binary '=' : no operator defined which takes a right-hand operand of type 'class std::list >::iterator' (or there is no acceptable conversion)
binary '!=' : no operator defined which takes a left-hand operand of type 'class std::list >' (or there is no acceptable conversion)
binary '++' : 'class std::list >' does not define this operator or a conversion to
a type acceptable to the predefined operator
il me dit que les operateur = != et ++ ne sont pas definis et pourtant j'ai bien inclu <list> donc je comprend pas .
