One that you know nothing about the members of and is implemented in an unseen library source file.
>>52184109
So does that mean that no struct typedef that i create can be considered opaque, since I designed it and know exactly how it is implemented?

That is an opaque type. It's not defined in that translation unit.
You can still pass pointers to this type around, but you cannot access this type directly.

No, but I've had this
>>52184116
I suppose if your memory is real good no type you ever design would be opaque.
>>52184131

>>52184139
>you cannot access this type directly
but why?
Does it not have any members?
Or is there a special C keyword in it's header prototype declaration that prevents me from accessing it's members?
>>52184116
It means that the user shouldn't know what the fields are and how it operates internally.
They should just know that using structType_doThis and structType_doThat do what you expect them to do.

>>52184154
>but why?
Because the compiler does not know what the struct contains, so it cannot generate any offsets or whatever to access anything.
Each compilation is separate, so the library code knows what it contains, but the client code does not.
Here is an example of how opaque types are used:/* public_header.h */
struct test;
struct test *new_struct();/* lib_implementation.c */
#include "public_header.h"
struct test {
int a;
};
struct test *new_struct()
{
struct test *t = malloc(sizeof *t);
t->a = 10;
return t;
}/* client_implementation.c */
#include <public_header.h>
int main()
{
struct test *t = new_struct();
}
>>52184201

Can't back up a struct with only the space for a mere pointer to it.
I have been looking through documentation on rust's linking process, and how .rlib shit is supposed to compare to the .a and .so files I am used to on C and C++.
>>52184154
No keyword, it's just that the struct definition doesn't exist. When I make something like:struct foo;
That tells me, "there is a struct type called foo." At this point, I can make a pointer to an object of type foo. What I can't do is declare an object of type foo on the stack. Why? Because I don't know how big it is and I don't know what its members are. If you do something like:struct foo bar;
The compiler's basically going to ask "the fuck you want me to do? How big is bar supposed to be? I don't fucking know!". But if instead you do this:struct foo *bar;
The compiler's just going to assume bar is the size of a void pointer, and whatever it points to is someone else's problem. But you can't do pointer arithmetic with it, because it doesn't know what *(bar + 1) even means.
>>52184272
You don't know C, do you?
It's allocating the size of what t is pointing to.

I don't see that sort of case being uncommon. Obviously you wouldn't allocate a single float or whatever, but the effect only gets worse with arrays.
>>52184386

Holy shit.
Guy in /agdg/ is trying to argue that C structs are objects (as in OOP) because when you allocate a struct you are actually allocating a "struct shaped object", and that all "object" means is "data in memory".
Hey guys can anyone help? I'm going through A smarter way to learn Javascript and I'm stuck on this problem here:var cleanestCities = ["Cheyenne", "Sante Fe", "Tucson", "Great Falls", "Honolulu"];
var cityToCheck = prompt("What is yor city?");
var matchFound = false;
for (i = 0; i <= 4; i++); {
if (cityToCheck === cleanestCities[i]) {
matchFound = true;
alert ("it's one of the cleanest cities");
}
}
if (matchFound === false) {
alert ("it's not on the list");
}
I can't get "it's one of the cleanest cities" to print out after typing one of the cities in the array into the alert box. It just goes straight to "it's not on the list" I'm trying to utilize a flag variable, but it's not working. Any help would be appreciated. Also, anyone have any js resources they highly recommend?

One more question about opaque types.
I've noticed that many libraries will use what appear to be opaque data types for passing data between function calls, but they're not actually opaque, since you're free to put them on the stack.
regex.h does this with the regex_t type
openssl/md5.h does this with the MD5_CTX type
Should I just avoid opaque types when writing library code?

Opaque types solve a problem, which is primarily about ABI and less about encapsulation. If you don't have that problem, you don't need to use opaque types.

You don't want a semicolon on this linefor (i = 0; i <= 4; i++); {
Also if you're done with your for loop, you should always break out of it so you don't keep on unnecessarily continuing when you already have the data you want. It doesn't matter so much in a small loop like this, but it's good practise to get used to it anyway.
>>52184652
True. But for types that are in flux and COULD be changed in minor versions, opaque types are the way to go. You don't want to lock-out any changes you could have done or break the ABI just because you didn't use an opaque type.

So I'm a bit confused with the results I'm getting from SBCL and two compiled functions. I'm currently testing the performance between a recursive function and a tail-recursive function in Common Lisp, however, so far I'm getting that the recursive function is faster. Is there any particular reason for this? Here are the two functions:(defun fac (n)
(if (= n 0)
1
(* n (fac (- n 1)))))
(defun fac (n)
(if (= n 0)
1
(* n (fac (- n 1)))))

What happens if you write the tail-recursive one with a helper function instead?

C does have libraries, you know.
If I put an enum within a struct, the enum values in that struct are only accessible when that struct is an lvalue in an expression, or do they pollute the global namespace?

Okay, so, I think I've gotten a hold on how the fuck Rust's linking system works. The preferred method of handling separate compilation would appear to be with .rlib files, which contain function, module, and type information. They are imported into a file through extern crate, and exported by using #![crate_type = "lib"]. In this sense, a file is allowed to know a little bit about how it is being linked, rather than all of this information being in the command itself.
Files can be exported as assembly, object code, or llvm bytecode using the --emit option for rustc. It does not appear, however, that one can link against plain old object files as one can in C. If one wishes to use .o files made in C within Rust, one must convert them into either a static library (.a) or dynamic library (.so, .dll) and note this with an extern block with a link attribute. Functions used this way can only be used in an unsafe block.
Cargo is not necessary to produce Rust libraries or to include them within one's codebase, but it seems to be the preferred build system for doing so. There is not much "magic" behind it, however.
>>52184978
the time function is pretty standard for benchmarks AFAIK. if you suspect something's wrong with the function maybe try switching the order that you run the tests in and see if that changes anything

how many leap years are there between 1899 and 1903 then?
>>52185378
You've only been posting on here for 3 weeks, scrub.
>>52185434
That'll give an approximation, but it won't give an exact value. Consider, for example, that there are 0 leap years between 1897 and 1903 inclusive. And yet that includes 7 years. Dividing by 4.16, whether you round down or up, the result is still greater than 0.

you guys actually get jobs programming without college?
or is that just a meme
>>52185616
If you're good, yes.
The hardest part is getting your first job.
After that, your degree becomes largely meaningless.
Even with a degree, you'll still have to pass lots of retard tests because of the amount of retards with CS degrees.
>>52185616
>implying i plan on getting a job in programming
What music do you listen to while programming?
>>52185616
>>52185646
From experience...college degrees help. Like this guy says, they massively increase the likelihood that someone will trust that you're competent and decrease the number of hoops you'll have to jump through to prove that you are.
What's more, if you can get yourself into a good school (like top 10) that effect gets even better. I go to a good CS school and virtually everyone I know is getting jobs at Google, Microsoft, Facebook, Palantir, etc right out of college. It helps a ton.

Hmmm... this doesn't look so bad in Rust....fn leap_year(year: &i32) -> bool {

}
fn main() {
let count = (1776..1969).filter(leap_year).count();

Think I found your problem.
>>52185616
You can get a job, but don't expect many promotions.
Also, it's easier to find a job with a bachelor's and no experience than it is with anything less. "No degree" or "Highschool Diploma" hires generally want a few years of experience from you. Being a drop out can hurt your chances because your employer will take it as a sign that you don't have a good work ethic.

It would work just the same, no matter how manipulate the strings, as long as you don't use == to compare them since strings are compared by reference

https://www.youtube.com/watch?v=Ag1AKIl_2GM&t=3m34s
He says companies can charge for software and it can still be 'free' according to his definition, but how does he expect a company to charge for software if anyone can redistribute an exact copy, and even sell it themselves?
Is he advocating donation-ware / PWYW systems or is his philosophy just incoherent?

I really don't like the syntax for annotating type signatures in F#
Daily reminder that if your language of choice is not on this list you should probably give up and kill yourself:
- C++
- C#
- Lua
- Python
- Elixir
- Haskell
- Bash
- Clojure
- D

"Free" software is free in the sense of "free speech", not "free beer". If you're not prohibited from modifying or distributing it, then it's "free".
> but how does he expect a company to charge for software if anyone can redistribute an exact copy, and even sell it themselves?
