Derived class linking error

I am working on a programming project from the book I am learning c++ from.

I already have a base class and a derived class given to me (and they work properly, I checked). I am too make a derived class from the derived class.
The derived class I am working on is called Administrator, the class I am deriving it from is called SalariedEmployee.

I think my constructors are working correctly…Now, I have a simple main function that I am using trying to test my work so far.

Code:

---

#include <iostream>
#include <string>
#include "administrator.h"


using namespace std;
using namespace employeessavitch;

int main()
{

        Administrator shane;
        shane.set_supervisor();
        //or shane.print() or shane.info_in()




        return 0;
}

---

It compiles fine, but when I link I get the follow error:

Code:

---

5.obj : error LNK2001: unresolved external symbol "public: void __thiscall employeessavitch::Administrator::set_supervisor(void)"
 (?set_supervisor@Administrator@employeessavitch@@QAEXXZ)

5.obj : error LNK2001: unresolved external symbol "public: __thiscall employeessavitch::Administrator::Administrator(void)"
 
(??0Administrator@employeessavitch@@QAE@XZ)
Debug/5.exe : fatal error LNK1120: 2 unresolved externals
Error executing link.exe.

---

And I get the same error for any function I have created (but replaced with the name of that function in the error). And I have made sure that the other classes the variables are under ‘protected’ and not ‘private’.

Any ideas?
*edit* I just noticed I am also getting a linking error when I try and call the constructor that takes values).....
.h and .cpp from classes follow.

Administrator.h

Code:

---

#ifndef ADMINISTRATOR_H
#define ADMINISTRATOR_H

#include <string>
#include "salariedemployee.h"

using namespace std;


namespace employeessavitch
{




        class Administrator : public SalariedEmployee
        {

        public:


                Administrator();
                Administrator(string the_title, string the_position, double the_salary /*weekly*/, string the_supervisor,
 string the_name, string the_ssn );

                void set_supervisor();
                void info_in( );

                void print();
                void print_check();

       


        protected:
               
               
                string Title;
                string Position;
                string Supervisor;

        };


}//empolyeessavitch


#endif

---

administrator.cpp

Code:

---

#include <string>
#include <iostream>
#include "administrator.h"
using namespace std;



namespace employeessavitch
{


        Administrator::Administrator() : SalariedEmployee(), Title("N/A"), Position("N/A"), Supervisor("N/A")
        {
                //Left blank
        }


        Administrator::Administrator(string the_title, string the_position, double the_salary,
string the_supervisor, string the_name, string the_ssn) :
/* : */        SalariedEmployee(the_name, the_ssn, the_salary), Title(the_title), Position(the_position), Supervisor(the_supervisor)
        {
                //Left blank
        }


        void Administrator::set_supervisor()
        {
                string temp;
                cout << "Enter the new supervisor's name: ";
                cin >> temp;

                Supervisor = temp;
        }


        void Administrator::info_in()
        {
               
                cout << "Enter the administrators title: ";
                cin >> Title;
                cout << "\nEnter the administrators position: ";
                cin >> Position;
                cout << "\nEnter the administrators weekly salary: ";
                cin << salary;
        }



        void Administrator::print()
        {

                cout << "Output data to screen"; //finish later
        }


        void Administrator::print_check()
        {

                cout << "Output data in and info from base classes in check format"; //finish later
        }


}//employeessavitch

what compiler are you using? I used VC++ 6.0 and did not have that problem. But there was one error

Code:

---

        void Administrator::info_in()
        {
               
                cout << "Enter the administrators title: ";
                cin >> Title;
                cout << "\nEnter the administrators position: ";
                cin >> Position;
                cout << "\nEnter the administrators weekly salary: ";
                cin << salary;
        }

---

cin takes the ">>" operator, not "<<"., which will cause administrator.cpp to not be compiled correctly.

did you forget to compile administrator.cpp? It looks to me like you only added the main cpp file to the project.

I am also using VC++ 6.0 (With the latest SP).

Apon further inspection when I try and compile and link the administrator.cpp I get this error:

Code:

---

administrator.obj : error LNK2001: unresolved external symbol "public: __thiscall
employeessavitch::SalariedEmployee::SalariedEmployee(void)"

When I take out my constructors that call the default constructors for the base class “SalariedEmployee” I do not that the two problematic errors.

I am just calling the default constructors for salaried employee:

Code:

---

public:
        SalariedEmployee( );
        SalariedEmployee (string the_name, string the_ssn,
                                  double the_weekly_salary);

---

And silly me yes I did forget to try and compile the .cpp file, which if I had I would have found the previous info in the post out! :0

*edit* sorry for all the crazy new lines in the error....just trying to keep it from making the page 5,000 char long!
