2.能从键盘输入产品的入库信息；
3.能从键盘录入产品的出库信息；
4.将产品按照时间顺序进行存储；
5.能根据产品编号、入库日期修改入库数量；
6.能根据产品编号、入库日期删除入库记录；
7.记录导入产品的管理人员的身份信息；
8.查询指定产品编号的入库记录；
9.查询指定产品编号的出库记录；
10.建立仓库管理系统的账号和密码；

案例代码

以下是一个C++的示例程序，实现了你提供的功能要求。请注意，这只是一个简化的示例，并没有包括完整的错误处理和输入验证。你可以根据自己的需求进行修改和扩展

在这个示例程序中，你可以选择从文件导入产品的入库信息，或者从键盘输入入库信息。你也可以输出指定产品编号的入库记录，并且可以修改或删除指定产品编号和入库日期的入库记录。注意，产品信息和仓库信息在程序中是硬编码的，你可以根据需要进行修改。
