Cleverness
-
There must be a reason why "Clever" begins with "C". C was designed for and by clever coders. :cool: One of the practices I least liked seeing in C programs was things like Given:
char* s
The test:if ( !s ) ...
The test:if ( s ) ...
Rather than:if ( s != NULL ) ...
are you sure !s is the same as s != NULL ?

Yeah, there was a time when I wrote 'clever' C++ code, but I got over myself.

I think we all go through that phase. I agree with Josh, writing simple code that works is smart. Being 'clever' only sets you, or your successor, up for trouble. That said, I do sometimes take a perverse pleasure in properly using the -- and ++ operators, knowing full well that a rookie will spend some extra time on a particular line. :suss:

He means if you can see a way to make 5 lines work in one line of code, a simple example is int n = myInts[index++]; that's not *terribly* clever, but as a rough off the top of my head example, incrementing the index in the next line of code makes clear that you want it to increment after the operation. I know that in my early days of STL I delighted in writing code that in hindsight was far more obscure than this, on the basis that I knew how. But, you quickly realise that readable counts for more than clever, it's part of being a team player instead of trying to show off, IMO.

Unfortunately, that sort of statement is in a lot of C and C++ code. I dislike embedded expressions that have side-effects. It makes the code unclear and difficult to debug.

This brings us back to the subject of functional programming. Without defining several intermediate, delegate type, functions, I can't see how even a small number diabolically nested functions can ever be readable without some sort of stack based source editor.

You mean like: foo.GetType().GetProperty("Bar").SetValue(foo, "fizbin", null); when foo.bar="fizbin" would have worked just fine? Marc
I don't know if that qualifies as clever, just verbose.

Clever code requires me to spend time figuring out how some pompous smart person thinks. Smart code allows me to just read it and move on. Agreed?

I touched on this in a recent blog[^], where I said how much I enjoyed a hard-core session of copy and paste coding, over spending too much time writing really clever, generalised code. I'm not going to be adding many more, if at all any, new web pages to the project, and all my copied and pasted, repetitive code is working now, where I'm sure the clever code I could have put out would still require more thorough testing.

The cleverness should be in the solution to the problem. How you execute that solution in code should be simple and elegant.

Well, I will agree mostly. I still have to hesitantly present a situation, that someone else brought up. Sometimes the non-clever way is too cpu-intensive. I have been accused of writing "clever" code, even though all I did was bring game programming techniques to sci-vis and engineering. I didn't invent anything, I sped it up by an exponent or more. Quaternions were once considered clever because it was a mathematical concept that was difficult to imagine (try imagining a 4 dimensional unit vector). But today it is normal to use for solving problems. And now people are coming to me because they somehow just discovered quaternions. :laugh: But cleverness for the sake of showing off, that programmer is no different than a pilot hotdogging. He needs to grow up. :-D

I read somewhere once, I think in a description of multi-dimensional mathematical stuff, that understanding and applying it requires one to not try and imagine real world examples, of e.g. a tesseract, but to simply accept them as abstract entities and use them.

The rule of three: "The first time you notice something that might repeat, don't generalize it. The second time the situation occurs, develop in a similar fashion -- possibly even copy/paste -- but don't generalize yet. On the third time, look to generalize the approach." -

Bah! As long as your "cleverness" is well documented, why is it bad? Maybe you can learn some new techniques or ways of thinking from someone else's cleverness. Seems to me programmers these days don't want to think, or don't have time to think. I like a good brainteaser every now and again - keeps me sharp!

CP is notorious for overvaluing "clever" things. That's probably why lame one-liner posts on the forums always get 5 star votes. Clever coding isn't a technical problem; it's a personality problem.

Ummmm - define 'clever code' - what your message says to me is that you don't believe you should have to think when reading code - I can't agree with that.

Clever code is unabashed geeky-ness. Code which is written for the sake of proving how smart one is, or how knowledgeable one is of abstruse features of a language. I certainly agree that reading code requires thought, but something which can be simple shouldn't require me to sit there and "figure it out." They don't pay us to prove how smart we are by creating little puzzles, they pay us to create working software on time.

Oh, if you want clever and terse, and if I knew about C# lambda and functional programming, I could probably whip somethin up that harkens back to the days of APL. Marc
