A problem with a graph

[Dax]

Hi,
I'm using boost library, I want to create a graph of a library in c++,
and, for example, every leave is a book, inside it there are some
variables, like title, if is available, description, number of archive etc
etc.
I can do it?

Thanks

Daniele

Why are you asking us? I think it's a question for you yourself to
answer. Can you do it?

As a side note: in case you meant to ask whether it was possible to
do at all, then the answer is "yes, it's possible".

You've described some nodes, but no paths between them. What you've
described doesn't sound like a graph at all, but I suspect you've left
out the key detail.

What you've described so far sounds like a vector<Book>, and not a
graph.

All nodes are linked.
I need a graph, but that what I need to know is if it's possible to have
informations about these nodes.

What, every book is linked to every other book directly!? That gets
very memory hungry, very quickly as the number of books increases.

You can attach arbitrary properties to vertices and edges.

I don't understand why you need a graph.
A book is an object with attributes, such as:
title
author
publisher
ISBN
maximum number of pages
Dewey Decimal Number

A library, card catalog, etc. is a container of books.

A view is a list of books, ordered by a given attribute.

I still don't see where the graph comes in. Please enlighten
me. I'm working on a program which has a database of
references, such as books, magazines, newspapers, etc.

What does a link represent?

A graph is quite unusual given the assignement information you
have given up to now. At the moment nobody can see why a graph
would be needed and why a simple std::vector or std::map would
not be sufficient. But this may be because of lack of knowledge
on our side.

Sure. Why not? If you want to include the name of the dog
of the grandma of the author, so be it. You are the programmer.
