It's the year 2017. Use nullptr, not NULL.

Am programmer can confirm

0, null and blank. My team never fully king gets it. Same with boolean, only store false if null means something!

Love it :-)

Idk programming but I think I get it

There are 10 types of people in the world...those who understand binary and those who don't.

I'm not a programmer and i understand. Not sure why though

That resonates more than thirty minutes worth of office hours with !y programming 1 professor

It's a trap, I mean switch

So when I used to say between 0 and none, there was actually something between them.
SaxonBulkav2
For people who don't understand. When computers see 0 they only see it as a value, null tells the computer there is nothing there

oh shit!

Meanwhile, I'm trying to explain how much better this type of toilet paper dispenser is. Japan over engineers everything.

I'm not a programmer but I still understand it, does that make me smarter than all programmers?
ShowMeYourButtonhole
It means you are logical. Congrats! Coding is just a logical way of expressing statements.
DownvotesAreFun
There is many other things you need when coding. Patience, planning and dedication are all important too. E.g. I always forget semicolons.
ShowMeYourButtonhole
Now you're talking about software construction as a whole. Avoid languages with semicolons.
ShowmeOne
thank god im ....bi-polae
TeammateAssist
I don't get it.
0nceUponAMidnightDreary
While 0 and "null" are basically the same outside of logic (empty), 0 is still "something". Like an empty tp roll vs nothing at all.
mammageek
I totally couldn't even tell they were TP rolls.
kernell32
Like, 0 is you've run out of X and null is you didn't even had X to begin with?
TheSwedishCryptid
not really, 0 is a numerical value of X. Null is X doesn't have a value what so ever.

Stupid programming joke that isn't funny.

Just because you say "only programers understand" that doesn't make it funny

Zero means none of something. Null means there is no something.
GlitterInTheDarkNearTheTannhauserGate
what about undefined
Klhumnpgooier
Zero just non and o takes a full alphabet
Rowee
So an empty cup vs no cup?
RogueKitsune
Depends on language. Some, yes. Others, knowing there is no cup vs not knowing where to find a cup, trying anyway, and grabbing "something"
EvilDeadTed
Yes.
darthOnion
Memory allocated, no value assigned?
ShowMeYourButtonhole
Null is a constant. Null is null is null.
TheLordofMelons
Depends.

You are a very slow learner
FrozenTime
It's important to know the difference, but you can get by without knowing why (1+1 = 2: doesn't really matter if you don't understand why)
CaptainObviouslikesthemthicc
Thanks internet stranger.
Loftskip
This is the the worst lie anyone has ever told.
DerpMeister
It's more complicated. Imagine you try to grab the toilet paper and instead you grab a random item in your household while someone (...)
Llording
Mm, depends on the language. For C that's perfect, for Java less so. Either way you're gonna have a bad time.
DerpMeister
True. I gave lessons in C when I was working at the university.
AquaCrusher
It's true in the context of having toilet paper available for not I think?
Mephane
Dereferencing a null-pointer doesn't yield a random bit of memory. It's an instant access violation (i.e. crash).
Sveniat
what would an uninitialized toilet paper roll look like?
DerpMeister
(...) bangs against the door and yells that your not allowed to touch that.
Moghul

TheBlindFreak
And a majority of people won't understand just how perfect this analogy is.

Going by upvotes there's at least a few XD

I just finished a course using C not too long along... yeah, this is perfect. :D

There are 10 kinds of people in this world, those who understand binary and those who don't.

There are 2 kinds of people, those who can extrapolate from incomplete data.

Brilliant Android sheerly brilliant (and I know sheerly isn't really a word but it's soo win).
IFoldlyGo
There are three kinds of people. Those who can count and those who can't
GregorSamsa
I never got why this isn't saying there's 3 types of people 0, 1, 10.
LerkNJerk
Nicely done!
iouoneusername
0 is still 0 in binary.
GregorSamsa
At least I think it is
GregorSamsa
But in a list the third item is 2
iouoneusername
Yes, but that's because the first item is item index 0. It's waste of memory not to use 0 as an index.
GregorSamsa
So.... 0, 1, 10 is 3 items... if those items are people who understand binary are there not then 3 of them?

As a c++ programmer no semi colon hurts

As a programmer, using PHP hurts in general.

TurdlyShitkens
jQuery isn't even a language.
PiGuy314
That's not jQuery. It looks like PHP.
danishjuggler21
Dollar sign says PHP, but lack of semicolon excludes that. Python?
immorecreativethanmyusernameletson
Looks like php to me. Source: I develop in php
tonebacas
Not any Python that I've ever seen. I'm not even sure Python allows for variables with dollar sign in their name. Javascript, however, does.
danishjuggler21
Powershell, then? @128k what's your syntax?
TrueWhiteAfrican
I am pretty sure that it is jQuery
ILikeTheWayYourWormShits
Also known to non-javascript devs as a heaping pile of nope.
ItsJoshProbably
You are not syntactically required to punctuate a statement that immediately precedes a curly-bracket.
ItsJoshProbably
Edit: Actually, I'm full of shit. I must be confusing this with JavaScript, where it's entirely optional, but I don't neglect them anyways.
danishjuggler21
lol I recently had a debate with a coworker about JavaScript and doing away with semicolons - I'm firmly against ditching them :-p
ItsJoshProbably
That's like arguing to get rid of periods. Unless you're using Python where that is the defined syntax it's preposterous.
danishjuggler21
Really? I seem to recall getting errors for missing semicolons in PHP. I haven't done PHP in quite a while, though, so I may be mistaken.
ItsJoshProbably
I tried it out and I'm wrong. I'd never be that lazy, but I swear I've seen it done. It may be a php.ini setting.
DocVolt
That's the best way to explain it

I don't understand... Could you explain?
sandybuttcheeks
0 is an integer, null means there is no value whatsoever.
AlfredoTheMagnificent
I think 0 = empty and null = nothing.
Groose
Declaring a variable as 0 is something, it literally takes up a space of memory, null is nothing. There's nothing there to use up memory.
TheSwedishCryptid
0 = Value that's 0, aka the number. Null = nothing what so ever.
TheSwedishCryptid
It's like "Air vs Vaccum"

stavesacre
But...but...an int isn't a nullable type. Oh, ok fine, I'll allow it.
GlitterInTheDarkNearTheTannhauserGate
if it's javascript it doesn't matter
Tom40
In databases all types allow null
stavesacre
Ah, yeah, good point
Sveniat
it could be an int*? Wait no that just makes them both null...
Mephane
That's why nullptr is the better choice. int* x = nullptr is clearer than int* x = 0
Sveniat
nullptr is still 0x00000000, but you're right that nullptr should always be used over the NULL macro (as long as your compiler supports it).
Sveniat
I guess the bit on the NULL macro is microsoft compiler specific, im not as familiar with the linux c++ world.
stavesacre
ToiletPaper.Count = 0. Empty list vs uninitialized list ????
Sveniat
Yeah but an empty object is different than "0". That's probably the closest thing though
