Your point is understood and my point is that if someone is clever enough to understand that even not in a conditional statement is compared to true, should easily understand the point of this survey question which is, again, what you use.
Actually this if will probably be translated to some jumps after some cmp instructions which in fact are not compared to neither true nor false but to 1 or 0.
Also one might say that cmp is not an instruction; it's nothing more than a number in binary form or even not that but some high or low voltages waiting for being processed in next CPU cycle. Oh wait they're not waiting there just a flipflop is... The survey question isn't talking about any of these. It's what you type in your programming editor. Based on the question I believe choices are relevant and make sense.
Just my 2 cents.

You're still testing for false. It'll catch if the false condition is true, but you're testing for false with that.

x could be a count or something.

Um, what? You're still testing for a false condition. The does not equal part is your false test. The value of X is really irrelevant in the scope of your point.

always check for true first is the best way to code (example)
if true then (do something)
if false then( do something else)
has been my way of coding in that order
so really the question is misleading.

Byte Magazine (semi-lost and lamented) once carried an article by John McCarthy (sic?) on Logic Gem. He showed how the production of if then elses could be done with a logic table and speed coding and reduce errors. Logic Gem is still available. I wouldn't code complex flow of control without it. Generates code in readable languages and c varieties too.
I have no commercial or personal relationship with Logic Gem, Byte or John McCarthy. And, my opinions are my personal ones.

Depending on the problem at hand, I almost always opt for switch..case over multiple if..else statements. General rule of thumb in my style of coding is that if there's 3 or more conditions to check for then switch...case is the way to go. Makes code much easier to read as well.

Logic Gem even has an option to generate case structures from the logic table. Inclusion of the term Gem in its name is no exaggeration.

If only all languages had CASE statements... *sigh*

Depends a lot upon the language's implementation of switch().
If the condition depends upon a string comparison, than you can use the switch with C# but not with C or C++;
Thereupon, I become most perplexed: do I change this particular style with language?
Simplcity vs. consistancy.
Further purplexation: does it matter - for how often would I convert interconvert C++ and C# ?
Now see what you've done to me. I'm afraid to go back to my code and check to see what I've done.

Personally I don't think it matters. Chances are when whatever it is you're working on needs C or C++ then you will probably find all your old nuances from the language fill your code, same as it is when you write in C#.
I see programming as an expression in itself, and much like spoken languages each language has its own idiosyncrasies. Does that mean then, that coding style is a dialect of the language?

The W stands for Honesty.

Well - That must be why he spent so much time sitting Oval Office
(At least when he wasn't on vacation).
Then, too, I saw his last press conference - and I'm not so sure I believe the standing part, either.*
We really enter into a very philosophical domain:
Can an idiot (or even a mere moron) be deemed honest or dishonest?
* He considers his biggest error in Iraq to be the 'Mission Accomplished' sign.
Clearly, he's either an idiot . . . or a liar.

Nearing soapbox territory are we and I'm waiting to get blasted by an unhappy republican.
I have a friend who has put forward the notion that he is not an idiot but rather "acting the country fella" to mask a true agenda. I disagree and am more inclined to believe in idiocy.
Balboos wrote: Can an idiot (or even a mere moron) be deemed honest or dishonest?
Hmmm... interesting question. I would imagine that one would first need to establish if said moron is mentally capable of understanding what the terms honest and dishonest mean. If such capacity is there then the branding is fair.
Let's just hope the one coming in isn't as bad as the one going out. Frankly, I don't think you could get much worse. Wasn't the last democrat president Bill Clinton?

As the poll suggests, there is a philosophy behind the simple task of using conditionals.
For one, I try to avoid too many if(a == null) return; statements, since it makes the code less readable.
I am wondering what others opinion is on this.

Nah, I mean constructions like this:
foreach(Item a in collection)
{
if(a.b == null)
break;
if(a.b is SomeOtherClass) {
if(a.b.c != "Something")
return;
}
}
A complex foreach loop with preferrably more than 20 lines of code inside of it. Aside from the fact that I would like to extract some methods from inside the loop. I think its quite nasty to see that many returns and breaks.
I totally understand the fact that people use if(a == null) return; statements at the start of the method. It's actually quite easy to see what the method expects. I do like theif(a == null) throw new ArgumentNullException("a"); construction better.

If do similar except I invert the condition
if(myObject != null)
{
}
else
{
}
That way I have logic focused at the top and null handling below it.
Either way works. Just prefer this one

If the negative outcome is shorter, I put it at the top.
if(checkIfSomethingIsWrongHere)
{
return null;
}
else
{
}
If the error routine is in the same method and rather long, put it second
if(haveWeSucceeded)
{
}
else
{
}
