基于C++开发的仓库管理系统（附源码）_c++仓库管理系统源代码

 

一、简介

  仓库管理系统的功能有登录、注册、查询功能、入库功能、出库功能、添加商品、删除商品、退出，按下相应的数字键后进入各自的功能，用户的信息和商品的信息分别保存在user.txt和good.txt中，保存在文本文件中的数据不会轻易的遗失，可以很好的保存好用户和商品的信息。
 

1、开始菜单

  开始菜单为注册、登录、退出，注册时会将用户填写的信息写入user.txt中，注册时需要输入两次密码，保证用户密码的准确，注册成功后会在下方提示用户注册成功。登录时会提取user.txt中的用户数据进行登录验证，登录成功后会在下方提示用户登录成功。退出是退出当前的菜单。


 

2、登录后的菜单

  登录后的菜单为查询功能、入库功能、出库功能、添加商品、删除商品、退出。

 
  在查询功能中，可以查询当前用户的信息，也可以根据商品编号随时查看当前仓库的库存，包括商品编号、商品名称、原始库存、进货数目、出货数目、最终库存。退出是退出当前的菜单。


 
  在入库功能中，可以根据商品编号进行货物的入库，增加商品的库存量。

 
  在出库功能中，可以根据商品编号进行货物的出库，减少商品的库存量。

 
  在添加商品中，可以添加仓库的商品，添加的信息包括商品编号、商品名称、原始库存、进货数目、出货数目、最终库存，成功添加时会在下方提示商品添加成功。

 
  在删除商品功能中，可以根据商品编号进行商品的删除，成功删除时会在下方提示商品删除成功。
