That's much better, but it's still horrifying. I'm sure the piss-poor variable naming contributes to it though.

Citation very needed. Most C implementations of fizzbuzz and hello world (the two things C programs ever program) both work in C and C++.

It was in the reply tree.

Well, casts can't never mean that. If they did not understand a well defined term like this, it's their problem.
Also, only a few dumbfucks (like you) were unable to understand.

Same for C++, it's shit
>>55560620
the mere fact that you think casting to/from void* matters shows that in C you use void* a lot more than in C++, in C++ you don't have to use them at all (you don't even have to use malloc) except when using C libraries/APIs, and this ties back to your original comment, just because you have to do an explicit cast instead of an implicit conversion the rare few times you use a void* doesn't (in itself, at least) disqualify C++ from being "nice"

use the code tags bro'code here'
>>55562238Oh, you can nest them!
>>55562175
how do you want to compare them ?
Count the correct ones or, compare if they are the same
if the latter, then just do correct == userAnswers
if former, than do a loop and count correct answers - simplest, or use some functional tools maybe less simple if you are a beginner

I want to return both the number of "correct" answers and what ones don't match
Basically all in all it has to accept user answers, compare those with the answer list, tell the student if they passed of failed (15 or more matches), the total number of correct answers, the total number of incorrect answers, and a list of the incorrect answers
hi DPT,
I have a little dilemma.
Fucking Noob here. I've been learning python to make little tools (simply equation solvers I can use at work)
None have a GUI yet or anything and all are run from the console.
I intend to make them into a single coherent application eventually.
The issue is that I figure the best way for me to have access to these applications is via a web interface of some sort. I have a wordpress site hosted on my own server currently up and running.
I can't for the life of me find a reasonable way of getting a webgui working with a python script without mixing two different languages and passing variables back and forth from the wordpress to a python script hosted on a server.
I'm wondering if I should jump ship to a more web-compatible language to make my life easier.
Hello /g/uys! I need some help with randomness in C. I've got this code which is not random at all and I have no idea how to fix it... Any Idea?
Code:int randBetween(int iMin, int iMax){
srand(time(NULL));
return rand() / (RAND_MAX + 1) * (iMax - iMin)+ iMin;
}
void randomizeUpdateData(){
TCHAR szPath[MAX_PATH];
strcpy(szPath, "C:\\Program Files\\GoogleUpdateService\\UpdateData");
int iLen = 42;
for(int i = 0; i < 5; i++){
Sleep(10);
szPath[++iLen] = (TCHAR) randBetween(48, 58);
}
for(int i = 0; i < 7; i++){
Sleep(10);
szPath[++iLen] = (TCHAR) randBetween(97, 123);
}
TCHAR buf[256];
for(int i = 0; i < 256; i++){
Sleep(10);
buf[i] = (TCHAR)randBetween(0, 255);
}
printf("%s\n%s\n", szPath, buf);
HANDLE file;
file = CreateFile(szPath, GENERIC_WRITE, 0, NULL, CREATE_NEW, FILE_ATTRIBUTE_NORMAL, NULL);

What's the best way to upload light source data to a GLSL shader?
I'm currently using uniform buffer objects, but there's a few problems I'm not comfortable with.
A. In GLSL, buffer backed interface blocks cannot have variable sized arrays, only static arrays, forcing me to specify a fixed upper bound on the maximum amount of lights possible.
B. The size taken up by the interface block is always the size you declared it, not the size of the buffer object that backs it, which magnifies the above problem.
C. UBO's have a small size limit (16K to 64K on most implementations).
On an implementation that only supports 16K UBO's (like intel, which I'm on), that means I can only upload about only 2000 lights at most (not enough for me).
D. Shader storage objects are only supported on GL 4.3, I'm on 3.3 hardware and even if I was on 4.3 hardware I'd still only target GL 3.3 core profile.

I'd prefer using srand as i need to have the smallest amount of code, possible. Apparently I'm not using the function right so I wanted to know how to fix it.

Should be trivial to translate this to python. It's prob what your prof is expecting for the homework.int main()
{
int Count = 0;
std::vector <char> A = { 'b', 'd', 'a', 'a', 'c', 'a', 'b', 'a', 'c', 'd', 'b', 'c', 'd', 'a', 'd', 'c', 'c', 'b', 'd', 'a' };
std::vector <char> B = {};
std::vector <bool> Matches = {};
char temp;
for (size_t i = 0; i < A.size(); ++i) {
std::cout << "{" << i << "}" << "Enter answer: ";
std::cin >> temp;
B.push_back(temp);
}
for (size_t i = 0; i < A.size(); ++i) {
if (A[i] == B[i]) {
++Count;
Matches.push_back(true);
}
else {
Matches.push_back(false);
}
}
std::cout << "Count: " << Count << "\nMatches: ";
for (auto i : Matches) {
std::cout << (i ? 'T' : 'F') << ' ';
}
std::cout << std::endl;
return 0;
}
Where can I find some decent QT codebases?
>>55562555
you should run srand(time(NULL)) only once, because right now you reseed the random generator every single time
>>55562583
I thought seeding it every time I need a random number will result in more randomness...

I don't really understand all the Jargon.
Django is a 'framework' for python.
What does that mean and what does it allow me to do?
I know WP is based on php, so I wouldn't be able to work my current site setup with Django.
Can I install Django and a compatible CMS on the same server as my "Nginx,php,mysql,WP" site, then have wordpress embed that page?
Or am I missing the point here?
>>55562575
No where.
>>55562617
if you reseed it fast enough, you get the same seed
it's based on current time in seconds

>Django is a 'framework' for python.
It's a web framework written in Python.
>What does that mean and what does it allow me to do?
When it comes to dynamic content for websites and using databases, a web framework helps for speeding things up, providing useful tools and security benefits.
WP and Django won't mix. If you've heard of things like Symfony and Laravel, Django is similar to those, it's not a CMS. The typical setup for Django is nginx, postgresql, uwsgi/gunicorn.

if (board[0][0] == board[1][1] == board[2][2]) or (board[0][2] == board[1][1] == board[2][0]):
if board[1][1] == 'X':
print ("Game over - Player 1 wins")

print ("Game over - Player 2 wins")
reset()
def reset():
board = [["#", "#", "#"],
["#", "#", "#"],

Why wont something like this reset the global variable "board" when the winner condition is met?
It just announces the winner and asks for the input again but the board is the old game board
>>55564146
because scopes
>>55564167
but board is a global variable, when reset() is called it should be able to redefine it again

And? You can have a list inside the class.
I'm trying to program a function that, given a vector with elements numbered 1-15, picks one at random and places it in a 2-D array.
The problem is, every time I run the code, I get the exact same numbers from the random number generator (see pic related. Left column is random number, right is contents of vector)
Here's my code:int randNum = rand() % numberVector.size();
std::cout << randNum << " || \t"; // Prints index
printVec(numberVector); //Prints contents of the vector
playableSet[i][j] = numberVector.at(randNum);
numberVector.erase(numberVector.begin() + randNum);
>>55564434
Seed the rand()-fnction with srand(time(NULL)). But not in every loop cycle, this would just recreate the underlying number-table of rand() for ever and ever (in this very second of your system-clock)
I think there's something wrong with my surface normal.
So as far as I know, positive X direction goes out of the screen while the negative X direction goes into the screen, so I have setup my light source to hover above the 2D plane that fills the entire screen:light lights[] =
{
{
.pos = {0.5, 0.7, 0.5},
.col = {1.0, 1.0, 1.0},
},
{
.pos = {0.0, 0.0, 0.5},
.col = {0.7, 0.3, 0.5},
},
{
.pos = {0.05, -0.55, 0.5},
.col = {0.3, 0.6, 0.2},
},
};
And I upload that to the GPU.
Now in my GLSL shader where I do a very simple light calculation (dot product of surface normal and normalized direction of light):for (int j = 0; j < n_lights; j++)
{
Light light = lights[j];
vec3 pos = vec3(fs_pos, 0.0);
vec3 dir = normalize(pos - light.pos);
float i = clamp(dot(vec3(0.0, 0.0, -1.0), dir), 0.0, 1.0);
color_out += vec4(light.col * i, 1.0);
}
This works, however there is a slight problem with the normal, it's facing downwards, but it works. the fuck?
My light source is ABOVE the plain, and I'm pretty sure I'm calculating the direction correctly, and I'm pretty sure that the position Z direction goes UPWARDS (towards you), yet my fucking surface normal has to be facing DOWNWARDS (away from you) in order for my lights to light up the scene.
What the fuck am I doing wrong?

Where can I get good exercises online where I can actually THINK of a solution, instead of the website spoon feeding it to me?I just want to practice my programming skills, but I feel like this is like math, looking at steps won't help unless you start practing.
god damn it, i have a fetish of a sort.
i mostly get a stiff whenever i find an efficient way to to solve a problem.
and now i'm into programming, and working on an android app.
the app works by exchanging data with an api that returns it in the form of JSONobject.
the reason i can't rid my self from this fucking hardon is that the ways i found seem pretty shit from a performance stand point and pretty illogical.
Am i to use AsyncTask for every single little connection needed? The app is heavy on that side, so won't it flood the device with a multitude of threads when there isn't a decent connection on?
I figure i would use caching, and it would solve my problem a bit.

I think you should only seed the random number generator once. So I usually put the srand line in the main part of my program. Beginner myself so take my advice with a grain of salt.
