ciao ragazzi ho scritto un semplice programmino in c++ per testare l'uso dei puntatori e la suddivisione in più file di un progetto. Io utilizzo dev-c++ su windows vista (ovviamente ben configurato). Vi posto i file del mio progetto e l'errore che mi da in compilazione sperando che qualche anima pia mi illustri il problema. Grazie in anticipo.

l'errore riportato è:
codice:
3 C:\Users\Gabriele\C++\Department.cpp In file included from ../Users/Gabriele/C++/Department.cpp 
8 C:\Users\Gabriele\C++\Department.h expected unqualified-id before "using" 
8 C:\Users\Gabriele\C++\Department.h expected `,' or `;' before "using" 
7 C:\Users\Gabriele\C++\Department.cpp expected unqualified-id before "using" 
7 C:\Users\Gabriele\C++\Department.cpp expected `,' or `;' before "using" 
 C:\Dev-Cpp\Makefile.win [Build Error] n\make.exe: *** [../Users/Gabriele/C++/Department.o] Error 1
I file che fanno parte del progetto sono:

1) Department.cpp
codice:
#include <iostream>
#include <string>
#include "Department.h"
#include "Employee.h"


using namespace std;

Department::Department(string n)
{
     name = n;
     receptionist = NULL;
     secretary = NULL;
}

void Department::set_receptionist(Employee* r)
{
     receptionist = r;
}

void Department::set_secretary(Employee* s)
{
     secretary = s;
}

void Department::print() const
{
     cout << "Name: " << name
          << "\nReceptionist: ";
     if (receptionist == NULL) cout << "None";
     else cout << receptionist->get_name() << " " << receptionist->get_salary();
     cout << "\nSecretary: ";
     if (secretary == NULL) cout << "None";
     else cout << secretary->get_name() << " " << secretary->get_salary();
     cout << "\n";
}
2) Department.h
codice:
#ifndef DEPARTMENT_H
#define DEPARTMENT_H

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


using namespace std;

class Department
{
      public:
             Department(string n);
             
             void set_receptionist(Employee* r);
             void set_secretary(Employee* s);
             void print() const;
             
      private:
              string name;
              Employee* receptionist;
              Employee* secretary;

}

#endif
3) Employee.h
codice:
#ifndef EMPLOYEE_H
#define EMPLOYEE_H

#include <string>

using namespace std;

class Employee
{
      public:
             Employee();
             Employee(string employee_name, double initia_salary);
             
             void set_salary(double new_salary);
             
             string get_name() const;
             double get_salary() const;
             
      private:
              string name;
              double salary;
}

#endif
4) Employee.cpp
codice:
#include <string>
#include "Employee.h"

using namespace std;

Employee::Employee(string employee_name, double initial_salary)
{   
      name = employee_name;
      salary = initial_salary;
}

string Employee::get_name()
{   
      return name;
}

double Employee::get_salary()
{
      return salary;
}

void Employee::set_salary(double new_salary)
{
     salary = new_salary;
}
5) main.cpp
codice:
#include <iostream>
#include <string>
#include "Employee.h"
#include "Department.h"

using namespace std;

int main()
{
    Department shipping("Shipping");
    Department qc("Quality Control");
    Employee* harry = new Employee("Hacker, Harry", 45000);
    shipping.set_secretary(harry);
    Employee* tina = new Employee("Tester, Tina", 50000);
    qc.set_secretary(tina);
    qc.set_receptionist(tina);
    tina->set_salary(55000);
    shipping.print();
    qc.print();
    
    return 0;
}
Grazie mille e scusate la lunghezza del post ma era per dare tutte le info possibili sul codice che ho scritto.
