Hello everybody i intend to make a game but my level is very low in programming but i know some comands I need some suggestions about how to earn more about c or c++ TY all the answers are very appreciated i am new in this ;D and i hope i will learn many things.
-
C++ Tutorial - Google it
-
I recommend learning Visual Basic first - even though c++ is very different you will learn more about programming. C++ is VERY complicated.

Okay i will do as you said but you know where i could find a free version home version or something free for visual basic ;D.TY for the advice.
-
Visual Basic .NET is offered free from MS:
http://www.microsoft.com/express/vb/
-
ty man you are a life saver but it is trial ? ;D
-
Not that I know of, the express version is free- they charge for their Professional,Enterprise, and Team System versions of Visual Studio.
I'm not sure what the limitations are, but it is missing features in the paid versions... I don't believe it expires, or is a trial, though.
-
ty man! Appreciate.
-
I know this sounds stupid but i installed it and i don't find the icon to enter visual studio do you know where i can find it? ;D
-
i found srry for asking such a stupid question ;D.Hehehe
-
Does anione know where i can find a visual basic tutorial :D?

BING?!?!?!

Yes? ???

vb super sucks
http://www.cprogramming.com
C/C++ is 10x more useful
-
and 10x more complicated
-
I don't agree with you VB is infact very good and understandefull for a begginer like me .
For pros :o i agree that c++ and c is better!
-
If you are a student you gan get Visual Studio for FREE from Microsoft Dreamspark along with a lot more software and even Windows Server 2003 and 2008.

OK.
duplicate these with C/C++:

you cannot simply say "VB sucks" you need to back up your argument with real facts.
Also be prepared because I'm ready to respond to any of the common VB criticisms with brash and unnecessarily verbose responses.
-
you keep teaseing me for using something old
well
BASIC is very old and started in the late 1970's (older then CGA)
and it was finally going away and microsoft says
hey i got an idea lets bring BASIC back :)
C++ was much more modern
-
???
VB.NET is a new language.... actually that's why I don't use it.
Visual Basic 6's about box clearly states "copyright 1987-2000", not 1970. the BASIC language as used in Visual Basic 6 is far removed from the one developed at Dartmouth college.
-
c++ was the first language i learned (well i knew how to use ms-dos) and i had little trouble learning it, well i am still a beginner but it still hasnt been to complicated so far...

Are you using ACTUAL C++ or just C? C++ is a superset of C code for the most part.
if your not implementing classes you may as well call it C.
If I may quote some code of the late Paul Dilascia: (this one I duplicated in VB6 :D)

okay, maybe it is a little complex... but why not learn c as a first language then instead of vb6 as smeezekitty said i wouldnt it be more worthwhile then learning vb6 as a first language then learning c++?

Well, learning C precludes creating a windows application for quite some time...
for example, a very basic windows program:

a couple pages. OK, except in VB6... that would require probably 2 or 3 lines. Not sure about .NET, probably just as terse.

I learned C# a while back, self taught with manuals and how-to's. It didn't take long, but I seem to remember that VS .Net was huge.
On the upside I made an image reader/converter in my first week. Then I played around with a few other things.
I don't know if other programming knowledge would have helped or not.
