职工管理系统（list容器）

　　今天学了c++的容器，然后就把之前的职工管理系统重新拿出来做了一遍，这次我是用list容器做的，vector的操作其实也是有着异曲同工之妙，vector首先是解决了数组的一个大缺陷------有上限，但是它本质上还是数组，只是动态分配内存了而已，还有一点不得不说c++比c强大的地方了，c里面如果要对数组插入删除的时候还是不怎么方便的，但是c++把这些操作封装在了一起，使用的时候只需要调用一下函数而已，将这部分的时间节省了下来，留下更多的时间来处理其他事情。list和之前的链表感觉差不多，也是将一些链表的操作封装起来了，原理还是一样的，不过还是要感谢这些把数组链表操作封装成一个一个库的那些人，正如牛顿所言，我看的比别人远，那是因为我站在巨人的肩膀上！感谢前辈们的贡献吧。以下的是代码：
