怎样修改这个程序？？？？

Question

程序如下：就是怎样可以实现以下功能；
设计人类（Person类）和医生类（Doctor类），在此基础上，通过增加患者和账单，使它们公用于表示一家诊所的信息管理。
（1）在一条医生记录中，包括医生的专业说明（specialty），如内科医生（surgeon）、儿科医生（pediatrician） 、产科医生（obstetrician）及全科医生（general practitioner）。
（2）Doctor记录还含有诊费（office_vist_fee）。
（3）在一条患者记录中，包括该患者产生的药费(drug_fee) ，患者的诊费（即医生的诊费）。
（4）在一条账单记录中，包括一条患者对象、该患者对应得主治医生、该患者产生的诊费和药费。
（5）应用程序能够显示出诊所中每个患者的信息和对应主治医生的信息。
（6）能够统计出所有患者的总费用。

所有患者的总费用这里没有写出来，加一个static的成员就好了

#include <iostream>

    double get_office_vist_fee() const;

    all_fee += doctor.get_office_vist_fee();

}

    Bill b1(p1, d1);
    b1.show();
    Bill b2(p2, d2);

    return 0;
