Hi Vili,
I come from a procedural background. I started with COBOL. I have made
several fits and starts at other languages. I have not yet found a way to
get over the OO learning curve. One reason is that I have not found a
project that really interests me. The other is that the books I am reading
teach the procedural side of languages like Python and then move into OO.
It seems like I would need to come up with a relatively big project to make
it worth doing in OO. I keep saying to myself that whatever I am thinking
of doing at the time is easier to do procedurally. I never find a
compelling enough reason to do OO. I read about how great it is in the
programming material I look at, but some how, that never translates into my
learning because I get intimidated by all the setting up of all the objects
just to get something simple done. There has to be some middle ground in
all of this somewhere.
Finally, I don't know enough to be able to tell if whatever project I am
thinking of doing is best to do in procedural or OO.
And one more thing while I'm rambling. It seems like OO really doesn't
model the real world even though the OO material I have read to this point
says it does. I should probably save that for another email though.
Thanks.

Hi Arnold,
I'm not sure Java might be the best start, either, although it is widely
popular. In our Uni in Finland Java is used mostly procedurally and
there's a separate course on object oriented programming, also in Java.
The authors of how to Think like a Computer Scientist, the PYthon
edition. argue that one of the strong points of multi-paradigm langs is
that you don't have to cover objects first. They clame it is hard to
teach object first, since to really understand them one needs knowledge
of variables and scope, functions, operators, parameters and all the OO
jargon for relatively non-magical things. WIth a multi paradigm language
hello world is just like:
puts "hello world"
Or something like that, and you can start with very simple procedural
concepts, and cover functions, objects etc... when people are ready to
tacle them. I still recall trying to understand OOp from a procedural
background and all this talk of objects sending messages to each other
and having contracts just threw me off. But statements like basic
objects are just like structs with syntactic sugar for calling functions
taking structs, and no direct access to struct members allowed, are
closer to a procedural programmer mind set, and are more descriptive,
too. There's even a book about object oriented programming in c, though
I wouldn't start with C. Perl's object orientation heavily relies on
procedural concepts and references, too, but Perl is a bit too
specialized to start with I'd say e.g. no separate float, string and int
handling, plus abnormally strong string processing in the core. I'd
start out with a conventional, statically and strongly typed language at
any case, since it is, in my view, easier to see some advantages of both
static and dynamic typing, if you have learned static typing first. but
that's just my experience, I'm just a student.
