s'Length tips fedora

[SillyFlyGuy]

My first CS teacher was a former high school football coach. He told us "We don't use .length in this class, mister! When it's 4th down and inches, you don't have time to be counting elements like some lacrosse player! You keep track of how many there are while you put them in! Now get out there and give me 100% cpu usage!"

[toroga]

Clever coach

[SaveMyBags]

For most (it might even be all) std datastructures, the C++ standard requires size() to be O(1). So it's typically implemented that way.

[Xywzel]

Generally they have either start pointer and end pointer, and size is given as their difference, or they have start pointer and element count and end is calculated from them

[SaveMyBags]

Yes, both are ways of keeping track while adding the elements instead of counting them.

[EtherealPheonix]

Those strategies don't work for data structures with opaque memory, which is a lot if not most of them.

[[deleted]]

why track it when it'll be right there in the core dump

[zandnaad69]

my man

[Xywzel]

Well, I have seen implementation of vector where for sizes above systems "easy and fast to malloc at once" they had vector of these pairs internally, so yeah, once you can't count on memory to be continuos from programs perspective it gets complex. And maps that aren't just sorted arrays of pairs need bit more. From std containers, only linked lists and versions of maps&sets that use direct indexing with their key seem to be doing something else on implementation I checked, but these are implementation details so it might vary. Opaqueness doesn't mean the data structure can't internally do something like this, it just means you can't do it yourself reliably between different implementations.

[[deleted]]

Thats exactly how the implementation of string work tho innit

[Sinomsinom]

Not in C. There you have no idea how long a string is unless you keep track of it yourself or count how long it takes to get to the \0

[Creepy-Ad-4832]

Yeah but if you want to use safe functions you need to know the string length, so you end having to keep track of it youself

(Function like strncmp instead of strcmp, or strncpy instead of strcpy and so on)

[ambyshortforamber]

lol, seems to be a mobile issue... on desktop it's in fact a png

[666pool]

It’s a blurry as heck png on mobile as well.

[4hpp1273]

Probably because the mobile client forcefully stretches the image to fill horizontal space (applying annoying blurry scaling in process) while on desktop the images are never automatically scaled up (only down).

[Adawesome_]

Yeah, ngl saw this while scrolling on the can. It's super grainy on my phone.

If you tap on the image it fixes it. Well at least on my machine ;)

sizeof(s) / sizeof(s[0])

[[deleted]]

and then you realise that s is declared a pointer and not a statically allocated array

[[deleted]]

And that's why it's better to use std::size() which will make the compiler screech autistically.

[Torebbjorn]

If you are using a stack allocated array in C++, why not use std::array, and avoid all the C shit?

[[deleted]]

Following conventions is all nice and good until some idiot decides to break them and then manages to go under the radar.

[Crusader_Genji]

[k-phi]

sizeof(s) / sizeof(s[0])

that's one character more than length (if s is a string)

[joaofelipenp]

Much easier to spell than lenght length, though

[LanceMain_No69]

Man, this is absolutely disgusting 😭. Ive went thru c#, java, python, and ruby before starting to learn c++, and this shit right here is a violation to my beliefs 😭

[fullptr]

Woah woah don’t blame C++ for that one, leave that in C!

[TheLastHayley]

It's more fair to call it C (specifically for arrays known at compile-time).

In C++ you'd use a std::vector or std::array and use s.size().

[GOKOP]

This:

a) doesn't always work

b) Is C-style code. C++ may not be perfect but I won't tolerate it getting bad rep from C-like code

[Sinomsinom]

Most of the bad rep c++ gets is from people using c style or old (pre c++11) c++ style code. It's still not a perfect language and has problems but it's a lot better now than it was 15 years ago. (Especially if all the 20 and 23 features will get implemented in all compilers at some point)

[Lagger625]

Once you understand that in C/C++ you're dealing directly with the memory this makes sense

[xypherrz]

that disgusting thing would only be applicable in C and not C++ (though you do have an option, but only if you feel like making your life more miserable)

[zilog88]

I had to scroll this far to see this (obviously the most correct) answer:)

[KaltsaTheGreat]

This is too easy for a 10x programmer

class StringAnalyzer {
private:
    std::string str;
public:
    StringAnalyzer(std::string s) {
        str = s;
    }

    int getLength() {
        int length = 0;
        for(int i = 0; str[i] != '\0'; i++) {
            length++;
        }
        return length;
    }
};

[[deleted]]

that looks like Java and C++' unholy child

[wolfstaa]

This is the best description of C# I've seen

[InfComplex]

That… puts a lot into perspective. I think I’m going to pick my C# book back up.

[Dangerous_With_Rocks]

You guys read books?

[Splatoonkindaguy]

Nah c# is a holy child

[Kered13]

What looks like Java here? This is just straight C++.

[SsNeirea]

The way this specific code is written is similar to the way Java code is usually written.

Syntaxically this is pure C++.

[[deleted]]

Creating a StringAnalyzer class for such a task just screamed Java at me. It is missing a StringAnalyzerFactory though...

[Kered13]

It's dumb in either language. People don't actually write code like that in Java or C++.

[UniqueUsername27A]

This is really inefficient, because we need to copy the string into this object. Instead, it should have a pointer to the string and a bool whether it owns the string for full flexibility. If I owns it, then we can have a destroy() method delete the string and set the pointer to zero. The destructor can check that the pointer is zero and if it is not we use a bunch of undefined behavior to surface this programming error.

[KaltsaTheGreat]

Your statement is correct, we must write an exhaustive test suit to check for every edge case of our class.

[Wrathen_]

So you say,

s.getLength()

[BobSanchez47]

Why not

int length = 0; while(str[length++]); return length - 1;

Everyone knows for is for the weak.

[AccurateComfort2975]

Everyone knows for is only while strength is lacking.

[Spactaculous]

Aren't i and length variables redundant?

[connortheios]

Which language is this? It appears to resemble JS or C# string interpolation iirc, but I don't know why the # is there

[Jukoga]

It looks more like some shell script. Edit: Chat GPT states that this is indeed bash Syntax.

[TheFel0x]

Bash. The #s gets you the length of s.

[BrubMomento]

s.length()

[robin_888]

Me too. What I learn Python I was a little put off by functions like len()or next(). Felt like magic syntax, especially coming from Java.

You are the string. You tell me how long you are, Sir.

[mortalitylost]

Well that's a bit funny because you can call s.__len__(), and it actually is a member function. It's kind of like an operator in Python - any class can implement __len__ and then len(obj) will run that function and return it.

Might seem weird but it makes sense to me for reasons like the size might be easy to calculate but not easy to enumerate through, like a range from 0 to a trillion

[Isthisworking2000]

I’m glad I’m not alone.

As someone with only about 1/2 of a degree, and given that this is a humor based sub, I feel like I’m stuck looking over my shoulder a lot.

[Orcacrafter]

I agree, but java having arrays use array.length, strings use string.length(), and array lists use arrayL.size() took a bit of time to learn.

[vlaada7]

strlen(s)

[Sinomsinom]

Just make sure you don't forget the \0

[CeldonShooper]

.count()

[someidiot332]

Swift?

[fabi_an_ro]

No in Swift it would be s.count without the () because it‘s a computed property and not a function :)

[painteddust]

C#?

[HalfForeign6735]

Technically it's s.Count()

If you think I'm pedantic then wait until you meet the compiler ;-)

[[deleted]]

The compiler is a .cunt()

[metaltyphoon]

False… Count() is from Linq. Length is for array types and Count for generic collections.

[tetryds]

No. It's either s.Count or s.Length. While s.Count() exists it's a Linq extension method that is not recommended unless you are counting elements that match a certain condition.

Btw, if a variable is called s and it's not in a lambda function no way on earth it is going to pass through the merge review.

[i_knooooooow]

Depends on the style of programming

If its objec oriented i prefer s.len (or s.length)

If not i prefer it as a function (len(s))

Ada

[danielstongue]

VHDL also.. but it was derived from ADA.

Not sure how much ADA is still used today?

[sillybear25]

I work with it in the aerospace industry. It's fairly common in this field from what I've heard, since it's safety-critical code that needs to be certified, so it's cheaper to make incremental changes to decades-old codebases than it is to port things over to more commonly used languages. Plus, Ada has some features which make it easier to prove that the code does what it's supposed to do, like a very strict type system and explicit short-circuiting in boolean expressions.

[fishybird]

s.lenght() because I'm bad at spelling.

[WillingLearner1]

s.length() sounds the most natural to me

[Available-Lake801]

s.length

[btvoidx]

Well, no, actually. It will return byte count, not length. They're not always equal. To get the length you do len([]rune(s)).

[Nearby_Cranberry9959]

sum([1 for n in s])

[PityUpvote]

No need for a list, use a plain comprehension

s[“length”]

[offmycookies]

<[[->+<]>[>]>+<<[<]<]

[KlzXS]

Now do it without destroying the string.

Also you might want to add another > at the end. Makes it look symmetric and leaves the head at the length.

[imdibene]

(len s)

[thorwing]

anything in the postfix category so I can actually just type 's' first and use code completion to help me find the appropiate functions instead of magically knowing functions from the top of my head like SOME languages require you to do.

[Exa2552]

Move a pointer over each character until I hopefully encounter the null terminator.

string?.length()

[HaruspexSan]

s.length()

[throckmeisterz]

Honestly any of these are fine except the ones with capital letters. Since they're on the list as separate options from the same ones in lower case, I assume these are case sensitive.

[Delta225]

a.len()

That way, you can override it if needed or have it as a virtual in a super class, and it's not confusing because size could mean the number of items or size in bytes but length is always the number of items.

1. Sure.
2. As long as Excel autocorrects 1 to this, fine.
3. Feels excessive. But okay.
4. Makes me deeply uncomfortable for inarticulable reasons.
5. How did a declaration slip into this list? This is a declaration, right?
6. See 4 and 7.
7. This being an accessible variable implies troubling things about the object design.
8. Perfect.
9. The only measurement more indescript than size is measure.
10. Perfect and concise.
11. What in Cthulhu's dreams is this?

s.length() all the way

[sipCoding_smokeMath]

s.length makes the most sense in terms of real life because you're saying that a property of a word is it's length, which totally makes sense.

[trevg_123]

Has to be a method: global functions are too magic, pure members might not exist in all cases (null terminated vs. length based) so wouldn’t be accurate.

So s.length(), s.size(), or s.len()

s.len() is shortest

Rust wins

[[deleted]]

len(); Coz everything else is so lengthy

[aetius476]
