[Serialization](http://en.wikipedia.org/wiki/Serialization) is what you're looking for. — JBL, Jun 25 '13 at 12:29
that class won't compile without `};` you might look up object serialization on google — hetepeperfan, Jun 25 '13 at 12:29

There's no builtin solution to write an object into a file. You have to serialize it.

Read this answer if you want more informations.

What you're looking to do is called serialization. One option is to write your own method that simply writes every value in the object to disk in a format of your own choosing, or you can use an external libray. You can find more information in this answer.

What are you asking about is object serialization: http://en.wikipedia.org/wiki/Serialization

I recommend reading this question Is it possible to serialize and deserialize a class in C++?

and this page http://www.parashift.com/c++-faq-lite/serialization.html
