For me, the Problem here is not the if, but the arcane magic in those numbers. Why exactly 13? And what makes 20 different from 21?
Though I speak with the tongues of men and of angels, and have not money, I am become as a sounding brass, or a tinkling cymbal.

Well - how would that (or the use of the inverse logic proposed by leppie make things any clearer?

Indeed, one if is better. Also revert logic and set ++i; at the end of the code. This gives another performance boost.
codito ergo sum
This is a piece of code that I got to see from a project that has come to us for porting it to .NET. Nobody from our company is "technically challenged" enough to write something like that. :)

That isn't our company code! Just see how many WTFs are there apparently within a few lines of code.

This is a s/w that deals with a list of human interface devices. There are two APIs, namely
getPortCount(DWORD devID)andgetNextPort(DWORD devID)(from the docs that we got), that would assist you in the very range check that you're talking about. Clearly, the dumbass guy who wrote it did not bother to open the docs. That solved, there's a new WTF. The next issue listed is that the app crashes on 64 bit machines. I can read it in the docs that these numbers, which were hard coded in the original code WILL vary on a 64 bit machine! :rolleyes:

I don't think this is correct if you or 12 with 19you get 31 all of them give you 63 this means that (i & (12|19|26|33)) == (i & (63)) and that will be true for 63 and for 177 and for 191 and so on ... The following should be correct
if(!( i==12 || i==29 || i==26 || i==33)) ++i;codito ergo sum
Yeah you right, im kinda brain dead at the moment :p

Out of context it is impossible to guess, but over a limited range the code (rather clumsily) does

I am reminded of Abhimanyu's story (http://en.wikipedia.org/wiki/Abhimanyu[^]) This guy knew one part of story of incrementing the variable but not the other part of decrementing it. :-D

I've sussed it. This is a candidate for when the guy is optimising the code. Imagine the scene. A manager is whining about how long the code takes to run, and this guy says that he'll optimize the code and he spends 10 seconds removing the code and the next 20 days surfing dodgy sites. 20 days later he runs the application and it runs faster without the useless code. Result - he gets a glowing review and a hefty pay rise for removing this steaming pile of crap (hey a new acronym, SPOC). Obviously this guy doesn't use CodeProject because, God forbid, no developer on this site would ever produce code as awful as this.;P
Deja View - the feeling that you've seen this post before.

I would use an "else if" to make it clear. Did the guy not knowing about enums or switch. or: if( i !=13 && ....) i++; I wont see other source code like this... it is often only the top of an icecube

Well, what would you expect something from a guy who has hardcoded the port numbers :rolleyes:

You can't just go about it like that. Those numbers will vary from device to device (the app deals with more than one HID). Most importantly, these values will change for all the devices on a 64 bit computer!
