My 5 too. I'd also ask the guy why he doesn't use the damn facilities given to him by C++. He wouldn't have messed this up with better containers, and I bet he doesn't really need the performance "boost" of raw arrays.

I might add that putting some of this stuff into real classes with member functions, etc... would really help us help you. It was damn hard trying to determine if you have a render loop at all.

Seriously. Have an infinite loop render the damn thing and then force close it. Then you can worry about adding code that will exit the loop gracefully.

Gr8t stf

This is very similar to a linked list question posted a couple of weeks ago. Also, it uses the EXACT same codebase (even the "plz" in the question). Where are you guys getting this crappy code to work from? This MUST be a student assignment, but I'd be baffled if the teacher gave you this code to work from.

Why is that you can't use third party libraries? You're going to have to roll more than just your own socket abstraction for different OSes, you'll also need to take care of threading, and you won't be able to fork on windows...

This just sounds like a bad situation to me. If this isn't some wacky school project, boost is basically your best friend and used in plenty of commercial software.

Pretty much all in there.

Hahaha. Awesome!

Ok.

I see double *angle;
I see you call setAngle with a double pointer. I don't see you mention that the OP needs to new the pointer the double pointer points to. Perhaps you meant to imply that, but just taking your parameter change and dunking it into the OPs code is a no go unless he news it there, which is just bad practice anyway. Either way, since he's asking such a basic question, its obvious you should have pointed it out.

No argument there.

Actually sorry about that. I forgot that we use openAL for audio abstraction. Ogg vorbis just provided us with the "raw bits" I was talking about. If the OP's still interested, I'd look into one of the simpler solutions like FMOD.

Yea it can. You just have to be able to load in the raw audio bits. It's pretty versatile. We use it for our cross-platform development framework (ios, android, OSX, Windows, Linux) and openGL for our cross-platform graphics. It's pretty friggin sweet!

Ok. Well if you need it simpler than that, try FMOD.

Look here for an example:

Edit:
And here for the source:
http://www.fmod.org/index.php/download

If you go that route, you'll set some garbage space in memory to whatever setAngle tells it too. You're assigning the angle value to an unitialized pointer. Bad Bad.

I don't think your question is very clear. Are you saying you want to be able to pass in say a file location and then store in your new system?

At the least you'll need to remember what type of file it was originally, so you can restore it to it's original state.

I'm surprised it's even compiling with the line "#include using namespace std;". Even so, is it even printing your first line of output? If it isn't, something else is amiss, because you don't even call on any of your functions before the first call to std::cout <<.

I have the same fear

You got my 5. If he really is talking about comma separated files and even mentioning 3rd party libraries is pretty crazy

OpenXML seems to suggest that that library is open source.

Don't forget, if you're using a cross platform framework, write cross-platform code!

Chage "C:\\Sample.txt" to "C:/Sample.txt" !

I'd give you more than five for the sheer effort you've put into resolving the OP's problem.

Haha my five

Oliver's right. Deleting the elements in the list won't change the size. Also, the OP was calling getCount() outside of the loop (maybe he reposted?). The real problem is he's deleting the same pointer twice.

Both of you got my 5, but note that linked list isn't only for fragmented data in memory.

It's always important to remember what one data structure benefits over another. A std::vector is guaranteed, like you said, to have contiguous memory, but that also means adding into the middle of it takes a high penalty.

Linked lists don't have contiguous memory, but it excels at adding/deleting a reference.

Are you asking how to use a FILE* in the wrapper class QFile?

Google "Class Name 4.7" and you'll get their latest documentation. For example, this is what I get.

http://doc.qt.nokia.com/4.7-snapshot/qfile.html

Looking in that document it is very clear how to use the class.

I disagree that dynamic memory is at the core of C++. In fact, you can go quite far without needing such things. I find that dynamic memory is more a question of performance (do I want to be copying around the data).

I'm just saying, this is NOT a situation that calls for dynamic memory. I'd say that would be a case of premature optimization.

But you are right, eventually he will have to learn. I just don't think the OP is anywhere near ready for that.

Edit: If ever you're having a hard time with heap data, get familiar with boost::smart pointers. They'll save your life on larger projects that go beyond the scope of reading in some lines.

The reason is since the data is const, it isn't dynamic, therefore the compiler KNOWS the size of the memory and doesn't have to dynamically allocate it. Doesn't have to do with computational complexity.

Edit: If the memory allocated isn't dynamic, it is on the stack. Otherwise it is on the heap. This is not a rare scenario, it's just literally the same thing as saying "I have a char array of size 100".

Wow man. Take my 5

Good link, to your article no less! My 5

There's no need to introduce the concept of allocated memory to the OP. He needs much simpler functionality than that. Show him how to use vectors and save his life until he needs to know of such things.

This is the kind of discourse the OP needed. My 5

I gave you a five, because you are of course sir, correct. But doesn't his code show that he's missing some of the fundamentals of programming? I think a discourse on WHY his program is so jacked up would be beneficial to the OP.

For ALL! Me and my buddy have a framework that builds on iPhone, Android, Mac, PC, and Linux. Mind you it takes a lot to abstract everything away, but it's been friggin sweet.

Haha. You know, like the linux manual page where you can look up function defintions.

OMG dude I accidentally gave you a 1 when I meant to give you a 5!

Edit: alright looks like it let me fix it.

Why do you use a template parameter when the pointer can just be of type shape?

Gotta say that OGL is the way to go for cross-platform graphics.

I've heard of schemes that are supposedly pretty portable (running on multiple, multiple, mobile platforms) that use two boolean values (and obviously no assembly)
