⚙️ How It Works

The system allows users to manage inventory through a menu:

1. Add Product
2. View Products
3. Search Product
4. Update Quantity
5. Delete Product
6. Total Inventory Value
7. Show Low Stock Products
8. Exit

If a product's quantity goes below the minimum stock level, the system shows:

⚠ LOW STOCK ALERT
