error iostream

This code is giving me a odd error dont know why.It says 42 c:\dev-c_~1\employee.cpp
no match for `ostream & << {unknown type}'

77 c:\dev-c_~1\include\g__~1\iostream.h
candidates are: class ostream & ostream::operator <<(char)

Code:

---

#include <iostream>
#include <cstdlib>

using namespace std;

class Employee{
      int age;
      int yearsOfService;
      int Salary;
      public:
            Employee();
            int getAge();
            int getYears();
            int getSalary();

            void setAge(int);
            void setYears(int);
            void setSalary(int);

            ~Employee();
};

int Employee::getAge(){ return age; }
int Employee::getYears(){ return yearsOfService; }
int Employee::getSalary(){ return Salary; }

void Employee::setAge(int num){ age = num; }
void Employee::setYears(int num){ yearsOfService = num; }
void Employee::setSalary( int num ){ Salary = num; }




int main()
{
 Employee t;

 t.setAge(18);
 t.setYears(2);
 t.setSalary(2000);

 cout << "Employee's age " << t.getAge <<", Years of service " << t.getYears
      << " and Salary " << t.getSalary << endl;

      system("PAUSE");
      return 0;
}

CHANGE
cout << "Employee's age " << t.getAge <<", Years of service " << t.getYears
<< " and Salary " << t.getSalary << endl;
TO
cout << "Employee's age " << t.getAge() <<", Years of service " << t.getYears()
<< " and Salary " << t.getSalary() << endl;

and another problem is that you haven't implemented Employee() or ~Employee()

That's correct, because getAge(), getYears(), ... are functions that return values which will be printed, so you have to call like this cout << getYears()
