Write to goofy@disney.com to get help on this assignment:
Me@myhome.it is my address, while OGRE@darkforest.net is
not mine, but Sherk's, so you shouldn't write to
ogre@darkforest.net
Both <liza@polito.it> and "pamela@polito.it" are fancy
Addresses (and you can write them as Liza@Polito.IT
or 'PaMeLa@pOlItO.IT'
e deve darmi un file di output con tutti gli indirizzi email, senza duplicati, apici, caratteri "< > " e tutti in minuscolo.
Mi da errore alla funzione puts....qualcuno ha un'idea?
