## Overview

This is a small, menu-driven bus stand management program. The user can add buses, list them, inspect seat availability, book seats, and view bus status. All operations run in one process and share fixed-size global arrays; there is no persistent storage or separate service layer. The README identifies the project but documents no additional capabilities, so this map follows the behavior visible in main.cpp.

Main entry points: [`main.cpp`](https://github.com/shahmeerabdul/busilo/blob/main/main.cpp) (Menu loop)
