Thread: 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 Supervisor;
