## Overview

CarServiceCenter is a console car-service simulation. Its Center orchestrates cars through arrival scheduling, diagnosis, service waiting and bays, then completion or cancellation; the UI displays timestep state. The excerpts establish the UI’s read-only reporting and several list implementations, while Center.h documents the simulator stages and ownership. Center.cpp was read but not excerpted, so its internal transition calls are not asserted here; unsampled stage links are limited to documented Center responsibilities.

Main entry points: [`CarServiceCenter/UI.h`](https://github.com/yaraahmedrashid-dev/carservicecenter/blob/master/CarServiceCenter/UI.h) (Console UI), [`CarServiceCenter/Center.cpp`](https://github.com/yaraahmedrashid-dev/carservicecenter/blob/master/CarServiceCenter/Center.cpp) (Center Engine), [`CarServiceCenter/ServiceSeqList.h`](https://github.com/yaraahmedrashid-dev/carservicecenter/blob/master/CarServiceCenter/ServiceSeqList.h) (Service Sequence), [`CarServiceCenter/ServiceWaitList.h`](https://github.com/yaraahmedrashid-dev/carservicecenter/blob/master/CarServiceCenter/ServiceWaitList.h) (Service Wait Lists)
