Are programmers negative people
-
I was just reading through some code, looking for the cause of an undocumented feature, and it occurred to me that something like 70% of my conditional statements are in the negative. e.g. if (x != y), or while (!p). Is this the same for you guys/gals, and is it a bad thing?

Maybe this is because one is more likely to test for error conditions first. I generally write like this:
if(someErrorCondition)
{
throw new Exception("message");
}
else if (someOtherErrorCondition)
{
throw new Exception("another message");
}

i think the real question is... is the stack half empty...or half full...

For me it depends on if there is an else. If so what ever should be executed most goes in the block before the else so my conditional will be adjusted for that.

I try to use less negative conditional statements. They are 1 extra computation afterall...
When it gets down to x86 assembly language this is not the case as the processor has negation as part of the test instruction. I am not sure how .NET or java work on this respect.

Depends on the code. I prefer the first branch to be the expected one, such as:
if(FileIsOK())
{
}
else
{
}but
if(!FileIsNotOK())
{
}
else
{
}Of course I wouldn't write FileIsNotOK in the first place because it's not intuitive, but you get the idea with conditions. Normally you would expect file to be OK most of the time, so most commonly expected case should go first.

This reminds me of a joke. An optimist says the glass is half full, pessimist says glass is half empty, programmer says the glass is twice as big as it needs to be.

Heard that one before. It's a good one :)

That's just natural. In nature anything unique can be more quickly identified by what it isn't. You don't identify something unique by leaping to the right conclusion immediately... well, some try and are often wrong. Programming follows this same pattern because most conditionals are looking for an exception to an expectation of what will be a normal value because most are used to handle something unique.

Real men don't drink from a glass. They drink from a canteen, a broken bottle, a running stream, or a hubcap, all the while looking for a target of opportunity.

Hahahaha. Is that public domain, or do I credit you when I use it on my web site?

Yep. Only drink from a mug around here :rolleyes:

I don't not find that non-positive logic tests are not less complex to understand.

I see this most often when working with code written by die-hard "only one return per function" coders. Tests for NULL / invalid values, right before the huge block containing all of the code in the function. It annoys me. A lot. I'm usually quite happy to re-write them in a less negative fashion...

You're right. These facts that you've laid out totally contradict the wild ramblings that I pulled off the back of cornflakes packets.

I seem to recall a Dilbert version of that joke where he says something like "I have a redundant backup over here" and points to another half empty/full glass.
