Je ne comprends pas pourquoi mon compilateur me donne ces erreurs:ne peut pas déclarer un pointeur vers 'classe const & FOO' erreur
brain.cpp:16: error: cannot declare pointer to ‘const class FACT&’

J'utilise g ++ 4.4.3 je peux comprends pas pourquoi il ne considère pas « FACT » être un type de données
Je pensais que la façon dont était vous avez fait le constructeur de la copie – noah
@noah: C'est fait sans le '*'. – sth
