I know. It's not that bad. It's just interesting when you see that empty statement in the for loop.
I second the smart ass approach assessment. Someone is showing off his understanding of default loop behavior, coding bugs at a high rate of speed. I love this: "if (bVariable = someothervar) { do something }" despise assignments in conditionals and that was a simple example.

while (!sourceSubFolders.atEnd());In personal code, I begin my object variable names with obj. This allows all the objects I instantiate to be easily located with autocomplete. Plus when I am scanning through my code, its easily recognized as a variable I created. I usually do not do this in shared code as this is one of those things will annoy some developers.

Yeah, I used Hungarian notation in the early days of C++ and no intellisense, etc. It's just that I'm not sure the obj prefix helped in this case (example I provided) because almost everything in that code was an object.

The original dev likely thought they were doing cool and advanced stuff with the for statement. This kind of code works, but is the reason that I chose my signature line. ;)
Just because the code works, it doesn't mean that it is good code.

I know it's kool and all and allows for compact code, but really this has been the source of so many EFFING bugs, this construct should be disallowed in any language. Curse the inventor of "C" for adding it the language.

Yes yes yes. Also scoped variables are cool but... they still end up on the stack. There is really no need to use them, apart from making the code more difficult to read and to maintain. And: kids, always initialize your variables. If you are absolutely, positively sure that the variable in question will never be read before being written on and that the data written on it are always meaningful then at least state it in a comment.

The only hungarian notation I really like is sticking a little "p" in front of a variable to indicate it's a pointer. Just makes it easier to understand what I am doing. Microsoft loves to go wonkers with it (UINT32, and yes I know that's a type), and I have seen some code (due to coding standards) look like pStrConst_Variablename.

Personally my favorite is :
LPSTR lpszName // lp = long pointer s = string z = zero (null).
// It's a long pointer to a null terminated string, of course.:rolleyes: Thos were the good old days* when there were no Internet to look that stuff up. All you had was The Petzold and windows.h. :) *Not really all that great for learning to program. :)

If the code is well written, I concur. When they are used in 300-500 lines jack-of-all-trades functions with dozens of scopes inside and badly named variables on the other hand...

while (!sourceSubFolders.atEnd());First time I saw something like thins in a C++ code base, I thought "That's clever!" It was only the second thought that I remembered how much I bloody hate maintaining such "clever" solutions. We coders tend to be attracted to logical puzzles. It takes willpower to steer away from something clever in favor of something simple. Either that or enough experience to know how much of a PITA clever code can be.

if (bVariable = someothervar)
That's a very ugly one. I had to try it in JS. It works, always runs. C# at least gives you an error "cannot implicitly convert 'int' to 'bool'
That's nothing. I had this once in JS ` if(functionName) //that's a reference, not a call! { //Do something } else { //Some other equally poor code }` It came up at pull request that as it's a function reference, it will always be true, and thus got rejected. Anyway, the bloke went mental, telling me I couldn't reject it as I hadn't run the code to see if it worked.... He started randomly rejecting my pull requests after that.

Scoped vars make so much sense! They stop shitty devs just using those variables and other functions polluting them

no, it won't always be true. Consider:
var functionName=null;
//
// ...
//
if (functionName) {
alert('true')
} else {
alert('false')
}functionName = function() {
// Some useful stuff
}if (functionName) {
alert('true')
} else {
alert('false')
}There are plenty of use cases where testing a function for existence is perfectly valid. I guess not in that particular case though.
