I have a python script to bruteforce
How do i convert to c ++ bruteforce script?

you either:
- write it by hand
- convert it with some program
- ask some ML model to do it for you

you could also ask for the private key to the true owner of these 10k$
SHP
?
i didnot think about the time complexity, but it seems your while condition should be && rather than ||
SHP
and the inner if is unnecessary
SHP
and I think this method is too slow...you'll fail on hard cases

What is your approach?

#include <stdio.h>
size_t a() { return 100;}
int main()
{
long d = -1;
if ( d < a() ) {
printf("1\n");
} else {
printf("2\n");
}
}
Anyone guess what it prints?

I don’t think there is something about size_t idk about

I don’t think there is something about size_t idk about
that's exactly what this is about:
/tmp$ gcc test.c -Wall -Wextra
test.c: In function ‘main’:
test.c:6:13: warning: comparison of integer expressions of different signedness: ‘long int’ and ‘size_t’ {aka ‘long unsigned int’} [-Wsign-compare]
6 | if ( d < a() ) {
| ^
/tmp$ ./a.out

c++ is dangerous under this kind of problems

that's why you use show warnings
Like i expected smt like this but that just because it’s not the first time, a newbie would not even ask himself this kind of questions

The more I learn this le language the worst I feel

Operators < > <= >= could handle such issues, agree?

Int and uint comparisons

while (*str++) is basically while (*str++ != '\0')
I am new in c programming. But i have experience of programming.
Am I right, amn't?
Idea behind this is :-
Assignment or increment operation to pointer level
And it will be run until null character \0 don't comes .
\Device\NUL
You may wonder why -1 == uintmax_t
\Device\NUL
Because they're using same binary numbers
\Device\NUL
unsigned overflow and signed overflow are checked via CPUs itself, and not by C / C++. Afaik there's standard about overflow checking

For example there's SF and OF flag on x86

It points first then increment it

semantic sugar to array :P
Ashutosh Kumar
*str++ is *str; str++
I got it. Now i understand it incrementation to pointer.
Because i have read my book of c programming few days ago.

Hi, I need some advice.
I own a Microsoft Surface and I would like to write code on it. Unfortunately it's not a really powerful machine, and copmiling code on it takes time and draws a good amount of power.
To get around this issue I thought about sending the code (via Git or something else) from the Surface to my PC at home, compiling it there, and returning the exe (and all the extra stuff I might need) on my Surface to be executed.
Is this a good solution? Is there a better way? If this is a good approach, what's a "good setup" to make it work?

I guess some kind of remote access like TightVNC could work. And then you can automatize the process if you want.

Make your PC a linux machine and connect to it using ssh
You can even use VS Code with ssh to fo the remote development
Гулящий
Oh, good idea!
With VSCode you can ssh-connect to a windows machine too. As far as I know.

I just do not like Windows as development platform

how to validate a member id, name?

I was thinking about that but my internet connection is not that stable and I would also like the program to be executed on the Surface an not remotely on the PC

I have a surface and I have code block on it... I'm learning C on it for 8 months... All seems ok.

1. Sshfs + ssh
2. Emacs + tramp
3. Vscode + remote dev
4. Jetbrain + remote dev

Does 4 even work properly? Last time I tried it, it was garbage

I've seen people using it on our servers so I guess it does work

Can someone help me with small program on c++?
The given quadrant is a matrix (the size of the matrix can be arbitrary). Display the elements of the main and side diagonals on the screen. Reset the elements below the side and above the main diagonal (marked in gray on the diagram).

And what help you need? You only posted your assignment which is against the rules

I have the code ready, but it resets the wrong elements

Maybe you... Should have posted the code along with your message?

I also need to post it with photo to understand what elements needed to reset, but I can`t

It is not important, it teaches algoritms and performance ideas, but can also teach wrong things about programming (it shifts focus into things that are less important in writing real code, and not allows to execute some more important skills).
Pavel
So I would say, do it if it is fun for you. But if it's not fun for you, skip it and just write hobby projects instead.

Use a byte array on python side and on C++ side read it as an array of unsigned chars

Hi, everyone
I'm building a small side-project, and i want some opinions! This project should work as like some simpler version of Cargo from the forbidden language, but to C projects.
I had this idea cause i really dont like to configure all my projects from scratch and all, so i was thinking that would be cool to make a C tool that could do it for me (even knowing that i could probably do it using Bash) and implement some fancy flags and stuff like that, the project it's actually in a stage that is almost usable, but i want other persons opinions in what i can improve it or change, there is the link to the repo:
