It seems to me that OOP is not as good as procedural programing. I wrote a OO program to display the words "Hello, World!" and it ended up being over 100 lines long, and the first few times I compiled it, there were a million error messages. I really like Java and C++, but I feel more comfrotable with a language like Perl. And Perl''s OO stuff is pretty easy and understandable. All this other stuff is really complicated. Is there any way that OO programming can be made easier? I like the idea of classes and all, but I find that they are extremly hard to implement. BTW, maybe I should mention that I loath the idea of header files, import files, and the like... I don''t why, it just seems messier, even though I know it is supposed to make the code look cleaner, and I guess to some extent it does. But, if you have a long program why waste half a page includeing and defineing things, when you could just as easily implentment them right in your main program file? I''m obviously not talking about standered header files here ie , I''m talking about the header files that you design yourself. I hope that this generates an interesrting dissucsion, since I am very interested in what other programmers think about this stuff. neo88

O''Caml rules. It allows Objective, Functional, and Imperative programming.

And I am better than your countries.

#include <iostream>

int main()
{
std::cout << "Hello, world." << std::endl;

return 0;
}

or even

#include <iostream>

class HelloWorldClass
{
public:
HelloWorld(){std::cout << "Hello, world" << std::endl;};
};

int main()
{
HelloWorldClass HelloObj;
return 0;
}

Exactly what were you doing that it took you over 100 lines??

Also, if you implement everything all in your main program file, it makes it tough to make sense of a file that is 100000+ lines long.

If I have a class Vector3D, and I put the class definition in vector3d.h and the implementation in vector3d.cpp, then I know exactly where to find a function I need, and I can use Vector3D in a dozen programs without having to cut/copy/paste. Throwing everything into one file is a bad way of doing things, and can cause you problems in the long run.

And that is not even to mention compile speed. Say you have a project that is 100000+ lines. You make a tiny change to one function, then rebuild. In the project in which all code is in one source file, you have to recompile every single line. Splitting source up into separate files cuts this compilation time (which can be significant for a large project) down to a fraction, by only recompiling the source file in which you made the change.

My current project just exceed 49000 lines, and I shudder to think about having to work on it further if it were all dumped into a single source file. Golem would die here and now, if that were the case.

I''m thinking it could *maybe*, just *maybe*, be a joke...

That''s what I''d like to know. 100 lines; holy shit^3 ...

Upon second analysis, I''m thinking maybe, just maybe, you might be right superpig.
