On my $0.02,
I am unsure of the lineage of the phrase but it is
meant to mean that it is a humble opinion and worth
very little. I think it becomes more interesting when
you try to understand it in the context of a similar
saying, "A penny for your thoughts". Then it gives
your opinion less value in the eyes of your
conversation partner. So the $0.02 gets two more
meanings, in the sense that when giving your opinion
you say it has much more value than the other person
gave it, or you told them twice as much information
than they were asking for. Either way, just a strange
expression. I sometimes forget that this list is
multi-national.
Back to the C stuff,
While earlier I said it was a matter of preference
maybe it should be more about the true purpose of the
code. Believe it or not, code is there to help the
programmer understand what's going on in a program.
Assembly languages were written to make it easier to
understand/read/modify programs than just binary. C
was created to abstract away from assembly, and so on.
Since the code is there for the programmer, consider
your audience. If you are writing a toy program for
yourself, you any coding style you like. Do whatever
it takes to make it readable for yourself, that way
when you come back to it in 3 years, you can
understand it quickly. If you are writing any program
that requires more than one person or that will be
used/maintained by anyone else, your best bet is to
use standard coding conventions. This ensures that
outsiders can read the source and not be mystified or
annoyed with your coding style. Sorry to ramble on,
but I think this was an important point that nobody
touched upon.
