1. separating class declaration (header file) and implementation (sourcefile)    bytes.com

Hello, As you will see from the following code snippets, I'm trying to declare a function object in an header file and implement it in a (different) source file, but my compiler complains (he cannot find the implementation I provided, apparently). (the -c option tells the compiler to don't try to link, just compile). $ g++ -c addition.cpp $ g++ -c ...

Hi, I'm a bit rusty with the wonderful language of c++. I worked with it, maybe 6 or 7 years ago and now I need to knock the dust off. But I was perusing some code when I noticed that this one programmer put the entire class in the header file. I'm not sure what the point to that is. Can ...

Well, you're getting that value since kValues are given too few values in your case (I give it 60 values but I didn't feel like writing all that in the code example here ;)). But if I just use air.h and main.cpp ...

5. When putting a class in a seperate header file...    forums.devshed.com

there is something else to bear in mind. if you have implementation code in a header file, and you include that header file in two separate source files somewhere, and compile those into two object files that you then try to link, unless your implementations are iniline, you will get linking errors due to multiply defined symbols... sounds obscure, but it's ...

You don't specifically need the header file, but you do need the class definition which is typically in the header file (without this, you can't compile). Usually, the header file contains additional includes which are required for the class definition, f.e. windows.h if one of the member variables has type HWND. If the reason you can't add the header ...
