思维导图：（我是根据这个图做的，自己可能思路没这么清楚，这里建议大家写代码的时候也先进行构思，因为这是一个很好的习惯，写好思维导图之后，写代码按照功能一块一块填好就行了，这里用到了多态，容器，以及一些基本的c++功能，因为最近就在学这些，然后就实践一下，感觉c++的面对对象编程在思路上的确比c的面对过程编程要稍微显得清晰一些，嗯，可能分的块更加清晰了把。分文件的编写会让条理更加清晰。） 所有文件如下： 这里将管理员，教师和学生分为3个子类，父类是一个包含他们公共信息的identity类，可以将他们的共性放在里面，然后个性写在子类里就行了，父类是写了个虚函数，所以子类里面一定要重载，最后按功能填写代码就行了，这里注意文件打开后要进行close，一些小细节就不说了下面上代码。 头文件： Identity.h（身份类头文件）
