1: 项目需求
2: 功能实现的具体思路为:
(1) 经行职工信息的读入，用while循环进行读入，对于职工信息类型的设定方便起见除年龄和薪资用int类型其他信息都用string类型，职工信息用ostream 流写入txt并将信息保存在txt文件中，打印职工信息由于c++读文件方式不方便所以用c语言方式读文件，文件读取以后将文件中读取的信息加载到vector容器中后打印在终端窗口，其他功能的实现也是将文件中的信息读取到vector容器中，后用vector容器中的重载函数进行功能的实现；?
3：头文件的编写的具体实现

}6：功能3，4，5，6，的实现都是将文件中的信息加载到vector中，并且使用的都是保存了worker这个类对象的同一个容器（假如先实现工能3，将信息加载到vector中后功能3结束以后，功能3使用到的职工信息依然在vector这个容器中，所以使用完一个函数后要将vector中的信息清理完全，不然会影响下一个函数的使用）。
7；在实现功能5的时候会使用到vector容器的重载函数（ worker.erase(worker.begin()+i);）使用完以后返回的是下一个迭代器指向下一个对象，所以在使用使用for循环遍历容器的时候因注意for (int i = 0;i < worker.size();i++)? 中i++具体放在哪个位置比较合适。
8：这是本人在编写程序的时候发现的坑如果有什么错误请批评指正。
