Novice C++ Programmers post here!

I'm looking to just get a network of email contacts who are also beginning to learn C++... myself I've only learned a few commands so far but I'm hoping to actually get good at the language some day Right now I'm working on a basic DOS text-based role playing game...

As for the email network idea, it would just be cool to be in contact with other beginners so that we can discuss ideas and help each other out.

New to C++ myself, feel free to mail me mixie(at)barrysworld.com

Me too, learning vc++, what with all the fancy MFC and all that. I intend to play with GDI, possibly directdraw/etc and maybe basic opengl, which would be very nifty indeed.

I was send a pdf version of sams' teach yourself c++ in 21 days, which seems good. It's 5mb, I'll upload it somewhere now and post a link.

Sounds great

Thanks Phaxx

Cost me ~ £100 for a set of sams books for VB, wasn't worth it in the end lol.

You might say I am learning,but at a snails pace.Books do little for me,Whatever I read,its not very consistent

Try www.cplusplus.com, they have a tutorial that can get you started

I haven't started doing C++ yet, but seriously intend to. I already know Java, so it's just about learning syntax and classes.

I recommend, starting up a yahoogroups email thingy. You just put everyone's email into this group, and then anyone with some good links or suggestions, just sends an email to the group email, e.g. Cprogramming_eire@yahoogroups.com or something like that, and everyone in the group gets that email. Saves having to keep a load of emails, and no-one (except yahoo) know your email anyway.

hmmmm, I guess I should probably bite right?

That code is above and beyond my current C++ coding level What is it?

think I'm in over my head

Typedef

The point is right?

If netfile is the base and every derived class is a type of netfile then I "could" inherit indefinite classes without the top level execution chaning see?

So say we want to add protocol W - but we have written a whole application around the other classes, what do we do? Well if all of the objects passed to our caller_function are of the same base type then why can't we polymorphically call them @ run time and thus add a class type to aggfile so that as far as all other aspects of the application are concerned we are calling a netfile.some_fn ok? Ergo every function we call is of base class type see? So that we can add madly different types to aggfile but call the appropiate object.parse_header say, ok?

Hmmm I think I might have heard a purist say once that if a language does not support polymorphism then the language is object based, not object oriented, and thus the crux of object orientation was polymorphism, hmmm I might even agree?

Whoops, forgot that I wasn't subscribed to this thread... that would explain the long time it took to post here, sorry all

Thanks for the link Phaxx, and by the way Typedef, you don't seem like much of a C++ beginner

Typedef

hmmm
can i be on the mailing list anyway?

Trojan

no

Lyconix

lol Ever had a shot at making a game Typedef?

I'm actually trying to make a text-based RPG with my miniscule C++ knowledge, so you had better say Yes!

Typedef

sniff.
RPG, hrrmm well s'pose it might be worth a try.
tho
Trojan may be better one to ask with his
Unix systems programming experience/?

Oh and Trojan
I Know where you work
I Know where you live
I mean how may animated dogs wearing glasses are there in Mayo?

Lyconix

You'd be surprised, a lot of the poochies in Mayo have impaired sight!
