Auto-write asterisks in C++ comments

Question

Is there a way for me to configure my vimrc so that, when writing a multi-line comment in C++, Java, or other languages, like

/* f
 * o
 * o
 */

, I could get the asterisk and space to appear whenever I'm in a comment and press return to start a new line?

If I have not worded my question well enough, please tell me.

Thank you in advance for any help.

Answer 1

That is controlled via 'formatoptions':

:set formatoptions+=r

To also enable this for o and O commands:

:set formatoptions+=o

See all available options at :help fo-table.

Note that this depends on the correct 'comments' setting, but the default already has the right definition for /* ... */ multiline comments.
