You need a custom network driver to send layer 3 packets, it's probably going to be hard with .NET. Unless you mean you're making your own dhcp-like thing in layer 4?
what's the difference between a normal functionshort texture_w(texturestruct *t)
{
short w;
SDL_QueryTexture(t->texture, NULL, NULL, (int*)&w, NULL);
return w;
}
and a defined function#define texture_w(t) ( { short w; SDL_QueryTexture(t->texture, NULL, NULL, (int*)&w, NULL); w; } )

This makes use of a gcc extension, it is not valid C.

It's fucking UDP. Why would I need a driver to do it?
>>55361674
so it wouldn't work in microsofts compiler then? I had to define strdup this way#define strdup(s) ( { char *d = malloc(strlen(s) + 1); if (d != NULL) strcpy (d,s); d; } )
because otherwise the compiler wouldn't let me use it
>>55361719
>so it wouldn't work in microsofts compiler then?
It would not work in any compiler that does not support gcc extensions.
>because otherwise the compiler wouldn't let me use it
What do you mean?
>>55361692
You're right, I got my protocols mixed up. It's for things like custom ARP packets that you need custom drivers, as your regular drivers will only let you send TCP/UDP packets. But of course as you said DHCP is sent with UDP so there's no issue. My bad.
>>55361780
>as your regular drivers will only let you send TCP/UDP packets
Wrong, every non-shit system allows for raw sockets.

Bad-tier hobbyist here. I'm working on adding a polling function to an IRC bot I manage for my channel. I can handle most of the voting mechanics fine, and I can give it a simple time limit to stop accepting votes after, but being a shit-tier programmer I can't figure out how to have it announce to the channel when the voting period has ended and announce the results.
This is roughly what I've been able to come up with:class PollVotes(object):
def __init__(self):
self.votes = []
self.stoptime = "some date/time"
def has_closed(self):
if int(time.time()) >= self.stoptime:
return True
else:
return False
poll_list = {}
#irc processing...
if got_vote_command:
if poll_list["poll_name"].has_ended():
send("The voting period has ended.")
else:
poll_list["channel_or_poll_name"].add_vote(persons_vote)
#send the tally
send("%d people have now voted!" % poll_list["channel_or_poll_name"].tally_votes())
Obviously, this will only have announce the end of the vote when someone tries to vote outside of the timeframe. Any idea where I should start with adding some sort of passive timer? This is in Python by the way.

im writing a virtual machine in C, is there any reason the stack grows downward? I'd much rather start that shit at 0x0 -> rather than <- 0xFFFF. Besides it'd be fun to overflow the stack and start writing code if it was at 0x0
>>55363051
I never put stacks in the instructionset
>>55363051
Most compilers aren't just going to let you write to 0x0
>>55363051
It's easier to process memory that grows down. You'll get used to it
>>55363074
yes they fucking are its my virtual machine i chose the spec, and the assembler
>>55360972
The only language I like is python but it's too slow
>>55363084
Yeah, I originally thought thatstatic void vm_set_u16(vm_t* vm, uint16_t addr, uint16_t val)
{
assert(addr <= 0xFFFF);
vm->m_Mem[addr] = val & 0x00FF;
assert(addr+1 <= 0xFFFF);
vm->m_Mem[addr+1] = val >> 8;
}
If you want to write memory that grows downward the regular function I wrote to write memory doesn't work. (Try subbing in 0xFFFF for addr and see where the problem arises)
You need to write the memory in an opposite direction and maintaining two different functions for that is autistic
>>55363124

A macro "function" allows for generic arguments. Not to be confused with void* pointers or anything like that.
You could have two different structs which each have x and y attributes, and you could use a macro to do something simple to those attributes.#define normalize(vector) (vector.x /= vector.length; vector.y /= vector.length)
This would define a macro that would normalize a vector. You can have different kinds of vectors, for example, one could use floats instead of ints. This means that you don't have to write the same function twice for different argument types.
Of course, if you use C++ you can just use templates instead.

Functions generally store all sorts of information on a stack during a function call, and messing with it during runtime would probably be bad for the program
>>55363574
there's literally no need for a garbage collector
there's no need to manually allocate memory
in C++ just use string or vector and you never need to use the keyword new
>>55363591
the same optimizations programmers do in high-performance games (allocating pools of memory and using their own allocators rather than malloc/free) works just as well in a garbage collected language. In most other applications, this is not necessary.
>>55363602

>>55363619
what kind of memory management are you talking about?
scope-based (RAII)? that's quite limited, and the standard C++ way of getting around it's limitations is by using smart pointers (reference counting gc) or unique pointers (linear types).

>>55363637
again, you don't need to use smart pointers because you don't need to ever free memory
you don't need to free memory because you never need to manually allocate memory
and you never need to manually allocate memory because any kind of dynamic memory allocation is handled for you when you use strings, vectors, queues, etc

What helped me a lot when I was starting out with Rust around a year ago were the compiler hints. This is one the reasons I stuck with Rust while I gave up on Haskell.

Rust occupies a niche that is only rivaled by C, C++, Java and C#. I've been programming C++ for a decade and I currently work in the security industry as a C++ programmer and Rust solves exactly the problems I have daily: writing fast, portable and secure code. C with its lack of strong abstraction an encapsulation mechanisms is strictly worse than C++. While C++ has changed immensely since 2009 the language is simply collapsing under the weight of all the legacy shit that has been piled up since 1989. Just look at the lambda function syntax. That's completely insane. This leaves Java and C# and while they are ubiquitous in many industries this is often the result from a lack of alternatives. If you want to write a large application that needs to be efficient what else can you pick? Rust has many advantages over Java. The tooling that already exists for C/C++ can trivially be extended to support Rust. The language is not only as fast as C today -- one year after 1.0 -- but it also does not depend on a GC what makes interacting with other languages and C library easy. Idiomatic Rust is memory safe and free of data races what helps with concurrent programming. Doing this in Java is pain in the ass. Last but not least the HN hipsters love it and they are the early adopters a language needs to be successful. As I said Rust has the potential. You don't need a Sun shilling your language, C++ got popular w/o.

>Just look at the lambda function syntax
lambdas should never have been added to C++
they did this to appease the functional paradigm autists and all it did was fuck the language
>>55364726
just be happy you can put them in std::function
>>55364398
Please don't ruin it for people who aren't subjecting themselves to tripfags
>>55364726
Honestly, lambdas were one of the best additions to C++. You can finally use all the stuff in <algorithms>. Nobody will write a whole class w/ operator() just to use std::accumulate.

What are some good resources to learn modern C++11/14? Last time I used C++ was back in '07, since then I moved to Perl and now Haskell.

look up "auto"
that's all you should use from 11 and 14

Is C++14 even being used in the industry? Isn't C++98 the most common standard followed?
>>55365481
c++11 is gaining traction because they finally standardized threads and other shit
industry is limited to C++98 because compiling STL for embedded systems is autistic
What's a good strategy to build a program with a particular language I only have basic understanding of?
I have an ambitious idea for a website and I don't know where to start. An online resource with common tools/software implemented onto websites would be a good deal. Anyone have any suggestions?
>>55365372
Yeah so far it is looking like I'll save a hundred lines of code or so over the c++ version I did a while back.
Kinda going blind on graphics libraries and audio though. Not quite sure what I'll end up with.
It's meant to be a quick dirty project to get the basics. I'm 100% sure things won't turn out idiomatic or proper. I mean I've only got about a couple days experience in the language so far.
I realize I'm a retarded faggot who cannot into basic programming problems, so save your breath. But can somebody please tell me what I'm doing wrong here?#include <stdio.h>
#include <cs50.h>
#include <math.h>
#define QUARTER 25
#define DIME 10

#define PENNIE 1
float GetChange();
/* Ensures the user entered a positive denomination of money */
int PennieConversion(float decimalMoney);
/* Rounds the value obtained from GetChange to the nearest hundreth, then converts
that value to an int representing the amount of pennies owed. Implemented
to ensure there was no inaccurate fuckery on the float from GetChange()'s behalf. */
int main (void)
{
int coinsGiven = 0, penniesOwed;
float desiredChange = GetChange();
penniesOwed = PennieConversion(desiredChange);

>what I'm doing wrong here?
well, for one, you use C.
>>55363341
See, you don't even understand why it looks like that.
>>55365971
Forgot to mention that I'm using a library provided by the course, but the only time I used it was in theGetFloat()call in PennieConversion.
Not sure if the terminology I used is entirely correct either, so feel free to correct me on any of that as well.

what the fuck is a dime?

about two nickels

it is a half pence times 20
>>55366041
half a quarter + 5 pennies
>>55366041
A coin worth 1/10th of a US dollar, or .10 cents.
I used an int to represent it because the clusterfuck of for loops that I wrote to poorly implement the algorithm described by the problem set is working with an int meant to represent the amount of pennies (.01 of a US dollar, lowest denomination in our currency) owed to the customer.
