Cleverness

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

Back in the old days of game programming you had to do all kinds of clever little tricks to speed up your game. Bit shifting instead of multiplication for instance. For the 386/486 and many others the bit shifting operation was quicker than multiplication, but you can only do that in certain scenarios.

I remember those tricks, and they still work well from time to time. ---modified Though it is tough to beat an optimizing compiler these days.

Sometimes "clever" code doesn't impress me one bit.

True. I just think of the cleverness for the sake of being a hot-shot smarty-pants.

I abhor reading code which is intentionally clever. Clever code which functions properly is garbage. If you're smart enough to write clever code which works, stop being a jerk and write smart code which works. Please. 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 was never clever enough to write clever code. Unless you mean doing things like bit shifts because at times they were faster than basic arithmetic on some platforms. Now days the c/c++ compilers are pretty good so I haven't found the need to do it too often.

Absolutely... I was agreeing with you on that one!!

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

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!

I tell myself that every time i start a new project. But i never listen. And then i have to go back and clean up the mess i made of things, cussing at myself the whole time. It's easier when other people do it. I still cuss at them while fixing things, but they don't have to stick around to hear it. ;)

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* sThe test:if ( !s ) ...The test:if ( s ) ...Rather than:if ( s != NULL ) ... -

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.

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.

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.
