Anyone know why this fails to write any output to the file??void pack_make_entry(const char* fname, uint32_t fsize)
{
uint8_t buff[32];
uint8_t c;
packed_file = fopen("gdata.dpk", "rb+");
rewind(packed_file);
while((c = fgetc(packed_file)) != 0x00)
{
fseek(packed_file, 32, SEEK_SET);
}
printw("%d ", ftell(packed_file));
memset(buff, 0xFF, 31);
fwrite(buff, sizeof(uint8_t), 32, packed_file);
fclose(packed_file);
}
I'm pretty new to C file IO, and it's seriously fucking me in the arse.
>>53840729
Oh, and excuse the unused variables, they're meant to be there, just unused atm.
>>53840729
>rewind(packed_file);
Unnecessary. The file will already be positioned at the start.
>fseek(packed_file, 32, SEEK_SET);
I don't know what the file is supposed to contain, but do you really want to seek to the 32nd byte each time you see something besides zero? This seems like it could easily cause an infinite loop.
>memset(buff, 0xFF, 31);
>fwrite(buff, sizeof(uint8_t), 32, packed_file);
The last byte of buff is uninitialised. Judging by your code, I assume you want it to be zero, but you have to do that explicitly.
>>53840795
Sorry I should clarify,
I'm going to be writing a struct that's 32-bytes long, hence I'm testing moving 32-bytes when I detect an entry is already taken. As for the second one, that was a typo lol, thanks for pointing it out.
>>53840810
fwrite still isn't giving me any output in the file. Is there some reason it would be failing to flush the buffer or something?
>>53840810
>>53840828
So you're trying to write a series of 32 byte structs to a file? Appending it to the end if some structs already exist?
>>53840862
Yeah, similar to how the FAT filesystem creates directory entries. I've got the logic for it all ready, but fwrite's just not actually making the change to the file. buff is just there for a quick 32-byte write test

>>53841051
In C++, right? I answered to you that passing the same exact reference was just a way to have a global that doesn't look like a global and in addition bloats your code. As for the namespaces, they exist to avoid name collisions, but don't create a namespace just for one variable. Also what is this variable for?
You didn't acknowledge me yesterday, you broke my heart ::(

>>53841207
*you know
>>53841157
I went out somewhere and actually lost the signal because my phone is brken. I even posted the question on the move.
The variable is a sort of a log. As the program works, it nicely writes out what it's doing in plain english. It calculates candidate keys for any given set of attributes and functional dependencies. That's why it's important to me that everybody appends to the same output string.
So where do I put that variable, in main.cpp, or do I declare it in all modules?
Also, I did reply, albeit, three or four hours later. Just in case.

>>53841347
When extracting the digits from an integer, it's very handy.for (; n > 0; n /= 10) {
emit_digit(n % 10);
}
>>53841278
Ok.
If you copy-paste the declaration, you're doing it wrong. AFAIK it should beextern std::string log;in a header so that all units have it declared;std::string log("initial contents");in one particular unit to define (here: construct) it.
Also maybe you want an ostringstream?

What's a good heuristic for the pacman food search problem?
The goal state is that pacman eats all the food pellets in the shortest amount of steps possible.
I've tried a heuristic where the predicted cost is equal to the manhattan distance of th farthest pellet.return max(map(lambda x:manhattanDistance(position, x), pellets))
It works but it's not really very effective.
I've also tried a greedier heuristic where you find the manhattan length of the closest pellet and then from that pellet the closest other pellet until you get to the last pellet (basically a greedy traveling salesman problem algorithm)
This results in a much faster solution but the result isn't always the fastest path available.
>>53841858
Consider a value exactly equal to n. If you add n, you'll have 2n/n and get 2. However, if you add n - 1, you'll be slightly less than 2n and truncation will give you 1.
If you have the value 0, adding n - 1 will give you (n - 1)/n. Resulting in 0.
If you have 1, 1 + n - 1 will give you n/n, resulting in 1.
Sorry, don't know how to format.

If x is a multiple of n, then we can say x = k.n, and we want k as the result.
Note that here, / is integer division (i.e. rounds down).
Then
(x + (n - 1)) / n = (k.n + (n - 1)) / n
observe that k.n < (k.n + (n - 1)) < (k + 1).n
therefore (x + (n - 1)) / n = k
Otherwise, we have x = k.n + m, where 0 < m < n, and we again want k as the result.
Then
(x + (n - 1)) / n = (k.n + m + (n - 1)) / n = ((k + 1).n + m - 1) / n
observe that 0 <= m - 1 < n
therefore k.n <= (x + (n - 1)) < (k + 1).n
therefore (x + (n - 1)) / n = k

I'm reading my first programming book.
>>53843624
Use the 6th edition, it also talks about ISO C11

>>53843624
>>53843658
Is this a good start for a complete beginner?
>>53843658
I have the 6th edition PDF, but I enjoy having the physical book in my hands more, I found the 3rd edition, in amazing condition at my local goodwill for $3.
>>53843682
I find it a very good ease into learning how to program so far, its got more padding than most C books as far as I can tell, being that its like, twice the length of a lot of recommended books, but I feel like it helps because they describe new things in great detail, and use multiple examples.
>>53843728
I don't mind it being long if it is actually helpful.
I just have this mental barrier where I think I can't learn to code on my own at all.

My first time using GitHub, how do I upload .java files into a repository?
I have them on my PC, but can't find out how to actually upload each of them onto each repository.
>>53843830
either use a GUI git client or type something like git add *.java and then commit

You can't. Linus, in his wisdom, banned ".java" files from the git spec.

If you're using Java, use an IDE like NetBeans or IntelliJ.
They already come with git support.

Also, not that anon that asked how to commit to git, I know how to commit to git. Haven't used git in 3 years or so, which is why I replied to that post

Unity support c++ plugins so you can pipe whatever want into the engine.

Not him, but you know fuck all if you think opengl is a rendering engine.
when i callnew QImage(bodyName.c_str());it only sets the value for the next n objects as the first value retrieved from bodyName.c_str(), as opposed to distinct values -- does anyone have any idea why?for (int i = 0; i < totalObjects; i++)
{
name = objectVector.at(i)->getName()+".png";
name.erase(std::remove(name.begin(), name.end(), ' '), name.end()); //remove whitespace from start of file name
QImage *image = new QImage(name.c_str());
QImage small = image->scaled(100, 100,Qt::KeepAspectRatio);
brushVector.insert(brushVector.begin(), new QBrush(small)); //default colour to be overriden

Most non-trivial libraries have to use non-standard stuff because you can't do much with just standard C.

>>53844341
I'm not claiming to be special, I'm just claiming that that other retard doesn't know what he's talking about. Having tried both opengl and direct3d in c++, I got tired of doing lower level things like that and decided my creative endeavours would be better off if some of those lower level things were done for me. C# is a much nicer language to use.

Also read the rest of the post where I talk about plopping it in the rest of my game which contains better shaders
>>53844383
>opengl
>low level
>>53844201
direct3d is literally just an api into the hardware. A full rendering engine handles the meshes, camera, animations, managing the textures, shaders, automating lighting and a tone of other features.
Using straight direct3d or opengl is fun as a project, but you'd be fucking retarded to go that low level for the majority of applications, unless you literally want to spend a year writing what other people have already done better.
Unity is full game engine as well, is royalty free, and saves you a ton of time. Its not "hard" to write a primitive game engine. But you're an idiot if you think you're going to write something better than Unity or similar by yourself in any reasonable amount of time.

Very well said
in C, say that I have a dynamically allocated struct containing a 2d array, what's the proper way to free the memory?
>>53844566
free(ptr)
>>53844591
I was wondering if I should also free the array if it's dynamically allocated
test
>>53844610
Define a destructor delete[] the array. The delete the struct.
Got my C compiler to compile some crypto programs, and to my surprise, they worked!
Feels pretty great when this piece of spaghetti manages to get some shit done.

Are you retarded?
>>53844651
>>53844740
Thought c++ immediately because freeing in c is easy. Just free for every time you malloc.
if C added function overloading you'd be able to just overload free to do something different for user defined structs
>>53844932
you can do that with that new generic macro thing in c11
Need some help implementing the selection sort algorithm (instead of bubble sort) into this JavaFX program: http://pastebin.com/HjEjg7m9
Yes, this is my homework:
Write a Java program that animates the selection sort algorithm. Create an array that consists of 20 distinct numbers from 1 to 20 in a random order. The array elements are displayed in a histogram, as shown in Figure 23.20a. Clicking the Step button causes the program to perform an iteration of the outer loop in the algorithm and repaints the histogram for the new array. Color the last bar in the sorted subarray. When the algorithm is finished, display a message to inform the user. Clicking theReset button creates a new random array for a new start.

You dummy. Plus what's so complicated about insertion sort?
>>53844725
what does that even do
Well while working on one of my development servers, I fucked the OS, grub repair failed, well then, reinstallation of the OS it is.
>>53845195
>>53845214
http://pastebin.com/TptQX4FB
Sorting algorithm should be something like:
static void selectionSort(double[] list) {
for (int i = list.length - 1; i >= 1; i--) {
double currentMax = list[0];
int currentMaxIndex = 0;
for (int j = 1; j <= i; j++) {
if (currentMax < list[j]) {
currentMax = list[j];
currentMaxIndex = j;
}
}

https://en.wikipedia.org/wiki/Risch_algorithm
It's still not implemented completely
>>53845489
an algorithm can be made to be arbitrarily complex
>>53845269
Here's a correct selection sort. Now rewrite it in a step-by-step way and plug it in your program.static void sort(double[] arr) {
for (int i = 0; i < arr.length; i++) {
int min = i;
for(int j = i+1; j < arr.length; j++)
if (arr[j] < arr[min])
min = j;
double temp = arr[i];
arr[i] = arr[min];
arr[min] = temp;
}
}

Read the C standard, especially the first couple sections regarding environmental limits and you'll quickly realize just how limited 'standard, portable C' really is.
Prior to C11 you couldn't even make threadsafe programs without compiler extensions for example.
