## Overview

A Windows-oriented, menu-driven hospital administration program. The operator selects doctor or patient record operations, manages treatment details, checks billing or views statistics; records are held in memory and persisted to text files. The implementation is concentrated in main.c, so components below describe its runtime responsibilities rather than separate modules. The source excerpts are partial; README-documented capabilities are included, but uncertain internal call wiring is omitted.

Main entry points: [`main.c`](https://github.com/0xfaysal/hospital-management-system/blob/main/main.c) (Menu controller)
