需求分析

隨著經濟的發展和社會的進步，人民對物質生活與精神生活的要求也逐日高漲。對生產、生活條件越來越要求方便、舒適、高效、安全以及環保節能?_?倉庫管理系統應廣大人民的強烈需求應運而生。實現了基本的智能管理存儲商品名稱和庫存量的功能O_O

文件結構

開發環境

Windows 10 + Visual Studio 2017 Cummunity

功能

用戶注冊、登錄、修改密碼、獨立倉庫

商品進貨、出貨、展示、查詢、清空

文件存取

異常處理

限制數量輸入為9位正整數, 攔截字母或小數的輸入

商品名稱只取前100位避免越界

商品數量限度999999999, 避免進貨時超過

菜單選擇異常處理, 避免字母或小數或多位數的錯誤輸入

檢查只有回車的空密碼
