C++ people,......

WTF is with seperate function and class declaration and definition ? That's just weird.

 

[Armitage]

Works for me ... I kind of like having the decaration & implementation seperate. Especially when things get big.

I can see that, I just can't see why you don't define the methods within the class.

Like:

ic ... your referring to inline functions. Sometimes if I can do it all on one line, I'll do it right in the class definition:

float getAge(void) {return age;}

But ussually, I find it more readable to just put decalrations & comments on usage in the class definition. Then, most of the time, I just have to look at the class definition (reasonable short & clean) to find the functions I need and how to use them, instead of having it cluttered up with code.

Yeah when you have a class with 14 complex functions it's much easier to see immediately what functions are available to a class. Plus it gives you a chance to put all the declarations in a header file so your users (if you have any) can just look at the prototype of your mehtod.

Same reason for C function declarations/definitions. C++ is derived from C, remember? You can put the method bodies right into the class declaration, but that will make them inline.

Yeah, if anyone else wants to use your code for some other project, they just want to know what functions and classes are available, and what they do. They don't care how they actually work, so it's much easier to just look at a header file with the declarations.

Is that also true when you define C++ templates?

because in c++ you need to include the class definition in source code form, and seperate declaration and definition allow you to seperate the class defintions and method defitions into seperate files, this allows for faster compilation (since the compiler has to compile the method definition file only once where as the class definition header can be included hundreds of times) and hiding of code (if you supply the method defnitions only in compiled form)

are you sure about that?

I don't think that being a template class makes any difference, but I'm not totally sure.

ok, makes sense

I prefer it that way. Besides, it makes compilation faster too.
