Class

class Item {
private:
    string code;
    string name;
    string category;
    int quantity;
    double price;
    string description;
    
public:
    // Constructor
    Item(string c, string n, string cat, int qty, double p, string desc);
    
    // Getters and Setters
    string getCode();
    void setQuantity(int qty);
    // ... other methods
};

Transaction Record

struct Transaction {
    string itemCode;
    string type; // "IN" or "OUT"
    int quantity;
    string date;
    string time;
};

📊 File Storage

Data is stored in text files:

  • items.txt - Item inventory data
  • transactions.txt - Transaction history
  • users.txt - User credentials (if applicable)

File format example:

001|Item Name|Category|100|25.50|Description
002|Another Item|Category B|50|15.75|Description

🎓 Learning Objectives

This project demonstrates:
