Situations are random

I think 'real life' situations have random conditions. Poke tongue | ;-P

It depends on which is the exceptional condition

I usually test for the abnormal way depending on the code:

some code here...
 
if(something strange happened)
{
    do something
}
 
keep working

However, if both conditions can be normal, I test first for true:

some code here...
 
if(whatever is true)
{
    do something
}
else
{
    do something else
}
 
some more code here

I have seen this code in the wild:

if flag

else if (!flag}

If the only thing I am looking for is the false condition then I don't create an empty block. I do "not" the thing. If I change my mind later I do refactor it correctly.

This would mean I should have voted for "it depends", but this scenario happens very rarely.

It's mind boggling that those kind of surveys do get created. Even more so, that I'm actually voting for this. It's just plain disturbing that I'm not the only one

Here is Chuck Norris' version:

<br />
    set expression to true; action_1; <br />
    set expression to false; action_2; <br />

i do it like this:

BOOL CALLBACK falseFn()
{
...
}

BOOL CALLBACK trueFn()
{
...
}

ConditionFn doIt[2] = {falseFn, trueFn};

doIt[testCondition]();

It depends.

I first evaluate the condition which will probably hits more. And then second most condition to hit and more and more ...

if ( probablity to hit most of the time is placed here )
;
else if (probablity to hit a little less than the first one )

And if the condiation is more than four i use to use switch statment.

The compiler will optimize an If/Then/Else in a manner that makes it impossible to accurately predict which is more efficiently executed. See Code Complete 2nd edition for lots and lots of examples of this. Additionally, since a conditional evaluation is short-circuited, the construction of the conditional itself probably has significantly more impact on efficiency.

Thus, my view is that the conditional should be coded in a manner that optimizes clarity, readability, and maintainability of the code.

Compiler optimization of the code is related to static code analysis. While probabilty to hit (most of time); which block of code; programmer can better predict.

After all MS has a tool that lets you click, drag, and not need to think about such trivalities.

Need software developed? Offering C# development all over the United States, ERL GLOBAL, Inc is the only call you will have to make.

I tend to like to code the if so that it diverts the code into a side condition and allows the flow straight through for the most common condition.
