2、位奖，对专职教师按其职称和月任课时数计发业绩奖，对既有管理工作又兼授课的人员按岗位奖加月任课时数乘某系数之和为奖金数。我们可以建立一个抽象类，具有员工的基本数据成员，计算月奖金和显示信息的成员函数。由于不同人员的奖金计算方法不同，所以将这两个成员函数声明为虚函数。以抽象类为基类派生出三种不同人员类，有派生类对月奖金和显示信息函数进行重载。主函数实现动态调用，计算个人员的月奖金。1.2 程序功能说明，程序结构图管理人员兼教师类：奖金=固定岗位奖+上课时间*每小时奖金+级别（15级）*某系数；专职教师类：奖金为上课时间*每小时奖金数+级别（15级）*某系数；校园管理人员类：奖金发放固定岗位奖+级别
