Yes, that's true, I hadn't considered templates. But as you said, it's true like 99% of the time, so hopefully it's just a small "by the way".
Frankly, all the standard headers scare me. There's just so many macros and crazy stuff... I'm glad I don't have to deal with them most of the time.
And I had no idea that c and c++ headers were differentiated (although it certainly makes sense that they should be). Is that a "rule", i.e., recommended by some sort of semi-legitimate authority, or just common practice? It doesn't really matter, I suppose, I'm just curious; I'll go change all my headers now.

The C++ Standard does not AFAIK mention any header file extension, and the standard headers have no extension. However, .hpp header files are used by Boost, which was formed by members of the C++ Standards Committee Library Working Group to establish "existing practice" and provide reference implementations of new C++ libraries for eventual standardization. In other words, .hpp is almost, but not quite, "official".

From what I understood, it was more "standard" to not actually label a c++ header file with an extension, just as the STL headers are labeled.

It is my understanding that the extensionless style of the standard library headers is not intended to be used by ordinary programmers. The reason it exists is that the standard library headers don't have to be actual files. Their contents could be hardcoded in the compiler for example.

*Shrugs* One of my professors mentioned the style to me. Not that professors are always rote perfect about things (especially industry standards), but this guy is fairly active in Industry.

anyway, i figured out some of the problems...its my directories do all of my headers and libraries...but i got one linker error now...it says "g++: No input files"
any ideas? (BTW: im using Dev-C++ 4, not 5)
if this doesnt work out w/directx, then im just going to buy a compiler

What it means should be obvious, what causes it less so. Can you post the command line for g++?

Why not try using SDL or Allegro instead? I wouldn't touch DirectX directly unless I really had to, because the API for SDL is so much nicer. (Of course I wouldn't touch Dev-C++ either; I edit with VIM and compile with both MinGW and Visual C++ from the command line.)

sorry, but i have no idea what G++ is, or mingw....(my teacher never taught us that stuff) so i cant help you on your question about it
i dont really want to go to allegro or SDL because i already started up on directX...im not having any trouble learning, its just i want to program some examples so i can actually make something later (or now)
i saw Visual C++ .net at Compusa yesterday for $110 (BTW...is .net a web programming part for it?)

Dev-C++ is not a compiler, it's an IDE (integrated development environment) front-end for gcc (GNU C compiler). There are two versions of gcc for Windows: MinGW and cygwin. IIRC Dev-C++ comes with MinGW. g++ is gcc in C++ mode.
When you ask Dev-C++ to compile and link your program, it calls gcc to do the actual work. It does this by passing through a command line, since gcc is a command line utility. I think Dev-C++ has some way of telling you what the command line is - either in the project settings or in the build window - but I haven't used Dev-C++ in ages, so I'm not sure where exactly.

I also learned DirectX. Then I found out about SDL, tried it, and I haven't gone back to DirectX since. So, yes, it's definitely possible to learn DirectX, and no, I don't think it's a good idea. Error handling in DirectX is particularily nasty, as just about every function can return a wide variety of error codes which must be handled. But whatever, it's your life.

.net is the latest version of Visual C++, also called version 7. It refers to the .net framework (which is a totally useless Java-style virtual machine, and has nothing to do with the internet), but you can still compile normal C++ programs normally. Watch out for the standard or academic edition of Visual C++, which has optimizations disabled. If you want to generate fast code, you need at least the professional edition.

ooh, i see now. well, i have a book on directX (and RPG's ) called
"Programming RPG's with directX" by Jim Adams. so im not learning off of some guy that has no name on the internet. thanks for everyones help (and i think i'll go with VC++....whenever i get money...)
