I agree! In the passed I've inherited some large and maintenance unfriendly projects (in C). One required that if you made a change in one of three arrays you had to make changes to the other two, which where in different files. I combined them into one large array and provided a set of functions to access the data. In that way when a new feature had to be added, I only had to go to one place to make the changes. All the functions, that used to have direct knowledge of there respective arrays, no longer needed to have that knowledge, to function without change. The result: code that could be modified in 15-20 minutes, as opposed to hours.

Nope. I am the one who replies without a CListCtrl!
Also, you will see that 3 people did put CListCtrl

bug free is a stupid option, no one intends to write a buggy application, it all depends on the skill of the progrrammer wheather he is able to produce bug free application...
A programmer can not aim for fast code with bugs!!!
I vodet for code that uses least resources, as i have been programming since 8086 machines, writing TSR software that leaves very less footprint in the 1mb memory has taught me to write least resource consuming apps and free up memory when not required.

I agree.
What is "a bug free" program? If we write a complex application, nobody(not even Microsoft) has the resource to test for all possible test values, hence it is highly unlikely we have a bug free program.
I am glad that the poll shows that maintable code is number 1 choice, otherwise I would be worried.

I personally find it more efficient to just get the bug-free code out of the way first. In my case, this would be a class or certain functions hacked together -- certainly not very pretty to look at.
But after the class has been tested, I rewrite it in a more elegant, understandable fashion. This includes changing the comments to be somewhat more descriptive of what's actually going on. Often when it's rewritten in this easier-to-understand fashion, it's easier to optimize for speed or footprint.

Why rewrite something that works and have been tested?  You'll just have to retest it again.. it certainly doesn't sound like a more efficient way as opposed to writing "pretty" code from the beginning.

There's an argument for doing a quick 'spike' implementation not following the usual standards of error checking, coding, etc, in order to check whether an approach works.
I'm incapable of doing this: I always end up doing a real implementation, even for a spike.
Stability. What an interesting concept. -- Chris Maunder

It takes considerably longer (in my opinion) to do it that way instead of making it ugly but bug-free the first time. If a file can be made functional - though not optimized or understandable - quickly, then other developers can immediately take that and begin using it in code. In this manner, you can continue to optimize the original file for later inclusion while simultaneously giving others access to its functionality so that they can test their own components.
Also, retesting something like this isn't as hard as it may seem. Remember that functional code is already there and fresh on your mind. All a developer has to do is clean it up a bit and perhaps add safety checks, i.e. try-catch statements.
But as you said, Jörgen, writing pretty code from the beginning is always preferable.  If a coder can pull this off, I tip my hat to him, but this is a feat I've rarely seen accomplished. This isn't to say that we shouldn't follow good programming practices, though, like documenting functions and their parameters from the get-go.
Thanks for your reply!

if a function has a well defined interface;this comes in, this comes out, then rewriting it to acctualy make the code more understandable or faster or whatever, makes sence. For the user it should make no difference. Though it is not always so. Calling external resources that may introduce new errors.... etc etc

This is also definitely an error source. Function A written and tested, programmer tidies it up.
As it was only some cosmetic changes, no proper retesting. BANG - ugly bug.
I've seen it far too many times (and even done it myself  ).

Bug free? Are you kidding?! Thats almost impossible. 
If you write code that is maintainable, as you discover bugs, you can fix them easily. Some aspects of maintainable code are readability, well thought out, organized, and effecient. Each of these contribute to maintainability.  Funny, but it looks like these cover almost all the other options except maybe speed. 
If you learn to write maintainable code from the get-go, you don't have to ever re-write.  Instead, you maintain the code. (Some of us call this refactoring.)

Elegance is my #1 goal, but it doesn't correspond precisely with any of the items on the list.
I'm not interested in readable code if it's not elegant. Contrast with brute force methods which are very easy to understand, and possibly are bug-free as well. But they are not elegant.
Elegance almost always brings maintainablity, extensibility, readability, and speed, but these are side-effects, not the goal.

What exactly are you meaning by elegant?

>What exactly are you meaning by elegant?
Hard to describe exactly, but it's the opposite of 'clumsy', or 'quick and dirty'.
It's code where anyone that reads it will look at it and say 'nice!' There's something intellectually satisfying about elegant code. It achieves a lot in a few lines of code.
How much of my code is actually like that? Not much. But it's still the goal. Every time I refactor my code, I'm trying it make it more elegant.

yeah .. bug free then elegant is my style too, so no shame to the customer .. right ?

It seems a bit odd that a goal which is almost universally regarded as being practically impossible for non-trival applications (Writing Bug-Free Code - currently at 27.05%) is number two on this survey.
Shoot for the sky, I suppose...
