What's the difference? w and w+

Question

What's the significance with w+ though. Examples, explanations please..

I know that w+ will read the file but wouldn't the file get truncated?
And if reading will come first, what could be the sense— will the contents get saved or smthng, would the user be able to read the contents too or just the program —it would still get truncated

And anyway, is there a way to write on the file without it getting truncated? (not through append)
