C++

[IAMTHEEVILBEAN]

Hey anyone know c++...i am starting to learn it now and wondered if I could get any pointers....

[87x]

umm study.... lol.. and no i dont know it.. just stick to your book and give up your whole non computer life to keep trying to learn it

[IAMTHEEVILBEAN]

Hmmmm give up whole non computer life.....*thinks* what is this non computer life you speak of

[Anonymous]

I think you should start out easy...like with VB becuase C++ is hard.

[SotN]

What other languages do you know?

[Valek]

I agree with Yoshimaro, learn VB since it's a lot easier than C++, then go to C++. Or, if you just master C++, Visual Basic is just going to seem like childs play, so whatever.

[makaveli121212]

i think c++ is easy; devlop a personal style and stick with it, that will help alot; you could ask vxdx he wrote snake and pong in c++, probably the best at c++ that i know

[Freak83]

I want to know C++ so badly... you see, Natural-Selection was made with C++

[flipmaster99]

C++ isn't that hard to learn.. in my opinion Java is better, C++ is too lenient in the things you can do sometimes (which can be good or bad).

If you have any general questions about C++, i can help you out there.

[FFRdaveg]

When your learning c++ it's good to look at the code in the book and understand whats happening for example
Some C++ books are heavy n useless information so when you get the basic idea of what something does I recommend you right it down so you don't forget with all the other stuff in the book.
cout and cin are important for beginners. it's not that hard to learn if your in algebra or above thats all i have to say

that's an early version of pong I wrote.

As for tips, make sure you know why what you write works, it will help in the long run. Also, if you ever think of a problem that you wish could go faster (lets say for a math class or something) write a program for it. It will help you get comfortable with the basic ideas.[/code]

[flipmaster99]

Wow, nice job on the Pong program. You say that's an earlier version of it.. does that mean you have a more efficient way or what?

Out of curiosity, how old are you?

Wow, nice job on the Pong program. You say that's an earlier version of it.. does that mean you have a more efficient way or what?

Later versions were more efficient, had more features, more accurate ball physics and such.

I'm 16.

I have a pretty good snake too. I just don't know where it is.
