Ovviamente il codice l'ho fatto io, ecco gli errori che il compilatore segnala
copia.cpp: In copy constructor `lista::lista(const lista&)':
copia.cpp:39: request for member `dato' in `scan', which is of non-aggregate type `NODO*'
copia.cpp:40: request for member `next' in `ob->lista::scan', which is of non-aggregate type `NODO*'
copia.cpp: In member function `void lista::creazione()':
copia.cpp:80: base operand of `->' has non-pointer type `NODO'
copia.cpp:81: no match for `NODO& = NODO*&' operator
copia.cpp:4: candidates are: nodo& nodo:
perator=(const nodo&)
