I made my first program in C++ yesterday. It's a simple gas calculator. Here is code.#include <iostream>

using namespace std;
int main()
{
//vars
double mpg, gallons, distance, totalCost, pricePerGallon;
//Output
cout << "Enter MPG of Car." << endl;
//Input
cin >> mpg;
cout << "Enter Distance in Miles" << endl;
cin >> distance;
cout << "Enter the Cost of Gasoline at the Current Time" << endl;
cin >> pricePerGallon;
//Arithmetic
gallons = distance/mpg;
totalCost = gallons * pricePerGallon;
//FinalOutPut
cout << "The total cost of your trip is:"<<fixed<< setprecision(2) << totalCost << endl;
return 0;

Is there a better cleaner way to set up the sprites in setupsprites:#define MAX 15

}
for (unsigned char k = 0; k <= 5; k++) {
init_sprite (&sprite[k+10], 0+(k*8), 22, 8, 6, ayy);

I'm trying to write an irc bot with unix sockets, but I suck at parsing.
In the function below I expect that, upon finding a a new line (crlf), I copy it to an array of lines, null-terminate it, then do what I want with it (check for commands, print it, etc).
If I do not do this, then strncmp will inevitably miss due to the fact that a command could be truncated between recv() calls with neither call actually receiving the complete command.
int loop(int sfd)
{
int k = 0;
char buf[513], (*message)[513] = malloc(513 * sizeof(char*));
const char *pass = "PASS password\r\n";
const char *nick = "NICK bot\r\n";
const char *user = "USER bot 0 0 :bot\r\n";
send(sfd, pass, strlen(pass), 0);
send(sfd, nick, strlen(nick), 0);
send(sfd, user, strlen(user), 0);
int len = recv(sfd, buf, 512, 0); /* I will check return value after I get it working :P */
for (int i = 0; len != 0; ++i)
{
for (int j = 0; j < 512; ++j)
{
if (buf[j] == '\r' && buf[j + 1] == '\n')
{
strncpy(message[k], buf, j + 1);
message[k][j + 2] = '\0';
printf("%s\n", message[k]);
++k;
if (k == 513)
message = realloc(message, sizeof(message) + 513 * sizeof(char));
}
}
len = recv(sfd, buf, 512, 0);
}
free(message);
return 0;

Holy shit, you have no idea what you're doing.

>>54697422
Most people I know have both, at least most of the people I go to school with will be finishing dual majors in math and CS. Most of the time a CS major can pick up a Math major for only a bit more work due to some overlap in major requirements, really depends on the school of course.
>>54697454
Jobs have higher wages in general.
>>54697474
Majors are meaningless. That's why the business degree exists. Companies don't care what your degree is because it won't matter: they just want that slip of paper that says
>I'm slightly above the shit they push through high school
>>54697471
Oh man I wish this was true where I'm at then I'd get a CS degree too. I'm not even getting a minor because I refuse to take the babby's versions of courses I've already taken: discrete math I & II.
>>54697387
All the function does is go through 15 sprite initiations. init_sprite (&sprite[i], xPos, yPos, length, height, bitmap); Said functions are from a specific library and the function currently works as intended.unsigned char ayy[] = { 0b10000001,
0b01000010,
0b01111110,
0b11011011,
0b10000001,
0b10000001};
On the magic numbers side, that is what I wanted to avoid. j*8 is bitmap width j+5 is trying to make sure that it uses the next sprite in sequence.
>>54697400
>int len = recv(sfd, buf, 512, 0);
recv isn't going to null terminate the buffer for you. Also, the proper return type is ssize_t.ssize_t len = recv(sfd, buf, 512, 0);
buf[len] = '\0';

So you be tellin' me
If I was a history major
but my resume said I was proficient in x number of languages or have expertise in others
or have projects that are somewhat remarkable
Then your major won't matter that much if at all?
>>54697546
Essentially yeah. If you got some facts to back that up it wouldn't matter. I know a few HR type people and they don't really care about what is written on the degree.
I think I should probably say that there is a potential this doesn't apply to the entire US though. SE Texas reporting.

Okay, so you don't want to shoot yourself. If you fuck up, you might just end up a vegetable. I would suggest taping the exhaust of your car to one of your windows and build up CO2 on the inside.

I want it to work the same on any OS: Windows should work as well as Linux. Without any Cygwin or whatever I need to get a basic sane shell going on Windows.
There are other reasons, and I'd rather write something myself since I've been inactive in programming for quite some time.
>>54697757
I use putty for SSH in windows. It's comfier and not as hacky as cygwin.
>have been in a rut the past few weeks and can't bring myself to work on any of my projects

>>54697774
It's a client, though. If I were to use SSH in my situation I'd do the reverse, which is why I mentioned Cygwin.
>>54697756
No I mean about the code.
I read up pretty well on how to do this but I've never encountered any guidance whatsoever when it comes to parsing the data.
Do people just improvise in that regard or is there a common idiomatic way to do it?
Because if there is an idiom then I've never been able to find it.
But if there really is no standard way to do this, then I'm just retarded compared to everybody else.
>>54697806
Well, from what I've heard, when people write bots, they use languages other than C for them, just because it allows them to define the behavior easily. Someone suggested perl, I don't know how much better it is, but I wouldn't use it.
>>54697823
I've heard that something like Erlang/Elixir would be good for this.
>>54697839

>recv isn't going to null terminate the buffer for you
Oh I know, I don't need it to at the moment.
>crlf - buf
Does this even work?
What does it do?
I tried it before but it just instantly segfaulted.
>>54697936
It segfaulted because "\r\n" is some windows shit. He's using it as a way to find the end of a line, which isn't "\r\n" in real OS's.
>>54697990
>>54697936
Oh nevermind I'm an idiot. You are the one writing some windows shit, so I guess \r\n would be sufficient.
>>54697936
>I tried it before but it just instantly segfaulted.
I didn't test it, so I don't know if it's exactly right, but strstr should return a pointer to the substring which is "\r\n". By subtracting the location of the beginning on the buffer from the location of that substring, you should get the index of the substring.
Say the buffer containschar buf[] = "abcd\r\nefgh";
strstr should return the value of &buf[4].
So &buf[4] - buf equals 4. Using that, you can copy out all of the characters you want with strncpy.
Your code probably segfualted because strncpy DOESN'T put a null terminator at the end of the string.
if I have a function in C with a variadic signature, how do I express the type of the imported call in Haskell?
>>54698004
It's in rfc1459, irc proto specifies it.
I also specifically said this is unix sockets, in case you couldn't tell from the code which is clearly not winsock.
do you guys know if it is possible to write a scraper in C++ with minimal use of independent libraries (needs sessions, something like regular expressions, ideally a way of navigating an html tree easily, requests, and some way of easily submitting data (like headers and GET requests particularly. need something like a dict).

>>54698138
nope
>>54698143
oh. Well that simplifies things. Is it cross-platform?
>>54698161
think about what you are asking.
The .exe is not going to run on linux.
But you can definitely make it output elf
>>54698270
.exe files are very different from ELFs. An ELF file is a binary file for machine code (and a couple other things). .exe files are more like .tar files than ELFs.
If a python script is being built into an ELF it's being compiled.
>>54698270
I always wondered if it was possible to make cross platform binaries, but I guess the header wouldn't allow for that. Unless it ran off a script or something. It would end up being a waste of space in most cases anyways.

I'm changing a class with only static members (it's a MathUtil class) to a namespace.
But it's currently done in two files.
MathUtil.h
and
MathUtil.cpp
As you'd expect the .h only declares and the cpp defines.
So I can't just change the "class" in the .h file to namespace MathUtil because for some reason defining
MathUtil::Max(a,b){}
in the other file doesn't work?
How do I solve this without merging the two files and keeping the MathUtil:Max(a,b) usage?

Message is a pointer to a char array with 513 elements. It's a pretty unnecessary way to declare it. "char *message" would have been fine.
Considering the sizeof(char *) in the malloc, I think the original author is confused about that type too (although he uses it correctly in the realloc).
>>54697625

Just because people don't reply doesn't mean that they don't know, it means that they don't care.

Given how riled up so many get over minor details in languages like C; I think its fair to say that an error would be called out if the average /dpt/ fag could read x86 assembly.

Is it ADD if I can't sit through a tutorial without having it on at least x1.25 speed?
>>54700444
i don't think so. if you just want to get to the part of the tutorial that you don't know, then everything leading up to it is superfluous for you. this is why i find video tutorials really obnoxious when a text writeup would be fine. like i understand that most people won't read that, but imagine if a programming language reference document was narrated to you in a youtube video rather than made available as searchable, hyperlinkable text? it'd be excruciating.
i think it's a bad sign if you need all that information and yet you keep getting distracted, though.
help me /g/, i'm pretty sure i'm missing something simple but i can't figure it out. i'm trying to write an object into a file in the home directory of a user :/home/user/.Rbackub/jobFileString path = System.getProperty("user.home") + File.separator + ".Rbackup/";
File jobFile = new File(path, "jobFile");
FileOutputStream fos= new FileOutputStream(jobFile);
ObjectOutputStream oos= new ObjectOutputStream(fos);
oos.writeObject(listJobs);
fos.close();
oos.close();
it throws me the following
java.io.FileNotFoundException: /home/anon/.Rbackup/jobFile (File or Directory not found)
what am i doing wrong?
i already googled in case anyone wonders
this is a test do not reply to this
It keeps throwing ConcurrentModificationException even tho I don't modify anything, I only want to compare Objects with the equals method, does this count as modification as well?
halppublic boolean existeUsuario (Usuarios usuario){
boolean resultado = false;
Usuarios temp;
while (it.hasNext()){
temp = it.next();
if (usuario.equals(temp)){
resultado = true;
}
}
return resultado;
}

WHAT HAVE YOU SEEN TELL ME IM RETARDED
>>54700638
Name your variables in English.
Don't know a thing about Java, but I guessit.next()is your problem, it's not a local variable to that method, so it's modifying a member of that class, isn't it?
Somebody correct me if I'm wrong:
And object is more or less a named blob of stateful variables/functions.
Why on EARTH would I want something like this floating around in my program? Can somebody please explain how this isn't harmful as fuck? State is bad enough as it is; why is it in my interest to obfuscate it further?
>>54700601
>>54700674
Ye, will do next time but I thought the method is too simple to change it to english.
And you are right aboutit.next()it was giving me the error, but the error was because I didn't make the Iterator after adding the objects, silly mistake. My Iterator was inside the main Class and therefore it's useless if you don't have any objects inside the ArrayList before calling the class.
>>54700768
you are wrong.
>>54700786
Correct me then.
>>54700768

>>54700768
state isn't bad
it's like you fp fags didn't even read your tarpit manifesto yourselves
redundant state is bad
necessary state is fine
necessary state should be encapsulated to take away invariances users of your API can cause
that's what objects are for, encapsulation

how do i into reversing
I'm a bit overloaded lately, but I'm having a great deal of difficulty with all the terms and semantics of C++. I feel extremely stupid not being able to just throw it all together whether I like it or not, and read through it as necessary. Pointers are especially confusing.
eg://tell the compiler to allocate an address in memory as a pointer to an int
int* some_pointer;
//assign pointer the address of the 3rd element in an array
some_pointer = &some_fucking_array[2];
//use that which is pointed to for something
int fucking_variable = *some_pointer;
So what is all of this about "dereferencing"? Nothing is being dereferenced, the pointer is just being used as a means to store and access an address that might be somewhere in the heap, or anywhere. It's a proxy... a gateway... right? The pointer is not being altered by its use?
If this is so, why all the superfluous terminology? This is par for the course in just about any modern anything, but it makes me suspect there's something happening here that I don't understand.

>``encapsulation" is just a buzzword for "out of sight, out of mind"

i'm surprised some fp fags love advanced type systems but hate encapsulation
both have the same goal, you reduce invariances by limiting access to things
encapsulation achieves this at runtime while advanced type systems achieve this at compile time
since pretty much all type systems with dependent types are useless at this point, encapsulation is more than good enough to handle the corner cases your type system cannot handle
>>54700911

First, thank you for your question. What kind of reversing ?
>>54698648
>putting 'using' in code tags
>>54700927
>some fp fags love advanced type systems
Well I don't. I use Lisp.
>>54700926
But that's all they do, they just point at things, and allow fast access to objects without the need of copying things. In C++, however, as long as you're not allocating memory, you'd rather stick to references and iterators for such trivial things.
>>54700950
there are different kinds?
basically i want to map the layout of structures and functions used by a program so i can use it for my own purposes
>>54700768
I'm pretty much of the same opinion.
State is bad, and you should spend as much effort minimising it, not trying to hide it.
OOP is inherently flawed.
>>54700994
It seems I'm always trying to work from the bottom up. I don't even know how to pass by reference, and I'm stuck on figuring out how to decompress two image files and align them in memory to minimize cache misses when comparing their data.
Man I don't know how to live.

You can reverse engineering software, hardware, network protocols, ...
First thing to do is to subscribe to r/ReverseEngineering
start with that book http://beginners.re/RE4B-EN.pdf
train on crackmes
learn the isa that you are targeting.
learn calling conventions.
learn the underlying system API (posix/winapi/...)
learn gdb/ldb/windgb
learn ida pro/x64dgb
for hardware reversing, read http://bunniefoo.com/nostarch/HackingTheXbox_Free.pdf
you will need some electronic engineering and pc architecture knowledge.

If I code just for myself and for my portfolio, will I miss anything if I use VS community instead of VS enterprise?
Daily reminder Java is pass by reference by default.
>>54701478
java passes by value only. tard.
>>54701325
Nope, VS Community has basically everything.
The only thing I wish it included is the code mapping, but that's a drop in the bucket of the overall feature spread.
>>54701508
Objects are passed by reference. Only primitive types are passed by value by default.
>>54701564
Is MySQL usually used in conjunction with VS, or something else for databases?
partial application is based
>>54701581
based on what?
>>54701579
You can use whatever database you want.
Just make sure you have the ODBC connector installed on your machine for MySQL.

he's arguing semantics (technically, you are passing references to objects by value)

>>54701664
They mean that it was declared globally, which is often namespace pollution at best.
>>54701620
It depends on the application.
For example, two of our applications use a SQL Server database, and one of them uses a MySQL database.
I've stood up a data warehouse using SQL Server and the programs I write generally interface with that after it pulls data from the application databases.
Something like MariaDB (based on MySQL) is free, so would cost you nothing to play with.
Or you could use your free Azure credits for a hosted SQL Server database if you're just testing.

I seriously urge you to re-evaluate SSH for your task. It's proven technology, it works and it actually is secure. There are Windows SSH clients and servers. If deploying Windows SSH clients/servers is the problem because they want gazillion DLLs and whatnot, try statically compiling the program. You have its source code, because you aren't going to trust some closed-source piece of shit, aren't you?
If you really must design your own protocol, at least wrap it in an SSH tunnel to make it secure. Look up on libssh.

Please think. They posted their program, they are receiving feedback to accelerate their building of a logical framework. The length of this particular program is irrelevant.

Hey, I'm the first guy to wrap some communication in SSH and call it a day, but shit is just no fun.
It also fails to pass my second requirement, since to connect to an SSH server on a laptop I'll have to both know its IP and have a port magically open.
Because this thread failed to suggest alternatives, I guess I'll go with XMPP until I find something better.
I'll keep SSH in mind, thanks.
