C++ Inventory Management System

This was a group project completed with a fellow student as part of coursework. I was primarily responsible for the overall implementation, including planning, coding, and testing.

Project Overview

This Inventory Management System is a console-based application written in C++ with persistant SQLite storage and modern_sqlite_cpp library file.
It allows users to manage product records including:

• Searching by product name - to view all its details
• Adding new items
• Removing entries
• Updating product details
• Viewing the complete inventory

Each product consists of:

• Name
• Price
• Quantity

---

1. Start
2. Load the default inventory from the database
3. Display menu options:
   - If no items exist, show only the "Add" option
4. Take user input for the desired action
5. Execute chosen action via DAO/CLI:
   - Search, Add, Remove, Update, View, or Exit
6. Repeat steps 3–5 until the user chooses to exit (default option `0`)

How to Compile and Run

Tools Used

• g++ - C++ Compiler
• SQLite (for persistant Storage)
• VSCode - IDE

The following things are also installed (for Ubuntu)

sudo apt install libsqlite3-dev sqlite3

But its too verbose, hence an easy solution, i found was sqlite_modern_cpp, its syntax is quite easy and clear.

sudo apt install libspdlog-dev

git clone [https://github.com/ch-arslanahmad/inventory-management-cpp/](https://github.com/ch-arslanahmad/inventory-management-cpp/)
cd inventory-management-cpp
g++ main.cpp -o main -lsqlite3  

To run the executable: Code snippet

main.exe # if on Windows
./main # if on Linux/macOS

Applications

This system has both real-world and educational use cases:

• Managing stock for small businesses or home-based shops
• Teaching fundamental C++ programming concepts
• Prototyping a point-of-sale or inventory software
• Organizing personal collections (e.g., books, tools)

Notes

This project was developed for the Programming Fundamentals course in Semester 2. It demonstrates foundational concepts in C++ such as:

• Loops and conditionals
• Functions and user-defined structures
• Vector manipulation
• Console I/O handling

Updates (Self)

• Refactor Code & Added persistent SQLite storage via sqlite_modern_cpp
• Implemented menu-based CRUD operations of the database
