derived class giving error when accessing private variables of base class

I am making a c++ program to store employee's data like name, id, saleamount, commission amount and calculate earning (sales*commission). I am using the concept of inheritance. My base class is 'Employee' and my derived class is 'SeniorEmployee'. When I run the program, the compiler gives me an error that I cannot access the private members of base class. The errors are like this

error: 'std::__cxx11::string Employee::name' is private.

Another error on 2nd line is

error: 'int Employee::id' is private

Again the same error on 3rd line

error: 'double Employee::sales' is private

Following is my code. I have included all files.

File Employee.h

#ifndef EMPLOYEE_H_ #define EMPLOYEE_H_ #include <iostream> #include <string> using namespace std; class Employee { public: Employee(string EmpName, int EmpID, double EmpSales, double EmpComm); void setName(string EmpName); string getName(); void setID(int EmpID); int getID(); void setSales(double EmpSales); double getSales(); void setComm(double EmpComm); double getComm(); double earning(); private: string name; int id; double sales; double commission; }; #endif 

File Employee.cpp

#include <iostream> #include <string> #include "Employee.h" using namespace std; Employee::Employee(string EmpName, int EmpID, double EmpSales, double EmpComm): name(EmpName), id(EmpID), sales(EmpSales), commission(EmpComm) { } void Employee::setName(string EmpName) { name=EmpName; } string Employee::getName() { return name; } void Employee::setID(int EmpID) { id=EmpID; } int Employee::getID() { return id; } void Employee::setSales(double EmpSales) { sales=EmpSales; } double Employee::getSales() { return sales; } void Employee::setComm(double EmpComm) { commission=EmpComm; } double Employee::getComm() { return commission; } double Employee::earning() { return sales*commission; } 

File SeniorEmployee.h

#ifndef SENIOREMPLOYEE_H_ #define SENIOREMPLOYEE_H_ #include "Employee.h" #include <iostream> #include <string> using namespace std; class SeniorEmployee: public Employee { public: SeniorEmployee(string EmpName, int EmpID, double EmpSales, double EmpComm, double BaseSalary); void setBaseSalary(double BaseSalary); double getBaseSalary(); private: double bsalary; }; #endif 

File SeniorEmployee.cpp

#include <iostream> #include <string> #include "SeniorEmployee.h" using namespace std; SeniorEmployee::SeniorEmployee(string EmpName, int EmpID, double EmpSales, double EmpComm, double BaseSalary) : Employee(name,id,sales,commission) { } void SeniorEmployee::setBaseSalary(double BaseSalary) { bsalary=BaseSalary; } double SeniorEmployee::getBaseSalary() { return bsalary; } 

File main.cpp

#include <iostream> #include "SeniorEmployee.h" using namespace std; int main() { string empname = "Fareed Shuja"; int empid = 3978; double empsales = 30.0; double empcomm = 0.99; double basesalary = 50.0; SeniorEmployee emp(empname,empid,empsales,empcomm,basesalary); cout << "Name of the Employee is : " << emp.getName() << endl; cout << "Employee ID is : " << emp.getID() << endl; cout << "Sale Amount is : " << emp.getSales() << endl; cout << "Commission is : " << emp.getComm() << endl; cout << "Earning is : " << emp.earning() << endl; cout << "Employee's base salary is " << emp.getBaseSalary() << endl; return 0; }
