Thread: Problem calling class function.

Okay, so it's me again

I have declared a vector and function within a class

Code:

vector<Book> Books;
void add_books(vector<Book>&);

I have defined the function within a .cpp file

Code:

void Library::add_books(vector<Book>& b)
{

	//do something
	
}

However, when I call the function, I think I am passing the argument incorrectly. I have tried as such:

Code:

Library::add_books(Library::Books);

But I get the following error:

error C2597: illegal reference to non-static member 'Library::Books

Any wise words of wisdom?

Thanks.

Hello,

Yeah, Library is the class.

Cheers.

Also, I don't see the need for Books to be inside the Library class?
What are you trying to accomplish?

I am following suggestions from an exercise within one of Stroustrups books.

I have already designed a book class and the vector within the LIbrary class is to hold all of the book information.

So I am thinking of creating a Library object that holds all the book objects, within the vector that :
a)have already been created within the code, and
b)the user will be able to add via a Library member function.

So essentially, if I wish to use the add_book function to store books within the Book vector, I will first need to create a Libryary object that is constructed with the Book vector as an argument.

Is that correct?

Thanks.

Thanks for that. Will put that into code shortly.
