## Overview

This is a single-file, menu-driven dispensary inventory program. The user selects an operation; the main loop displays the menu and dispatches to medicine add, display, search, sale, deletion, or low-stock alert logic. Those operations read or modify a shared in-memory stock array and interact directly with the console. The README documents these capabilities and the 100-record, non-persistent limit; the supplied source confirms their implementation.

Main entry points: [`dispensary.c`](https://github.com/irfankazitech/hospital-management-system-c/blob/main/dispensary.c) (Menu loop)
