coding-style

I was thinking about this when I was starting to set up some code for a new project: are there any rules of thumb for when a method should be part of an object, and when it should be a stand alone function that takes an object as a parameter?

EDIT: as pointed out in a comment, this can depend on language. I was working in C++ when it came to mind, though I'm this is an issue across a number of languages (and would still love to see answers that pertain to them).
