## Overview

HMS is a terminal-based hospital operations program. A user selects a menu workflow to manage patients, beds, doctors, bills, appointments, emergency triage, or search and sorting; the program loads binary records at startup and saves changes and data on exit. The runtime is implemented in one C file, so distinct responsibilities share the same path. README capabilities are included, but omitted source excerpts limit certainty about some cross-feature calls.

Main entry points: [`HMS.c`](https://github.com/aaravsingh23/hospital-management-sysytem/blob/main/HMS.c) (Main and feature menus)
