Other peoples code

We all have our own styles of writing , how do you find other peoples styles ? I have a quirk in that my functions only EVER have one exit point , and the first thing I do in any function is to default any returned parameters. Looking at this site I seem to be in a minority of slightly less than two , so what I do must be quirky , anyone else have style quirks ? And how do you get on with other peoples quirks ? Am I the only one forever playing catch up with technology , while all the juicy opportunites keep rolling by ?

i think the best thing to do for your own coding is to ake it self documenting ergo needing little or no comments if someone can't figure out whats going on fromthe code itself then the code itself is the problem. Something which should be taken into account at the time of writing, not later on :) Readable code is something which needs to be worked on as you code :) cheers Bryce

I also like one exit point. Just seems like good coding technique. My quirk is that I use "temp" as a variable far too often i.e. temp1, temp2,... Very bad habit but I'm not as bad about it as I used to be. Later. Brad Jennings

I mostly agree with Bryce's comment below about comments (no pun intended), that code should be written in a way to be self documenting, which is achieved primarily through useful class, function, and variable names. However, I occasionally have to write some "algorithmic" code which is not obvious. My own quirk regarding comments is that I think they mostly make the code unreadable. Therefore, if the code is non-intuitive, I put comments just above the function name, and I comment important lines within the function or class. However, I still encounter companies where the rule is "don't go past 80 characters", so comments wrap (as does code!), and are placed inbetween lines of code. Argh! :mad: What is this? The days of teletype terminals? I typically place my comments way out beyond the right margin (at least 150 chars). But then, I also use screen resolutions of at least 1280x1024, and I set my text font to 8 pt. Of course, I'm probably going blind too! :rolleyes: I like the embedded XML comment capability of C#, but I find myself spending more time writing documentation than code. (Oh, that's the way it's supposed to be, isn't it). Marc Help! I'm an AI running around in someone's f*cked up universe simulator.

"Self-documenting" code is a myth. There's no such thing. I don't care how careful you are, reading comprehension and perception of almost EVERYBODY else will be all over the scale. I'm currently dealing with numerous projects where there is little/no comments in the code, and it's driving everybody working on those projects absolutely NUTS. Comment well, and comment often. Use complete sentences and spell correctly to lessen the chances of misinterpretation. Do NOT rely on external tools or the promise of external documentation. Even better, don't rely on anyone else to follow up and comment your code for you when they happen to have to look at it. As far as coding style, don't get any fancier than you need to get. Fancy usually means complex, and complex always means unmaintainable by new team members. ------- signature starts "...the staggering layers of obscenity in your statement make it a work of art on so many levels." - Jason Jystad, 10/26/2001 Please review the Legal Disclaimer in my bio. ------- signature ends

I like one exit point too, but a lot of times, that just makes the code hard to follow. Get the exceptions out of the way as early as possible, and then write the business end of the function. Otherwise, you'll have deeply nested code that is a bitch to follow. My rule is that if there's more than three levels of nesting needed to support the desire for a single exit point, it's best not to do it. ------- signature starts "...the staggering layers of obscenity in your statement make it a work of art on so many levels." - Jason Jystad, 10/26/2001 Please review the Legal Disclaimer in my bio. ------- signature ends

I used to be a style fanatic, wanting everyone to use my coding standards, but over the years I have come to realize the following to be true. Can you read the code and understand its intent? Yes, coding style is good enough. No, something has to change. There are different levels to examine here, layout/names/spacing is the minor, and logic is the major. As long as the code is understandable and the logic is correct don't stress and worry over the minor. Unless its your own code and you are not proud of how it looks! :-D

I totaly agree with John Simmons. Self documenting code is a myth. There is no way for the code to explain why you did it this way. Other than trivial functions you must explain why and what assumptions you are making. It is amazing how smart your were years ago and do not tell me you remember why you coded something last year. Or 10 years ago or 100 years ago, If the product you are supporting has a long life span it may very well be that the code behind it must be kept. So these figures are not made up!

John Simmons / outlaw programmer wrote: Get the exceptions out of the way Good point and I agree. There are allways exceptions. It bothers me when someone blindly follows absolutes that their instructors drilled into them. Even GOTO's have usage at times. I am not saying do not follow good practices.

Look at the code on this site , it is almost universal to find a return in a conditional statement . A single exit point means that return cannot be in such a segment of code. What starts off as trivial can end up growing into something painful. so I avoid things like.. if(MyVariable = true) return(); // The use of bracketted return is another quirk !

Do you follow any 'rules' when handling exceptions ? E.g dealing with them close to where they happen or appending data to them and rethrowing them ? There must be some good ideas on exception handling , but all I ever see are nuts and bolts type articles never any ones on good practices.

Objects should implement their own behaviour. This implies that methods do one thing, not 2, 3, 4. This from what I see does a lot for understanding the code, whether or not you actualjy wrote it. Also good for self-documentation even without // or /*. And also good for component code reusability.
How low can you go ?
