erros:
45 book.cpp brace-enclosed initializer used to initialize `livro'
45 book.cpp brace-enclosed initializer used to initialize `livro'
45 book.cpp brace-enclosed initializer used to initialize `livro'
45 book.cpp brace-enclosed initializer used to initialize `livro'

What's the problem with the program?

You can't initialize an array of objects like that.

I saw this way in a forum web site. Could you tell me how I can initialize an array of objects?

Also did you actually write the constructor? Or did you just declare it and hope for the best?

I am relatively sure you can do it like this:

book li[5] = {book(43655, "Eletricidade", "Halliday", 1, 7, 428, "Fisica"), 
                   book(74854, "Plantas", "Sonia", 2, 3, 247, "Biologia"),
                   book(48762, "Crepusculo", "Stephenie", 1, 1, "Ficcao"), 
                   book(12489, "Calculo", "Thomas", 2, 5, "Matematica"), 
                   book(34579, "C++", "Deitel", 1, 3, "Programacao")};

of course it didn´t
just make a little constructor an it will work

i did one with only three arguments and the program still not working

@OP: Copy paste your constructor please.
Maerle (53)
the constructor is alrealdy in the topic

1) They need to be using the constructors like hanst99 stated
2) Your 3rd-5th constructors don't have enough arguments (you are missing a number)
