错误重复：私人成员的继承？

这是错的？我认为私人成员不是从基类继承的：错误重复：私人成员的继承？

“类HourlyEmployee的定义没有提到成员变量名称，ssn和netPay，但HourlyEmployee类的每个对象都有成员变量namedname，ssn ，和netPay。成员变量名称，ssn和netPay从Employee类继承。“

//This is the header file hourlyemployee.h. 
//This is the interface for the class HourlyEmployee. 
#ifndef HOURLYEMPLOYEE_H 
#define HOURLYEMPLOYEE_H 

#include <string> 
#include "employee.h" 
using std::string; 


namespace SavitchEmployees 
{ 
class HourlyEmployee : public Employee 
{ 
public: 
    HourlyEmployee(); 
    HourlyEmployee(const string& theName, const string& theSsn, 
    double theWageRate, double theHours); 
    void setRate(double newWageRate); 
    double getRate() const; 
    void setHours(double hoursWorked); 
    double getHours() const; 
    void printCheck(); 
private: 
    double wageRate; 
    double hours; 
}; 
}//SavitchEmployees 
#endif //HOURLYEMPLOYEE_H

其他头文件：

//This is the interface for the class Employee. 
//This is primarily intended to be used as a base class to derive 
//classes for different kinds of employees.
