用**++单链表数据结构完成c++的学生成绩管理系统++**，此系统的具体功能如下：
本人小萌新一个，遇到BUG是正常现象。并且类与对象写的不太理想。@-@
写了一个Database存放所有数据，但这肯定浪费资源，你们看着改改吧。
cpp
`class DataBase

virtual void run();//多态
void setID(int ID);
void setName(string Name);
void setSex(string Sex);
void setChinese(double Chinese);
void setMath(double Math);
void setEnglish(double English);
void setAverage(double Average);
void setSum(double Sum);
void setNews(string news);
void setSolute(string solute);
void setAccount(string A);
void setPassword(string P);
void setWordprotect(string W);
void setNext(DataBase* next);

double& getChinese();
double& getMath();

};`- 登录系统功能。
- 动画效果进入主界面，可选择教师端或学生端。
