vector to output file?

[noonmoon]

I am unfamiliar with vectors but I still decided to use them in my project.

I am trying to output to .txt files from a vector, and i'm lost.

Heres what I have so far but it wont even compile.

vector<Book>::iterator ob(outbooks, '\0');
   for ( ob = booklist.begin(); ob != booklist.end(); ++ob ) 
   {  
      copy(booklist.begin(),booklist.end(), ob);
   }

please help.
Thank you.

vector<Book>::iterator ob;// this ->(outbooks, '\0'); has nothing to do here
   for ( ob = booklist.begin(); ob != booklist.end(); ++ob ) 
   {  
      copy(booklist.begin(),booklist.end(), ob);
   }

Thank you,

But this is not writing to the output file.
Heres my code:

void Library::addBook()
{
	ofstream outbooks("books.txt", ios::out);
	string title, author;
	int isbn;

	cout << "Enter book's title: " << endl;
	getline(cin, title);
	
	cout << "Enter author's name: " << endl;
	getline(cin, author);
	
	cout << "Enter book's ISBN number: " << endl;
	cin >> isbn;

	//cin.ignore( numeric_limits <streamsize> ::max(), '\n' );

	inbooks = new Book;
	inbooks->setTitle(title);
	inbooks->setAuthor(author);
	inbooks->setISBN(isbn);
	booklist.push_back(*inbooks);
	cin.get();	
   
   //does not write
   vector<Book>::iterator ob;
   for ( ob = booklist.begin(); ob != booklist.end(); ++ob ) 
   {  
      copy(booklist.begin(),booklist.end(), ob);
   }
}

Of course not. You never tell it to do it.

Also, inbooks is leaking.

[noonmoon]

Thank you, stopped the leakage.

this kind of does it, but it writes the last book, how every many times the list count is.

	vector<Book>::iterator ob;
   for ( ob = booklist.begin(); ob != booklist.end(); ++ob ) 
   {  
          outbooks << title << endl;
	  outbooks << author << endl;
	  outbooks << isbn << endl;
   }

I believe I need to count each book before writing them in, maybe a nested loop??

[ne555]

You want to print the book that you are on
outbooks << ob->title << endl;

[noonmoon]

aha!

thank you!
