final loop

klutez123

So this is the last loop I need for my project. I need to open the file LIBRARIANSHAVE347CATS.DAT and send the info to the screen. Then, it has to search through all entered data, and create a new output file called "bigbook.dat" in which all entered books of over 200 pages have all their data sent to the new file. So far this is what I have: struct card_catalogue //declare a structure then declare all { //the varibles needed for the struct float dewey; string title; string author; int released; int num_pages; enum typeofbook {fiction = 1, nonfiction, reference, pond}; }; int main() { card_catalogue books; ofstream outfile; int i; cout<< "Enter the Dewey Decimal Number please: "; cin>> books.dewey; cout<< "Enter the Title of the book please: "; getline(cin, books.title); cin.ignore(80, '\n'); cout<< "Enter the Author of the book please: "; getline(cin, books.author); cout<< "Enter the Year of Release please: "; cin>> books.released; cout<< "Enter the Number of Pages please: "; cin>> books.num_pages; cout<< "<-----Type----->"<> i; //books.typeofbook = i; if(i == 1) { cout << "You chose Fiction\n"; } if(i == 2) { cout << "You chose Non-Ficiton\n"; } if(i == 3) { cout << "You chose Reference\n"; } if(i == 4) { cout << "You chose Pond\n"; } outfile.open("LIBRARIANSHAVE347CATS.DAT",ios::app); if(outfile) { outfile << books.dewey; outfile << books.title << endl; outfile << books.author << endl; outfile << books.released << endl; outfile << books.num_pages << endl; outfile << i << endl <

That looks great, let us know how your project turns out.

So why are you opening the file and writing to it? :confused: Does that not seem the least bit odd to you?

The code you've shown addresses almost none of your requirements. It allows you to enter data for a single book. You either need to create an array of card_catalogue objects and write out the array after the loop terminates, or you'll need to write out the data in books each iteration of the loop. Where's the loop?

Ever heard of indentation? I don’t even look at posts in which the poster doesn’t make the effort to indent the code.

What does "indent" mean? (I'm spanish :P)

In short it means you write this:

for( ;; )
{
// Stuff here...
}

instead of this:

for( ;; )
{
// Stuff here...
}

Ok, then it is to use the tabulated structure, isn't it? Thanks for the answer
