fallos en mi código

[lexell]

Hola, estoy escribiendo un programa en C++ para la facultad, es de tema libre por lo que tengo libertad para cambiar las cosas, pero me da un error que no consigo solucionar por mucho que busco y cambio código, os dejo el código completo a ver si alguien me puede sacar de este apuro, muchas gracias por vuestra ayuda,

Código C++:

//.h
 
#ifndef _PROJ_
#define _PROJ_
 
#include <string>
#include <iostream>
 
struct vehi
{
    public:
    virtual void print (std::ostream& stream)const=0;
    virtual vehi * clone () const=0;
    ~vehi(){}
}
 
struct vehicle
{
    public:
    vehi* ref;
    
    vehicle (const vehicle& s ) : ref (s.ref->clone()){}
  vehicle ( const vehi& s) : ref(s.clone()){}
  
  void operator =  (const vehicle& s)
  {
    if (s.ref != ref)
    {
      delete ref;
      ref = s.ref->clone();
    }
  } 
 
  void operator = ( const vehi& s)
  {
    if (&s != ref)
    {
      delete ref;
      ref = s.clone();
    }
  }
  
  ~vehicle()
  {
    delete ref;
  }
  
}
 
struct car : public vehi
{
    public:
  std::string type;
  float weight;
    unsigned int wheel;
  unsigned int passanger;
  unsigned int motor;
  
    car () : wheel(0),passanger(0),motor(0),type(""),weight(0.0){}
    
  car(unsigned int wheel, unsigned int passanger, unsigned int motor, std::string type, float weight) 
    : wheel(wheel),passanger (passanger),motor (motor), type(type), weight(weight){}
    
  ~car(){}
  
  virtual vehi * clone () const
  {
    return new car(*this);
  }
  
  virtual void print( std::ostream& ) const
  {
    std::cout << "CAR:\n\nWheel: " << wheel << "\nPassanger: "<< passanger << "\nMotor: "<< motor <<"\nType: " << type << "\nWeight: " << weight << "\n\n";
  }
}
 
struct motorbike : public vehi
{
    unsigned int wheel;
  unsigned int passanger;
  unsigned int motor;
  std::string type;
  std::string brand;
  
    motorbike () : wheel(0),passanger(0),motor(0),type(""),brand(""){}
    
  motorbike(unsigned int wheel, unsigned int passanger, unsigned int motor, std::string type, std::string brand) 
    : wheel(wheel),passanger (passanger),motor (motor), type(type), brand(brand){}
    
  ~motorbike(){}
  
  virtual vehi * clone () const
  {
    return new motorbike(*this);
  }
  
  virtual void print( std::ostream& ) const
  {
    std::cout << "MOTORBIKE:\n\nWheel: " << wheel << "\nPassanger: "<< passanger << "\nMotor: "<< motor <<"\nType: " << type << "\nBrand: " << brand << "\n\n";
  }
}
 
struct truck : public vehi
{
    unsigned int wheel;
  unsigned int passanger;
  unsigned int motor;
  unsigned int charge;
  float weight;
  
    truck () : wheel(0),passanger(0),motor(0),charge(0),weight(0){}
    
  truck(unsigned int wheel, unsigned int passanger, unsigned int motor, unsigned int charge, float weight) 
    : wheel(wheel),passanger (passanger),motor (motor), charge(charge), weight(weight){}
    
  ~truck(){}
  
  virtual vehi * clone () const
  {
    return new truck(*this);
  }
  
 
  virtual void print( std::ostream& ) const
  {
    std::cout << "TRUCK:\n\nWheel: " << wheel << "\nPassanger: "<< passanger << "\nMotor: "<< motor <<"\nCharge: " << charge << "\nWeight: " << weight << "\n\n";
  }
}
 
 
std::ostream& operator << (std::ostream& stream, const vehicle& ve)
{
  ve.ref->print (stream);
  return (stream);
}
 
 
#endif
 
 
 
//.cpp
 
int main( int argc, char* argv [ ] )
{
    std::list< vehicle > l;
  car c (4,5,1600,"tourism",1200);
    motorbike m (2,2,600,"race","Honda");
    truck t (8,2,5000,10000,8000);
 
  
  l.push_back(c);
  l.push_back(m);
  l.push_back(t);
  
  for( std::list< vehicle > :: const_iterator
        p = l.begin( );
        p != l.end( );
        ++ p )

    std::cout << *p << "\n";
  }
}
 

Errores:

proj.h:146: error: expected initializer before ‘&’ token
proj.cpp: In function ‘int main(int, char**)’:
proj.cpp:22: error: no match for ‘operator<<’ in ‘std::cout << p.std::_List_const_iterator<_Tp>::operator* [with _Tp = vehicle]()’

bueno por ahora este es mi codigo, espero que me podais ayudar, muchas gracias de antemano

salu2!!

bueno al fin lo arregle.... era un fallo de lo mas tonto, olvide los ; al final de cada struct
