仓库管理系统(c语言)

1、作品名称开发者：一、系统背景：本软件能减轻对货物数目管理及价格盈亏等信息处理的工作量以便能快捷及时准确的调整货物的仓储量达到最合理化。 可以使店主不失效率的节省大量精力用于其他 方面 符合当今社会的商业形式而且本软件体积小操作简单是管理仓库的不二选择二、系统简介：设计亮点：三级菜单使操作更简便明了密码操作能有效保证客户信息的安全性独特的dos命令调用使信息存储的实体属性为隐藏且无扩展名大大增大了安全系数数据结构为链表摆脱了数据数量的限制提供三种查看模式并会标出排名退出店主模式时会提示是否保存若选择 yes 着进行保存操作基本功能：在员工模式下可输入卖出货物的名称和数目程序自动在后台进行一系列的
