## Overview

This is a terminal-based hospital patient and bed management program. A user enters through password setup, reaches the main menu, and can register, edit, display, or delete patient records, inspect the patient list and count, or check bed availability. Patient IDs correspond to slots in a fixed-capacity, in-memory patient store; bed availability is tracked alongside those records. The excerpts show menu dispatch and direct state access, but not persistent storage. README-listed capabilities are represented where supported; the sampled code is incomplete.

Main entry points: [`HospitalManagementSystem.c`](https://github.com/dantondanvin/hospital-management-system/blob/main/HospitalManagementSystem.c) (Patient menu)
