Hello,
i code with qt in console mode but i have an error in the method that should display the members of a simple class.
the error is " erreur : cannot bind 'std::basic_ostream<char>' lvalue to 'std::basic_ostream<char>&&' cout << " type " << type; "
here the .cpp
Qt Code: 
  1. #include "vehicule.h"
  2. #include <iostream>
  3. using namespace std;
  4.  
  5. Vehicule::Vehicule()
  6. {
  7.     nbrPortes = 4;
  8.     type = "Voiture";
  9.     puissance = 5;
  10. }
  11. Vehicule::Vehicule(int portes, QString typeV, int puissanceV)
  12.     :nbrPortes(portes), type(typeV), puissance(puissanceV)
  13. {}
  14. Vehicule Vehicule::operator+(Vehicule const &vehicule)
  15. {
  16.     puissance = vehicule.puissance;
  17.     type = type + " vehicle améilloré ";
  18. }
  19. void Vehicule::afficher() const
  20. {
  21.    cout << "Voiture avec " << nbrPortes;
  22.    cout << " type " << type;
  23.     cout << " et avec une puissane de "
  24.          << puissance << endl;
