I strongly suggest that you post COMPLETE examples. When you
are writing at a vague level and don't know the syntax of
the language precisely, let alone the semantics, it gets
VERY hard to guess what your misconceptions might be. You
will find that you get much better results if

(a) you write a complete program

(b) you compile it

(c) you try to figure out the error messages you get

(d) if you can't figure out the error messages, post the
ENTIRE (smallest possible) program that generates the
error messages, and ask.

I often find that students think they know something and so
they pose a question in a garbled form, that depends on this
knowledge, the only trouble is, the knowledge happens to be
wrong.

If you don't post a complete example, you may easily have
the phenomenon of people being confused by what you write,
and then adding to the confusion by answering something
different than what you thought you were asking.
