## Overview

This is a console mini-shop manager. A user chooses the admin or shopper menu, then performs catalogue operations; shopper purchases and product searches update the in-memory catalogue. Shared functions also provide category browsing and price/count queries. The sampled source supports these direct calls and shared-state accesses; the README gives no further product detail.
