[问题描述]
    设计一个院校管理程序.
    学生包括姓名,性别,身份证号码,生日,年龄,地址,学号,宿舍号,专业,年级的输入输出;
    教师包括姓名,性别,身份证号码,生日,年龄,地址,公寓,每天工作时间,每月薪水,授课专业,所从事的科研名称,所带研究生数目的输入输出;
    工人包括姓名,性别,身份证号码,生日,年龄,地址,公寓,每天工作时间,每月薪水,工作类别的输入输出.

[算法分析]
    设计一个RECORD类,它包括姓名,性别,身份证号码,生日,年龄,地址的输入输出,然后从RECORD类派生一个STUDENT类,实现学生数据学号,宿舍号,专业,年级的输入输出,从RECORD类派生一个STAFF的中间类,实现公寓,每天工作时间,每月薪水的输入输出,再从STAFF类派生出PROFESSOR类和WORKER类,分别实现教师授课专业,所从事的科研名称,所带研究生数目和工作类别的输入输出.下图反映了这些类之间的关系.
