first for C++ is a good language
I want to print numbers like this:
1 and 1
1 and 2
1 and 3
...
1 and 20
2 and 1
2 and 2
2 and 3
....
19 and 19
19 and 20
It is stopping after 1 and 20, how do make it work?
Python newb here.
Simple, simple question, hope you can help me:
How do I add a string to a regex?
Say: d = '\d\d\d'
mo = re.compile(r #d goes here)
Pasting it, separating it with a comma, or with a plus gives me errors.
Normally, as you know, it would be re.compile(r'\d\d\d')
>>53656035
Learn to use for loops.#include <stdio.h>
#define MAX 20
int main(int argc, char** argv)
{
int i, j;
for (i = 1; i < MAX; i++) {
for (j = 1; j < MAX; j++) {
printf("%d and %d\n", i, j);
}
}
return 0;
}
>>53656035int
main()
{
int inner, outer;
for (outer = 1; outer < 21; outer++)
{
for (inner = 1; inner < 21; inner++)
{
printf("%d and %d\n", outer, inner);
}
}
}
>>53656038
You can just compile a string
re.compile('\d\d\d') works

>unnecessary macros
int script_lock = 1; //lock is open
while (true) {
if ( script_lock == 1){
script_lock = 0; //lick is closed
auto future = async (script, execute);
auto status = future.wait_for(chrono::milliseconds(0));
if (status == future_status::ready) {
script_lock = 1; //lock is open
}
}
//do something
}
When the program runs inside the while loop it will only run the thread if the previous thread has closed. Problem is once the lock is set to 0, and closed off inside the loop, I can't access the loop again to retest if the thread is still running or not. How can I get around this?

The whole point of the libraries is so you don't have to implement the complex math required. All you need to worry about is how to implement it into whatever project you're working on.

Thanks. I was trying to do that using while loop. My aim is to find prime numbers using this method. It will give a list of prime numbers from 1 to n, we enter n. I just started to learn c programming. I learned how to use arrays and pointers. Just to make sure, is it not possible to do that using while loop?
>>53656388

>>53656388
Prime numbers are hard for computers. It's the whole reason RSA works so well. The best prime checking algo is the AKS and that shit is still O(log(n)^6)
>>53656388
Any for-loop can be rewritten using a while loop. In that case, a for loop is easier to write

yes. system issues a command and that is explicitly a windows command. And it suspends the program which is unnecessarily retarded.

So... here's the deal... you're running it wrong. If you're writing to stdout and reading from stdin, you're using what's called a console program. This is in contrast to a GUI program. A console program is intended to be run from within the context of a console -- a command line interpreter -- or a shell script run from a console. The program is invoked by providing the console a relative path (or just its name if it is stored in the console's PATH environmental variable), and the program is spawned as a child process of whatever shell it was launched from. It may optionally have its stdout and/or stderr redirected to a file or another process, and may have its stdin read from a file or another process, instead of from some user having to type things in manually.
When a console program terminates, control is given back to its parent process. If it is run from a console as it should, you will still be able to see your output, because only your process died, not the shell that launched it. If you try and run it from the graphical shell, however, Windows does some odd things... namely, it's going to create a console window for you, temporarily, and then destroy that window when your program terminates.
You may think "well, it's okay to do this, because I want to run it like that." To which I say, fuck you, you're going to break someone's autograder. If you're doing this for a class at all, chances are your professor is going to have a script that compiles your program and runs it through a number of tests. Your program may be launched multiple times. It is expected that it will terminate.
If I were a professor, and a student used system("PAUSE") in a homework assignment, I would give them a 0 on the assignment.

I don't get it, I really fucking tried to learn linear algebra but I'm a horrible learner. Especially lots of theory. What are some good resources about linear algebra? Preferably something with lots of practical exercises and examples.
>>53658365
All of these questions on how to teach yourself <math subject> may be better directed at /sci/, which is much more focused on math than we are. I personally learned linear algebra and probability theory several years ago, in my undergraduate studies, and I don't think I have the book for it anymore. I don't know many people who teach themselves math outside of a university context (compared to a much larger amount of people who teach themselves how to program), but when they do, I think Khan Academy is one of the places they look in general.

return x;
}
void print(char* str)

}
int main(int argc, char** argv)
{
char* x = rtn_ptr();
print(x);
return 0
}
>>53659555
So basically my pointer was getting lost somehow when it was passed to the function?

x dies after you exit rtn_ptr.
You also don't need the \0 at the end of the string or the memset.
>>53659661
Ahh alright, I thought this might have been the case. It's basically getting blasted (or trampled) off the stack after the function returns yeah?

How to execute stuff in GPU by using OpenGL alone? Let's say I don't want to draw anything - just want to perform some simple calculations. How do I do that?
>>53656388
>Just to make sure, is it not possible to do that using while loop?
Anything is possible.
You can make it using goto (this is what the compiler actually does when it turns it into machine code)
You can use an infinite while loop with a shit ton of ugly if statements that check when to break it.
You can even write a recursive solution if you want (don't do this unless it's tail recursive)

too lazy to read your code, also dont fuck with c++. Look up array.map and array.reduce or whatever the equivalent array methods are in c++.

C# and .NET are open source now, ya dingus.
You can use C# + GTK# for some pretty good results.

if you're using C++ then abstract a matrix into rows/columns of vectors

then what do I fuck with?

Since no one has given you a serious answer let me be the first to offer one. Try to code a program that can find all Kaprekar Constants.

Ok, thank you.

Ah I didn't know that thanks!

This is an anime image board tho
>>53661224
so pretty much in the language i use map will iterate over the array and apply a function to every index, returning a new array. and reduce will take every index from 0 up and run them though a function one by one while saving the previous result until it has one value to return.

you could make your matrix be a 3-element array of 3-component vectors

Can I safely assume that my program can use 99% of the CPU on a constant basis for the purpose of determining minimal requirements?
at least most of the time you shouldn't really even have to left-pad strings on a website, just align them with html5+css or someshit, fucking cancer

not really
i'm using around 5-30% just idling with my shitty core 2 duo
Should I learn Common Lisp or Scheme?

>>53662187
Aww. Thank you. Do you have any idea what are the agreed conventions for determining minimal requirements in terms of CPU usage percentage?
>>53662223
don't know if there is any standard set, i think it's mainly just testing or estimating which hardware will be enough to provide a tolerable user experience for a typical use case
>>53662223
You can make a CPU get to 99% load easily, but there's no way to make sure your program is using that 99%.
If you could, any virus or malicious software would just wreck the CPU time to stop any other processes from detecting it.

Working on my file server with torrent support. Currently working on making my first HTML template. It's really nice that Go checks the template at compile time. The website is pure HTML and doesn't even use CSS for now and will never use JS.
Hopefully I'm able to release version 0.1 today.

I'm really glad you finally understand pointers anon. But you're retarded.

if a and b are pointers then b will still be 1

There's always code cleanup you can do or write documentation. That'll get you familiar with the Nim codebase.

Your analogy is flawed anyways.

i don't even use or like python but the complaint implied by >>53662603 is fucking retarded
>>53662936
Why is it a flawed analogy? Why do you think you'll be useful to the development of a programming language if you admit you know zilch about the subject?

Ive been looking into this a lot lately. Wikipedia says the fastest known algo for integer factorization is O(n^2), but its still unknown if there can be anything faster.
I have an idea, but the numbers they're testing are hundreds of bits long, way more than a 64 bit integer can store. How are these numbers even dealt with? How do you work with numbers bigger than 64 bits in high level languages?

First of all crunching prime numbers is normally SANELY only done in low level languages, using large number libraries.

Hey idiot here in need of help with c++.
Im reading in a bunch of numbers from one file into a 2D array in the first function.
How would I access the array I made in the first function, to use in a second function?
>>53664085
pass it as a parameter or store in a variable both functions have access to
>>53664085
pass by reference... probably// prototype
void stupidFunction(int arr[]);
int main(){
int arr[3][3];
stupidFunction(&arr[3][3]);
}
void stupidFunction(int arr[]){
// gay shit
}
Where can I meet a friendly and helpful community of Pascal programmers?
>>53664085
>>53664333
screwed that up, here's the right syntaxvoid stupidFunction(int (&arr)[3][3]);
int main(){
int arr[3][3];
stupidFunction(arr);
}
void stupidFunction(int (&arr)[3][3]){
// gay stuff
}
