The only decent sepples feature is that once you declare struct you can just use it as a type instead of having to write struct everywhere.

>>61237845
references are stupid and make functions disingenious and require you to think harder for something that's already complicated by default (unless you don't give a shit about optimization)

the one thing that c could use is a secondary facility for functions (or maybe even 3), we could call them procedures to align with pascal or whatever
something that has alternative properties, like a format better than function pointers (although it would have to be more complicated) or being inlined by default (or both)
basically what i want is lambdas from c++ but not retarded.
really just to clean up having functions in structures, im sure the oop fags would rejoice over that anyways.
if i got to ask for more i'd say a backport of postfix types from go or better threading/concurrency constructs but neither are really necessary.

>>61242545
*leaks memory*

Classes, templates, STL, exceptions, lambdas, references, namespaces, move semantics, type inference, RAII.

C is shit and obsolete, unless you need other languages to interact with your code, but even then, it's possible with C++.
And no, when it comes to langauges, there is no such thing as bloat. I'd rather have multiple tools for every situation than one tool that is shit but kind of works.
Fuck C.

This thread is the reason C++ got designed in the first place, and is the same reason it turned into the nightmarish feature creep language it currently exists as.

C is good because C is simple. It was never meant to be used with 10 trillion built-in features.

>>61242103
you can use the typedef keyword in C so you don't have to declare "struct <structname>" every time you use it.
it's just not a widely enforced practice for clarity's sake

type declaration.

struct shit {};

Using the type.

shit *x = malloc(sizeof(*x));

That would make sense.
But no, dumb ctards have to declare the struct everytime they want to use. If you don't what the type does you shouldn't be using it in the first.

>>61242582
>And no, when it comes to langauges, there is no such thing as bloat.
I feel like this is generally true, but it can harm readability when you have a dozen different ways to do the same thing.
On the one hand, if you have a minimalistic language, people start inventing their own ass-backwards idioms to do basic shit. The good side to that is that you can still generally figure out what's going on in unfamiliar code since it's built out of the same small set of primitives everybody is familiar with.

The big problem with C++ is that none of its features were designed with respect to each other, it just kind of snowballed and accumulated shit. So most of the features are halfhearted and halfbaked, and constrained by backwards compatibility concerns.

>>61242626

typedef struct shit_struct { poo poo } shit;

>>61242658
Dinosaurs hate typedef structs and consider them bad style because ???.

Really the only reasons I choose C++ for big projects is because of the C++ standard library and boost.

>>61242691
I already told you. Clarity.
If the old geezers on your team don't want you to use typedef on structs, then fucking don't. A consistent codebase is more important than you wanting to skip typing "struct" or writing a macro to do it for you. That's literally all there is to that.
C can do what you want it to. Somebody not wanting you to do that is a situational problem and not the fault of the language.

>>61242680

typedef was mistake.

Generics, this is my biggest gripe with C, other than that it's good.

C has an extremely important feature that basically no other language has, and many other languages actually rely on: its simple and stable ABI.

My point is the same as above. Also, namespaces are fundamentally useless.

>You mean like global and static variables?
That's slightly different.
Here is an example. Please tell me what the last line of this C++ code will print:

int a = 10;
fn(a);
std::cout << a << std::endl;

The prototype and implementation of fn has deliberately been left out.

>>61243288
>Declarations only count when I do it!

a = 10;
fn(a);
std::cout << a << std::endl;

It's just as impossible to know what this will print.

That's not C though. Dumb fuck.

>>61243430

If fn takes a as a mutable reference, it could change the value of a to something else. This is an extremely useful language feature. Why might you want to mutate your function's arguments? Well one example would be a swap procedure. Where might this be useful? In sorting a list, of course!

>>61243483
C already has a mechanism for that, it's called pointers.

I can understand the desire for purity and clarity that explicit pointer usage satisfies but the fact is that C already has plenty of impure mechanisms.

In C a will always be 10. Dumb fuck.

int a = 10;
fnp(&a);

value of a might change in the function call.

>>61243514
>>61243443
C is incapable of changing the value outside of it's scope without a pointer, and no pointer is being taken there.
C will always print 10.

> syntactic sugar
Don't say that or the rest of the Cfags will start climbing out of the woodworks.
Just as soon as they're done handrolling their 50th boilerplate linked list.

>>61243595
You fucking know the local variables that you're working with at the moment, and don't have to look far to see how they're defined. Projects have hundreds to thousands of functions, defined all over the fucking place.
My whole point is that the C++ code is misleading as fuck (as is most C++ code) and hides a lot of important information from you.
You'll say "just look at the prototype". Sure, but are you really going to go hunting around your codebase for fucking dozens of function prototypes so you can fucking reason about the state of a couple of variables?

>>61243575
Generally in C you allocate the memory your self and call init function on it.
If you want to provide function that retuns allocated memory then you provide creation function and function to delete the object.

thing var;
thing_init(&var);
void *ptr = thing_new();
void thing_del(ptr);

Then again most people program in their own fucked up way and you can never be sure.

>>61243643
Constructors/destructors are magnitudes better than this. And it's standard.

>>61243701
Constructors and destructor are fundamentally pointless, and don't add extra power or anything of actual value.

>>61243613
>Methods
>Constructors
>Destructors
All fantastic. RAII is by far the best idiom C++ has brought to the table. Memory management without a GC and without free/delete, what could be better?
>Polymorphism by virtual methods
Meh, I don't like how C++ has two major and conflicting polymorphism mechanisms.
>Operator overloading
Dangerous, people use it for retarded shit. Streams, for example. At the same time it's indispensable if you're working with any arithmetic types that aren't primitives. Needs to be used with discretion.
>Function/method overloading
Absolutely useful, but it comes with name mangling which is the main thing that fucks the C++ ABI. I'm not sure if this is entirely a good thing, but at least I can turn it off.
>static_cast/dynamic_cast/reinterpret_cast
>User-defined contextual conversions
Generally useful, although it sucks that casting is so much more complicated than C. Especially when you have complex logic in implicit casts.
>Templates
The other fantastic feature C++ brought to the table. Along with lambdas it's the reason std::sort is twice as fast and twice as readable as qsort. Syntax sucks a bit though and there are weird, sometimes esoteric limitations. Maybe D has it better.
>Template metaprogramming
garbage and unreadable, please just use constexpr
>Type traits
Not familiar with this.
>constexpr
A small but useful thing. Doesn't cause any damage but makes life a little easier. It's nice.
>The STL
It's pretty great in general, but some stl classes are really showing their age. Too often you'll find it lacking and try Boost, but then you're bogged down with dependencies.
>Modules (future)
Desperately needed and needed soon.
>Optional parameters
See function overloading.
>Lambda expressions
Great in theory but a little awkward to use unless you're templating a lot.
>Scoped and strongly typed enums
That's all right.

Namemangling in sepples is well defined.
Virtual methods and how classes are stored / called is implementation defined and the biggest reason why sepples cannot be used easily from other languages.

>>61243761
>Namemangling in sepples is well defined.
No it's not.

>>61243752
>Namemangling in sepples is well defined.
Where's the standard definition?

>>61243752
The exact purpose of a destructor is to release resources when the object that contains them goes out of scope.

>>61243853
A destructor is just a function which frees resources or whatever.
What you're describing is something else.

>>61243889
In C++, a destructor runs whenever an object goes out of scope, just as a constructor runs whenever it enters scope.
They're not the same as open/close functions.
