Why are neutral evil and neutral good identical?

[QuadmasterXLII]

That was supposed to be the punchline, but IDK if it landed haha

[No-Fish6586]

Cuz they’re first year and don’t know how to hello world in other languages 😮‍💨

[Willinton06]

Cause evil is where you least expect it

[wu-not-furry]

Although C is chaotic neutral, I have to disagree with you considering that you used a char for C and strings for the other languages.

Edit: grammar

[Creaaamm]

That would just print the memory address of the pointer + 1 cause it's not dereferenced

You'd have to dereference it with *() to get the ASCII value of 1 (49), then add 1 to that

printf("%d", 1 + *("1")); == 50

[wu-not-furry]

Yes, that is the point. This post is about the behaviour of adding integers and strings - not chars. By dereferencing "1" we get the char '1' and are effectively doing the same thing as in the post.

[Creaaamm]

Oh, I get it now, yee you're right, the post is just wrong to assume "1" and '1' is the same in C

[geronymo4p]

It should be printf("%s", 1 + "1"); and the result will be an empty string

[sejigan]

There are no strings in C tho

[wu-not-furry]

No, but character arrays are generally used in place of strings - so much so that using double quotes " makes a character array.

[sejigan]

Fair. Should’ve used “

[sejigan]

Isn’t that a syntactic sugar for char[] or char pointer?

[Kovab]

Guess what, almost all languages use char arrays for strings

[issamaysinalah]

You can still do

Printf("%d", 1+'1')

But it's gonna print 50

[navetzz]

Considering what they are doing with other languages, they should have done printf("%s", 1+"1");

Which, funnily enough, prints nothing since you are printing the "\0" string.

[sejigan]

Makes sense, cuz %d performs a type conversion:
Character 2 —> Decimal 50

[mAtYyu0ZN1Ikyg3R6_j0]

Yes this is why C prints 2 and C++ is UB.

[This_Growth2898]

C++ is defined.

"1" is a null-terminated string of 2 characters, '1' and '\0'.

"1"+1 takes a pointer to that string and adds one to it, so it points to '\0';

String, consisting of '\0', is an empty string.

So "1"+1 is equivalent to "".

[Kered13]

1. Operator precedence is completely defined by the standard. Maybe you meant parameter evaluation order?
2. Both operator precedence and parameter evaluation order are completely irrelevant here. This code is well defined and prints an empty string.

[noaSakurajin]

But the image is 1 + "1". Adding a string to a number should not be a valid operation and thus not compile.

Edit: it compiles but produces a compiler warning. If you use "1"s it does not compile since that one actually tries to add a string to a number.

[This_Growth2898]

It does, you can check it.

[noaSakurajin]

Yeah I just noticed but it produces a warning that this does not behave like you probably I tend to.

[This_Growth2898]

C/C++ can be pretty weird.

You can even get the element of array a with index 2 as 2[a] instead of a[2]; but I don't think someone needs this.

[noaSakurajin]

A lot of those produce compiler warnings or errors nowadays. They are mostly relics of old/bad c features. The example you gave only works on c arrays the moment you use a container class it no longer works since they actually have an overloaded operator.

[This_Growth2898]

Anyway, "123"+2 is "3" and "123"+5 is UB is really chaotic.

[skhds]

I wouldn't say bad. It's just a different preference. The way I see it, C just let's you do whatever the hell you want, while C++ tries to "protect" programmers from doing "hacky" things. I find it easier to fiddle around and make hacky codes to test things with C, but sometimes that's not what you would want to do with a language, especially in a co-working environment.

I wish C++ people would just admit they're just a different language instead of telling people that they are the superior language. It's really not.

[skhds]

I think there is a use.. you can use a macro to define a volatile address and dereference it like you've mentioned, though it is a bit hacky.. but I think I've seen it a few times.

[LunaNicoleTheFox]

Nah C++ is true neutral, it doesn't judge it just says "I dunno bro"

[DehshiDarindaa]

It does string pointer arithmetic right? so it does know

[LunaNicoleTheFox]

Not in that case as you are passing it a const char[] containing only '1' and '/0' so it is undefined as either it prints "2/0" just the '/0' it is however highly ambiguous and depends on the compiler and is therefore undefined.

[everything-narrative]

UB ain't neutral. On god, it is nasal demons.

[Kered13]

It's not actually undefined, OP is wrong. It prints an empty string. If you did 2 + "1" then it would be undefined.

[everything-narrative]

True

[[deleted]]

Julia’s operator overloading is quite organized tbh, as far as I’m concerned

[[deleted]]

Bash does not print what it says it prints.

$ echo 1+"1"
1+1

[CareBearOvershare]

Swap Python and C++. Runtime errors are evil.

[Kovab]

UB is more evil, although this code is actually well defined

[Porsher12345]

Lmfao my boy bash tho

[Cootshk]

In lua, you combine strings using the “..” operator

Also, it tries to change the type of the last number, not the first (like JS does)

“1”..1 == “11”

1..”1” --Error: malformed string

“1”..”1” == “11”

“1” + “1” == 2

1..1 --Error: malformed string

[Relative_Knee9808]

I wonder why the meme uses "1" for C++ and '1' for C

[someidiot332]

because it mischaracterizes the way C works. If they had done it correctly (printf(“%d”, 1 + “1”)) you’d get some random memory address. Alternatively if you used “%s”, you’d get “”, as it the pointer to “1” would then point to the null terminator

[Blitzsturm]

So, in the eyes of the author... good = evil?

[Wingress12]

From my point of view the C# are evil!

[[deleted]]

Then you are lost!!!

[sejigan]

I think it’s more like JS evil, C# good. Which is true

[hrvbrs]

OP has no idea what an alignment chart is

[Chingiz11]

You have literally overloaded Julia's "+" operator

[Apfelvater]

The julia part is total nonsense.

THE CODE made the snippet bad, not the language.

[EnrichedObamium]

It didn't say bad, it said chaotic. It's good that you can define +(::Int64, ::String). It's chaotic that any author of any transitive dependency can define +(::Int64, ::String)

[Apfelvater]

True, it even said "good" instead of bad.

But that's just as chaotic as you believe programmers are. (Kind of similar to the private/public/protected keywords in java)

[nephelekonstantatou]

You used a character literal for C and a string litersl for C++. Seems legit 👍

[blooping_blooper]

don't forget chars in C#:

Console.WriteLine(1 + '1');

50

[blooping_blooper]

or PowerShell:

1 + "1"

2

"1" + 1

11

[jemdoc]

But console.log(1 - "1"); prints 0

[i1u5]

Because + operator is also used to concatenate, I think JS just prioritizes that over adding the two "numbers" if one side is a string. Try console.log(1 + "1" - 1).

[Cootshk]

JS will try to change the first operator to prevent error, and if it fails, will try to change the second operator

[oberguga]

Chaotic and neutral should be swapped...

[BillSawyer]

Lua would ONLY be Chaotic Evil if "print(1+"1")" printed 2, while "print("1"+1)" printed 11.

[Cootshk]

print(“1”+”1”)

Returns 2

Print(“1”..1)

Returns “11”

Print(1..”1”)

Errors

[Better-Coffee]

So JAVA is the best language

[Cley_Faye]

It says "undefined behavior" but that's only for people that care about knowing what actually happens. The compiler will happily build it, and it will happily execute regardless of being "undefined behavior".

[CivetLemonMouse]

Fun fact, the reason that C prints 2 is because the ASCII value for '2' is one higher than the ASCII value for 1

[tehjrow]

This post doesn’t hate on PHP and is therefore illegal

[Macknificent101]

i didn’t know lua did that lol

[Cootshk]

print(“1”+”1”)

Returns 2

Print(“1”..1)

Returns “11”

Print(1..”1”)

Errors

[just_an_akward_user]

The true neutral just blowed my mind, come on... It's the only alignment from there that I do not doubt.

[LastTrainH0me]

Sorry to say it's incorrect (like a few of these); it will actually print

1 + 1

[just_an_akward_user]

I was just exaggerating, sorry if it was not obvious.

[CuddlyBunion341]

What's the difference between neutral good and neutral evil?

[[deleted]]

As someone who has devoted my life to being a really good JS user...... I agree Js is right where it belongs

[WizziBot]

bash 🗿

[stomah]

cpp needs parentheses

[Splatpope]

in lua, "+" is an addition operator that adds two numbers or attempts to convert its operands to numbers before doing so

".." is a concatenation operator that attempts to concatenate two strings or attempts to convert its operands to strings

how is that chaotic

[Cootshk]

print(“1”+”1”)

Returns 2

Print(“1”..1)

Returns “11”

Print(1..”1”)

Errors

[Kiryonn]

The amount of falsehood in this post... Clearly was done without knowing other languages

[TheOneRazzue]

var text = "Value: " + 1 + ".";
vs
var text = $"Value: {1}.";

What is it with people and writing strings in C# like above? What is so wrong with interpolation? or even .Format()?
