## Overview

This is a terminal parking-facility vehicle registry. The user starts the program, chooses a menu action, and can register, list, remove, search, or update vehicle entry records. The single C file keeps records in a global in-memory array; registration validates entry time before storing it, while search and update operate on that array. The README documents all major operations, but excerpts omit several menu branches and implementations, so those relationships are shown as unverified rather than asserted as source-visible calls.

Main entry points: [`Vehicle_Management_System.c`](https://github.com/mahadihasanx/vehicle-management/blob/main/Vehicle_Management_System.c) (Main menu)
