## Overview

A small C command-line product-inventory manager. The user selects operations in a menu to add, display, delete, load, search, edit, and sort products; the program stores products in a linked list and reads or writes product data to files. The source also contains inventory statistics and edit-history saving. The README gives no further product detail, and the source excerpt omits some menu and helper code, so uncertain call wiring is left out.

Main entry points: [`d/qlsieuthilinked.c`](https://github.com/itsdoritos/tieuluandsa/blob/main/d/qlsieuthilinked.c) (Menu loop), [`d/products.txt`](https://github.com/itsdoritos/tieuluandsa/blob/main/d/products.txt) (Product data)
