I shouldn't need to malloc tiles at the beginning like you see, I had that there in case anyone said that was good or not. (Although at this point it does stand in the code). When the level is being parsed, a layers tiles are allocated AFTER all the other layer information is figured out:LVL.LYR[l].tile = (int*)malloc( sizeof(int) * LVL.width * LVL.height );
If I ran:LVL.LYR[l].tile = (int*)realloc( LVL.LYR[l].tile, sizeof(int) * LVL.width * LVL.height );
instead, I would get a crash. l is the number that keeps track of the number of layer nodes. At the beginning of finding a layer node:if( l > 0 ) {
LVL.LYR = (struct layer*)realloc( LVL.LYR, l * sizeof(struct layer) );
}
And at the end of finding a layer node, l would go up one for next time (if there is a next time). This works correctly, but it's here if someone asks to see it.
where the game crashes isfree(LVL.LYR);
I said yesterday I might work on it, but sadly school/work sucked up all my free time (video editing/SQL reports).
What I can do, is make a backup of my current project, and change the structure system so that no struct has a struct within it.

How to Create a Successful Open Source Project
1. Give it an unpronounceable name. Better if it's an acronym.
2. Under no circumstances must you ever tell people what your software actually does. The first thing on your website should be a brief description mentioning that it's modular, multi-threaded, open source, and what programming language it's written in.
3. The next thing on the website should be a Recent Announcements section. Mention that you released version 3.4.8 and fixed bugs #42135 and #47892.
4. Auto-generated Doxygen pages are always a substitute for a real manual.
5. Installers are for babies. Force users to compile from source and find all the dependencies themselves. Bonus points if you make them choose a mirror instead of having a single download link.
6. Have a bug database, but never acknowledge anything on there. Either ignore it or mark everything wontfix.
7. Break compatibility often.
8. Refer to yourself as a "Foundation". You aren't just a fat guy living with your parents. You're a foundation and need donations.
9. Have an outreach program for women. Letting women decide how to spend their free time for themselves is sexist. Telling them what to do and pressuring them into a field they aren't interested in is progressive.
10. Abandon the project. Remove all dates from your website so nobody realizes the latest release is actually 7 years old.
ok /g/uys, I have a problem with C#.
I have this list that I'm trying to assign a value to (I've tried a = b and a.Add(b)) but it keeps throwing me a NullRefrenceException. I find this sort of strange since...
Ofcourse the list is null, that's why I'm trying to set a value to it.
Anyway, Declaring it :public static List<String> pics,oldpics,newpics = new List<String>();
(this is in the vars class btw)
Triying to set a value to it for the first timevars.i = 0;
foreach (string pic in pictures) {
vars.pics[vars.i] = pic;
vars.i++;
}
(this is happening inside the Deserialize function that's being called from the Check function)
Main :public static void Main () {
Input ();
if (!Directory.Exists(vars.downloc)) {
Directory.CreateDirectory(vars.downloc);
}
while (true) {

OP here from previous thread that asked question about the missing digit problem >>46460474
Lets say i pic the number 326. I add the digits and get 11. Subtract that with 326 and i get 315. I give the computer the digits 1 and 5. I add 1+5, getting 6 which i divid by 9. That leaves me with a remainder 6 which if i subtract from 9 i get the missing number which is 3.
Is that the correct way to find the missing digit?

There's your problem. You define three variables. Only newpics is ever assigned to anything. If you want pics and oldpics to be new lists, you have to do the "= new" thing each time.

Look up sizeof in the structs chapter on K&R. The sizeof a struct may not always be the sum of the sizes of its members.
l is a shity variable name because it's a single letter (which means it doesn't tell anything about what's supposed to represent), and can be easily mistaken by a 1 or a capital i.

the 80 character max is deprecated as fuck. it was relevant when we used punch hole cards, and those were only that size because of the size of U.S. dollar bills a century ago. when you have 4K or 8K monitors in portrait mode, will you still only have 80 characters per line? just reduce the font size and have whatever width you want. don't force a bunch of line breaks that lack any semantics or short undescriptive line breaks just because you have some autistic idea in your head that it has to be less than 80 characters per line.

Yes because I want vertical splits of the same or another file, pdf or web browser on the side, etc.
It's also generally harder to read longer lines because it takes more effort to scan back to the beginning of the next one since the distance is so huge.

GUYS GUYS!
I can't figure this shit out!
okay so I was in the other thread trying to screen out negatives through a while loop and I succeeded.
I said
while (entered_int < 0)
{
cout << " Please enter positive whole numbers only!"
cin >> entered_int
}
it works, but then I also have to screen characters!
so I used this loop
while(!(cin >> entered_int))
{
cout << " Please enter postive whole numbers only";
cin.clear();
cin.ignore(std::numeric_limits<std::streamsize>::max(), '\n');
}
righ right! They both work, but heres the problem! I don't know how to combine both of these while loops to screen out either one.
I mean, I just wan thte user to input integers that are not negative or characters.... ugh! I'm almost done too.
can someone help me out really quick, please?
>>46463634
Would this not work?while(!(cin >> entered_int) && entered_int < 0)
>>46463694
nope.
Its weird, this is what I'm trying to run now, but it screens out characters but when I input a negative integer, it just skips line on the command line
while(!(cin >> entered_int) || (entered_int < 0))
{
cout << " Please enter positive whole numbers only!!";
cin.clear();
cin.ignore(std::numeric_limits<std::streamsize>::max(), '\n');
}
>>46463694
damn, i don't how, but I made it work lol!
I switched it up like this,
while((entered_int < 0) || !(entered_int))
{
cout << " Please enter positive whole numbers only!";
cin.clear();
cin.ignore(std::numeric_limits<std::streamsize>::max(), '\n');
cin >> costumer_ID;
}

Hey /g/, a question
I am a JavaScript dev using GNU/Linux. I am generally OK with that since browsers work the same everywhere anyway.
Well, now I need to debug some C++ code that I need to get working, and I find all the debugging tools quite lacking. I found several gdb frontends, but they all either don't work or suck. (Especially compared to picture related.)
Nemiver sucks because it lacks even the most basic functions. Kdbg is KDE so it sucks by definition (it doesn't even run here, no idea why). Ddd is the only one that actually works but it has user interface from 1999.
Do I seriously need to learn GDB?

Java guy, never really coded c++ (and the << overloading is still breaking my heart) , butstd::cout<<name()
takes the result of name and puts it into cout. Result of name is nothing, it cannot put that into cout.
The fact that the side-effect of name() is printing "steve" into cout is another thing. But the result is nothing, you cannot put that into cout.
Change name() from void to string and return "Steve" from the function
function min(a,b) {
if (a < b){
alert(a); }
else {
alert(b);} }
Is this clean code? I'm learning JavaScript and understand a lot of material, I'm just worried the code quality is disgusting...
>>46465261
No, it's shit code.
Don't use alert unless you really really need to. Use console.log(...) for internal stuff/debugging, and for actual user interaction, just write that stuff onto the page. Alerts are ugly and stupid.
Don't use this weird style of closing braces. Some people would write it like thisfunction min(a,b) {
if (a < b)
{
alert(a);
}
else
{
alert(b);
}
}
Other people would write it like thisfunction min(a,b) {
if (a < b) {
alert(a);
}
else {
alert(b);
}
}
Some people (like me) like this
function min(a,b) {
if (a < b) {
alert(a);
} else {
alert(b);
}
}
No people write it like you. The point is - the closing brace should be on the same "level" as the opening one, so you can quickly look at it and see what belongs to what
>>46465354
Fuck, the last one should befunction min(a,b) {
if (a < b) {

A binary parser in C++... Before I started learning C++, I wondered why anyone would bother with Java. And now that I've learnt a bit about the language, I think Java is an over complicated brick of shit. Take any given C++ library, and it's Java equivalent, and so long as you've grokked the basics, the C++ version will be far more legible than the bloated and over engineered Java equivalent.
It's not even funny, as there are a lot of Java builds out there.
I think Java took hold in the mid to late 90's, because the lecturers had not a clue about how to teach C++, and didn't want to admit it.

Same with camelCaseStyleOfNamingProcedures() and underscore_style_of_the_same(). Just pick one and use it (and take into the consideration the conventions of the language.... underscore style in Java for example is stupid, while javascript has no conventions and every project is different)
I wanted to say something about spaces around === and + etc. but then I realized I am the worst offender of this since I put them randomly as I see fit so yeah, I will shut up about that, haha
>>46465425
C++'s std might be nice, but if you take any other library written for the language, it will be just as complicated if not worse than the Java equivalent.
Part of this is due to how horrible C++ is as a language. There are so many rules and contradictions that have been tacked on over the years such that C++ is now nearly a sunk ship.
Java, however, was purposefully designed for stupid people, so the language itself is much simpler. A consequence, however, is that the libraries designed by Java developers are often horrendous.

i'm guessing that i have to keep a 1:1 copy of the GPU-side stuff in floatBuffer? this just goes against my previous conceptions of how this works. glDrawArrays doesn't seem to just work with whatever floatBuffer's position is, it seems like the position has to be exactly the same as the starting point of the destination in the vertex buffer object. so if i only want to create floatBuffer once then it has to be as large as the most memory the GPU will ever use?!
>>46465526
I use the same rule of thumb as a use for any library or framework in any language. If key routines have stupid names, or if the tookit does nothing in particular, then I'll walk away.
This happens more often than not in Java, but less in C++. Javascript is going through a particularly interesting trend right now. It all started badly for Javascript, because the core library was stupid. Then JQuery came along (like Boost for JS), and people started to write some decent shit. The sheer genuis of JSON also helped a lot. Then the Java devs got hold of it, because they realized how stupid the JSF and GWT approach to web development was, and now, with the likes of Angular JS and Backbone, people are starting to write odd JavaScript libraries that have no specific purpose again.
>>46465138
1. void has no return value. The << operator is going to two distinct objects on each end of it. One of the types it is overloaded for is std::ostream& and const char*, which returns another std::ostream&. So cout takes steve, returns cout is an example of this. Now, imagine if you had written this:cout << "This C++ program is written by " << /* */ << end;
It's as if there was no expression there. That's because there isn't, because void isn't a type and doesn't return anything.
Also, stop doing system("pause"). Permanently.

Okay so my level works now that I got rid of the LVL struct. Layer and Object are their own independant structs now. Everything is like:char *lvlName = NULL;
int lvlWidth = NULL;
int lvlHeight = NULL;
int numLayer = NULL;
int numTile = NULL;
int numObject = NULL;
struct layer *lvlLayer;
struct object *lvlObject;
When I deinitialize:void lvlDeinitialize() {
lvlName = NULL;
lvlWidth = NULL;
lvlHeight = NULL;
if( lvlLayer != NULL ) {
free(lvlLayer);
lvlLayer = NULL;
}
if( lvlObject != NULL ) {
free(lvlObject);
lvlObject = NULL;
}
}
When I initialize:void lvlInitialize() {
lvlName = NULL;
lvlWidth = NULL;
lvlHeight = NULL;
lvlLayer = (struct layer*)malloc( 1 * sizeof(struct layer) );
lvlObject = (struct object*)malloc( 1 * sizeof(struct object) );
}
Parsing them is the same more or less. One sublte memory issue, but I think it might have something to do with not freeing the tiles first.

I'm not really sure a language needs a design to be good. C++ might be a little inconsistent on syntax, but more or less, it does what it needs to do. It's "we need a language with the speed of a systems programming language and any and all features that might be more useful as a general purpose language."
>>46465821
Vectors shouldn't take up more memory per element, just a small amount of memory overhead for keeping track of length, capacity, and of course, a pointer to the first element, or something to that degree.
As for whether or not they are better... it depends upon whether or not you need a resizable array. If you don't, then just use a regular C array or an std::array. If you do, then std vectors are likely a better solution than rolling your own.

9 times out of 10, you want to use std::vector. The only time you use anything else is when you're _absolutely sure_ that you need a statically sized array. If you're even a little bit unsure which one to use, use std::vector. It saves you the headache of retrofitting it later.

>>46466829
>It (the window) doesnt stay open long enough for me to see the output. idk how to fix that
That's actually Window's fault because it doesn't care about whether it should keep its window open long enough for you to read the output. If you run the program directly from cmd.exe (instead of clicking on the .exe), the terminal window will stay open after the program terminates.
Alternatively, you can write a .bat file that runs your program and pauses the terminal so that you can read it:
In the same directory as your program, open a text file and name it run.bat. Then put this in it:@echo off
name-of-my-program.exe
pause
where you replace "name-of-my-program.exe" with the actual name of the exe you're generating. Then, you can click on the .bat file, and it'll run your program in a terminal window and ask you to press enter before closing it.

thats not the issue though. the issue is that it then says

I agree that it's important for any competent C and C++ programmer to know what UB is and what kinds of code can lead to it, but he seems to be a beginner programmer, and it's not worth inundating him with information now because he'll just be discouraged from continuing the learning process. For someone in the middle of the learning process, it's more important that they aren't blocked with what they want to do, than that they learn all the details of the correct implementation because they're more likely to give up than go through the all the side-work.
Looking back, I probably should have told him that this situation is called "undefined behavior", and he could have Googled it later. That said, I think it's easier to tell a beginner "the program doesn't know what to do" rather than saying "your implementation elicits undefined behavior" because a beginner will more easily grok the first explanation, IMO. He can learn the full extent of UB after he understands the fundamentals of programming (for example, that non-void functions should always have a return statement).
>>46467363
You need to keep a list of integers you've found to be adjacent, and an extra int to keep track of the previous number the user put in. Every time you read a number, check if it's equal to the last number they put in. If so, append that value to the list of adjacents. Finally, update the previous int value with the newly input value for the next iteration of the loop.
Does that help?
>>46467363

all you need is a PreviousNumber integer and a Duplicates array of integers. If PreviousNumber = Input Then Add Input To Array
then just print the array

it's the same thing as what >>46467402 said with "list of integers".

instead of an "array" you can just append the newly repeated number to a string, that way you can print it.

Don't set non-pointer variables to NULL. You also need to initialize lvlLayer and lvlObject:char *lvlName = NULL;

int numObject = 0;

>>46467417
you could have just said proxy
>>46467872
>-99, since if that's the first number they enter it terminates anyway
If he does that, he'll have to be careful to make the -99 check in the loop before making the check for adjacent integers. Otherwise, he'll end up adding -99 to the list.
Personally, I'd just special case it and add a "is_first" bool. Sure it's an extra check, but with branch prediction, it's free anyway. Plus, I'd say it's easier to read since you don't have to understand that input ends on -99 to know that you're skipping the first number.
>>46467915

so far, this is what i have:Create PositiveCount as integer = 0

Create Input as integer
Create PreviousInput as integer
Create AdjacentString as string
Write “Please enter an integer:”
Get Input
Write “Your cumulative total is:” CumulativeTotal
If (Input = -99)
Write “You had” PositiveCount “positives”
Write “You had” NegativeCount “negatives”
Write “You had” ZeroCount “zeros”
Else (Input > 0)
PositiveCount = PositiveCount +1
Else (Input < 0)
NegativeCount= NegativeCount +1
Else (Input = 0)

I don't see anything weird in that output. It looks completely normal. Those aren't line numbers, they're offsets; and they're supposed to look like that. Your "what it should be printing" is wrong. It can look like that, but it does not have to.
You're getting that error because the linker doesn't know where the function PatBlt is. That's a Windows GDI function, so you have to link with gdi32. That is, put -lgdi32 on the command line.

>>46468994
What does it matter how the message looks like? The latter error is reported by the linker, it does not have access to the source code, it does not know anything about line numbers. It only knows offsets. You get the former error from the compiler if it can detect the error and can pinpoint the exact location of the problem. The compiler has access to the source code.
I can also tell you that adding -lm to the command line has nothing to do with your problem.
>>46469161
Then don't read the hexadecimal part. You don't need that right now. The relevant part isundefined reference to 'PatBlt@24'
Everything else is just noise you can ignore.
Your compiler will give you the error message when it can. Why it reported the missing function earlier and now doesn't, I don't know. It's not my machine, I don't know what you've done. You will get error messages with line numbers and even column numbers when the compiler can give those. When it can't, the linker will complain, but with offsets. Live with that.

Anyone here experience with MVC in PHP? Trying to write a CMS but have no idea how to start.
I am learning ia-32 asm and am now trying to traverse a linked list.
I don't really know how, though.
Each node has a 32 bit number and the 32 bit address of the next node directly following.
I've got the address of my first node in eax.
Getting the first number is easy and to get the address of the next node I just add 4 to eax (address is directly following, so 4 byte after start of number). Now eax is the address of my next address.
But how do I get the actual next address into eax?
mov eax, [eax] doesn't seem to work

1. Build a time machine
2. Travel back to 2001
3. Build a CMS with PHP.
You're welcome.
>>46471199
I already have my CMS, but it is unstructured and based on if else statements (80 LOC). Thought MVC would be a good way to structure it and maybe implement a backend and a plugin system.
whats some useful stuff to make in C? things like a linked list and other utility things

A linked list is a good idea. Write your own stack. Make things like that, it will help you to learn a lot about these structures.Only if you want to learn more about things like that
Is it possible to make a firefox addon which upon right clicking a link, allows a "Open link location in mpv."?
Is it possible to launch other programs from a firefox addon?
I MADE THIS FUCKING AWESOME PROGRAM!!!#include <stdio.h>
int main(int * argc, char * argv[])
{
char fil[1024], nam[10];
int len, wid,a,b,c, cou=0;
srand(time(NULL));
len = 500;
wid = 500;
while(atoi(argv[1]) > cou)
{
a = rand() % 255;
b = rand() % 255;
c = rand() % 255;
sprintf(fil, "<svg>\n<rect width=\"%d\" height=\"%d\" fill=\"rgb(%d, %d, %d)\"/>\n</svg>", len,wid, a,b,c);
FILE *f;
sprintf(nam, "%d.svg", cou);
f = fopen(nam, "w");
fprintf(f, "%s", fil);
fclose(f);
memset(nam, 0, sizeof(nam));
memset(fil,0,sizeof(fil));
cou++;
}
}
Yeah memset because i have worked far too long with low memory bullshit.

Worked it out. You have to download this addon
https://addons.mozilla.org/en-US/firefox/addon/open-with/
Then create shell script at /usr/bin/mpvy#!/bin/bash
mpv $( youtube-dl -g $1 )
Make it executablechmod +x /usr/bin/mpvy
Then open about:openwith and add it as a command. Fiddle with the settings to get it to appear where you want.

Learning java and have a more work ethic regarding question:
How can you do your job without caffeine?
Or without food breaks?
How can you convince your colleagues that their lifestyle and your company's recess ethic and party mentality is very detrimental to your Health and can't join in all the time?
I heard that people are just intermittently fasting to ensure nothing wrecks havoc on their bodies until after work and a heavy workout, where they eat normally.
And they take whole naps.
How can I convince my employer that taking a good sleep as a flexible recess is better than a fixed one?

Why are you making your for loop indices doubles? Just do int.
>>46472275
I've always done everything by myself when learning to program.
Seriously, is was like 15 and no one around me knew anything about programming, and I was to afraid / did not know how to ask questions on the internet.
This is why I refuse to help some people with things that they can solve themselves after spending enough time with the problem. If that guy spend an hour researching by himself he could have figured it out.

Nice solution otherwise.
>>46472366
this. even if you spoon feed some of these people with the exact same solution that worked for you, they'll put about a thousandth of the effort you put into writing the answer (let alone finding out the solution in the first place) and decide that it didn't work. stupid, lazy, unpassionate, ungrateful cunts.

Either you use a C++ compiler for a C source, and you are retarded.
Or you use malloc in a C++ program, and then you are even more retarded.
Go die in a fire faggot.
>>46462883
Exact. Except, you don't use malloc in C++.
i want to make a code that's count the numbers between what the user entered in python .. im gussin i should use xrange or while but i have no clue how to start
>>46472835
Subtraction. Do you even kindergarten level math?

Not that guy but using gcc -std=gnu99 will give you a warning for not casting a malloc

Alright, guys, I'm working on a school project about NFAs.
My partner is handling conversion to DFAs, and had some old code from his last attempt.
I'm trying to fix the intersection between two DFAs, and it's not working out too well.
The approach the code takes is:Keep a counter for the 'current' node.
For every node in a2: = n2
For every node in the current automaton: = n1
First, add a node in the new automaton, with the same 'order' (start | finish | etc) as the intersection of n2 and n1.
If no special intersection is found, it's just a normal node.
This seems to work, as far as I can see.
For every edge that starts in n2: = e2
For every edge that starts in n1: = e1
if the values are the same:
add a new edge from this node, with that same value, to another node with id 'n2.id * nodes in n2 + n1.id'
else:
add a new edge with the same value as e1 that goes to n1.id
add a new edge with the same value as e2 that goes to 'n2.id * nodes in n2 + n1.id'.
This doesn't work. Could someone explain to me what I'm doing wrong, please?

Make a main() function, then save your two numbers in the main function by running the 2 other functions.
def main():
num1 = ask_number
num2 = ask_number2
for n in xrange(number, number2):
print n
>>46473195
Sorry I totally fucked that up:
def main():
num1 = ask_number()
num2 = ask_number2()
for n in xrange(num1, num2):
print n
I should proofread better.
