Unfortunately it's a lot harder to go from C++ to C than the other way around. I find C code about 100x more readable than C++ code, and when I have to write C++, I write it in a very C-style way, which is great. You can write awesome code in C++ that looks just like C code: not so the other way around.
Basically, all I really can say is, you need to get used to doing things yourself, and doing things very explicitly. No more hidden RAII bullshit.

Kek. C++ is all about doing things under the hood to "simplify" the code. References are a great example of an integral language feature that's complete shit and ruins readability.
With references in C++, when you call a function you never know whether it's grabbing a copy or the address unless you look at the function.
C++:void doShit(int &fuck)
{
*fuck = 2;
}
int main()
{
int cunt = 0;
doShit(cunt); // cunt is now 2 even though it looks like I'm passing a copy
}
vs in C:void doShit(int* fuck)
{
*fuck = 2;
}
int main()
{
int cunt = 0;
doShit(cunt); /* does not compile */
doShit(&cunt); /* now I KNOW I'm passing it the address */
}
This obviously matters when your functions are scattered across different files.

Confirmed for failed C++ programmer.
If you feel that you have to put everything in plain sight, it means that you're incapable of writing robust classes which behave properly.
C sidesteps the problem of crap programmers who can't create sound abstractions by simply not letting anyone create any abstractions, so the crap programmers never have to face up to their own worthlessness.
The downside is that non-trivial code gets bogged down in reams of boilerplate. And robust code is even worse because of the need for explicit error handling and clean-up, so most code either doesn't bother to clean up properly after errors, or all but the most common errors get "handled" with an abort().
>>
>>51624453
>/* does not compile */
It most certainly fucking does. In fact, it'll give you a warning about conversion to pointer without a cast, and then carry on.

Which is a problem for .... nobody expect C programmers who can't get it through their thick skulls that not every language is C.
C++ uses references heavily, so C++ programmers (as opposed to C programmers who know just enough C++ to whine about it on 4chan) don't take it for granted that parameters are passed by value. If you call a function, you need to know what it does (any half-decent IDE makes this easy).
And note that in C, you have exactly the same problem for pretty much anything that isn't a primitive type. If you're passing a pointer, you don't know whether it's because the function needs to modify the pointed-to value, or just because copying a pointer is cheaper than copying a struct ... unless you look at the function declaration.
>>
>>51624764
>>51624799
And don't forget the integer not being able to store the full pointer, like a system with 64-bit pointers and 32-bit ints. Actually, that's pretty common nowadays.
>>51624821
Technically, if you were just casting, and the integer had at least as much precision as the pointer, you'd be okay. Arithmetic would still be fucked.
>>
f you want it clearly passed by value or unchanged, you can explicitly copy construct or make it const
>>
>>51624851
This. Pass by reference is OK because every half-decent programmer will use a const reference or just pass by value to indicate that the function won't mutate what you pass it. And this is clearly visible just with the function prototype.

It puts the >current< value of "old" into the array at the position. When you overwrite the "old" variable you're changing the value of the >variable< but the array (located in another variable) does not change.
As I rule of thumb (I've mentioned this before on /g/): If you modify a variable "x = ... or var x = ...", you are ONLY MODIFYING THAT VARIABLE. You are not modifying any other variables, or any other objects or any elements of any lists, you are just modifying that one variable.

Rollerino
>>
>>51624764
It's defined as requiring a diagnostic (implicit conversion of a pointer to an integer is a constraint violation, 6.5.4p3).
The standard makes no distinction between warnings and errors, that's up to the compiler.
Typically, if the compiler can figure out that certain code (e.g. what it would generate if there was an explicit cast there) might be meaningful, then it will generate that code, print a warning, and carry on.
If the compiler hasn't got a clue (e.g. because you passed an integer where a structure was expected), it will print an error, compile the rest of the file (in case there are more errors or warnings for it to report), and not bother generating an object file (because there isn't anything it can generate that isn't 99.99% certain to be garbage).

Doesn't really matter when you've spent the past year working with Indian expats and hunting down hidden shit-tastic surprises they've sprinkled your code with.
I've been wondering if I've been in a coma for a while, actually. It's too weird that as soon as a subject is brought up once it's suddenly popping up everywhere I go. Also, when you haven't talked to a friend in 7 years, think "I wonder how he's doing" and bump into him in the street that week. What is even real?

I'm saying that homoiconicity isn't really necessary if you can't modify the code at runtime anyways, i.e. if the language is compiled. You could even conceivably use something like TH at runtime but it just doesn't seem right to me.

Hey /dpt/, is there anyone more insufferable than functional-fags?
When your language takes longer to write than a scripting language and still runs slower than a real compiled language like C or C++, I guess all you can do is boast about "purity" on the internet and pretend your language is superior.

I'll bite though: the only way to make a fast program in C is if you have infinite time. Without infinite time, it is possible to write python code that is significantly faster than C code. More realistically is to use a fast non-C language like lisp, ats, ocaml, lua, javascript, or D.

I have to add that trivial programs may be good representations of some aspects of a language's effectiveness.
e.g.
string reverse in C isn't extremely easy (doable in about like 8-10 lines)
string reverse in Python is pretty easy and very simple if you write out the code for it (doable in 5 lines), but there are tricks like slicing that can get it done in like 2 lines.
string reverse in Haskell is a 2 liner normally and can be made into one line if you use 'foldl', but both solutions look very cryptic if you aren't accustomed to functional programming.

I know you're trolling but FP is very powerful, you should realize that by the fact that every single popular language has elements of FP in it. Haskell may not be practical due to being "purely-functional" and "lazy-evaluated" but that doesn't discredit the rest of functional programming (type inference, lambdas, list comprehension, stateless programming in stuff like concurrency)

Of course we had functions.
FP took them and literally discarded the scaffolding that made stuff useful.
Imagine if imperative programming was an ice cream cake. I have great tools, hot knife (cmake, autotools), all these templating things. yatta yatta
now imagine, you took the frusting with your skinny arms. and were like, my frosting! then you said, "cake, cupcakes, everything has frosting in it".
you even feel empowered. you can actually kinda ball up frosting without any base, for a bit of time
then you realize, without that strong, sturdy base, you don't have the strength to bustress and scale your cake well.
also people complain that the lack of breading, ice cream, and a refridgerator with candles makes people bored.
eating icing by itself is fine. but it's just a condiment
that's why you don't rip one part of a language and try to apply it to every last thing.

I suppose you'd need to augment C with something like a Maybe type that forces you to pattern match to either get Nothing (null) or Just a (non-null) pointer.

My point is, it would be better off if a) there was a way to quantify by type that the pointer was non-null and b) if it could be null, you would be forced to check it to get the address.

Stack overflow maybe? You can try configuring your stack size higher and see if that fixes it.
I once was accidentally allocating 1024 arrays of 1024 integers instead of just 1024 integers and shit kept crashing immediately. I could not figure it out.

Well, my point was more that I've never had a null pointer cause any trouble in C, especially since they're so easy to check against (literally if(pointer)) so adding unneeded complexity seems... unnecessary.
>>
>>51626389
I wouldn't call it unneeded complexity. It lets you quantify when you're not allowed to pass in a null pointer (thus removing the "well, I should do it anyways to be safe" check, which has overhead), and forces you to do the check otherwise.
>>
>>51626372
That's probably heap corruption, which can be caused by an overflow. What's likely happened is that you haven't recompiled all .cpp files that include the header, which leads to the code thinking the structure is smaller than it is and not allocating enough memory, or something similar to that.

That was it, I hate myself so much for trusting CMake. I've been at it for the second day wondering why the fuck is this happening and I was sure that it can't be this since CMake automatically picks up which source files rely on a modified header and rebuilds as necessary but I just went with make clean && make and it clicked. Thanks anons.

I am always amused by fags who think makefiles are useful.
I just #include all my shit into one file and compile that with some flags. I've literally never had a project take longer than a second to compile on me. Incremental compilation is useless with how fast computers are today.

Not a project that I've written myself and followed good practice on. Obviously when retards abuse templates or I need to do some bullshit with boost because some asshole was feeling lazy, then yeah, those projects take minutes. But in my own codebases, where I enforce strict guidelines? Everything compiles quickly. I literally reject any pull request that has templates in it.

PHP and Ruby are web backends , not network backends, network backend is not even a term people would use except for something specific within a network application
>>
>>51627097
Don't really care enough to get into a semantic argument, but he said networked application backend. Any web app that actively communicates with a server is a "networked application".
>>
>>51627150
>Any web app that actively communicates with a server is a "networked application".
No, web applications are frameworks which are a collection of programs that usually include a server. Servers are an example of network applications. You cant confuse web frameworks with network applications, its not semantics, they are different things. If you want to talk about network applications like servers, fine, we can talk about that. But web frameworks are just something that might include a server but is not a server itself. To take node as an example, node is not a framework, and it is not a server either, it is a web app using callbacks and runs on a single thread.

I want to program an automatically generated calendar that allows users to add activities. User adds the name and the frequency (once, twice, thrice or six times a week). Each box has a checkbox for which the value is saved.
How should I approach this? I am thinking of Javascript to add the lines to the calendar but I don't know about the cookies.

Frankly, though, with the total crap documentation on Twine I pretty much already am. None of the macros from 1.0 work and none of the macros for 2.0 are written down in any reasonable fashion so I'm scripting everything outside of basic links and story layout.
