Question

请帮我解决以下C ++设计问题

Class Office 
{
    std::list<Employees *> m_Employees; 
    string m_Address;

    void AddEmployee(Employees *employee);
    string GetAddress();    
}
Class SalesOffice : public Office
{
    int  m_TotalEmployees_SalesPerYear;
    int GetSalesPerYear();  
}
Class FinanceOffice : public Office
{
    int m_TotalEmployees_ProfitPerYear;
    int GetProfitPerYear(); 
}
Class BookKeepingOffice : public Office
{
    int m_TotalEmployees_RecordsPerYear;
    int GetRecordsPerYear();    
}


Class Employees
{
    int id; 
    int GetID();
}
Class SalesEmployees : public Employees
{
    int m_SalesPerYear;
    int GetEmployeeSalesPerYear();  
}
Class FinanceEmployees : public Employees
{
    int m_ProfitPerYear;
    int GetEmployeeProfitPerYear(); 
}
Class BookKeepingEmployees : public Employees
{
    int m_RecordsPerYear;
    int GetEmployeeRecordsPerYear();    
}

Class Office有一个Class Employees列表。这种复合关系不能改变。显然，任何类型的Office都只知道员工。问题：SalesOffice的GetSalesPerYear如何访问GetEmployeeSalesPerYear（）注意：我不想在每个办公室里对员工进行强制分类。有关设计和设计模式的任何建议吗？

Answer 1

int GetEmployeeSalesPerYear();应定义为Employee的虚拟方法，返回0，SalesEmployees应重新实现。
