What do you guys think about GTK for UI?

Also good

Hey can we have any condition when map<string,SomeStruct> on clear or ~() gave segfault SomeStruct{string,int,int} I am getting SEGSEV on exit of program, and don't even know what's happening and how to debug that

I've never used GTK so I can't say more I think it's also a good choice Qt is also because of Feature Integration in QtCreator IDE which makes UI development much easier It also allows styling with CSS which makes the UI more fluid.😎😎

So, any adoption in the wild?

Hey guys, I'm planning to create a terminal-based messenger focused in privacy and anonymity using C. Can you share your thoughts if it's feasible to make this entirely in C? I'm thinking of using XMPP protocol and TLS encryption for direct user connections. Any similar projects or potential challenges I should be aware of?

My suggestion: don’t use C unless you have plenty of time

I do have a plenty of time, but if this application should have some weird ass challenge im open to use something (maybe Rust?) to make my like easier

yeah, this surely is possible in c. I think libpurple is in C also cimpletley (pdigin) this could give you an example implementation. Im my experience Rust even adds to initial development time, it reduces maintainance time most likely though. I think C is a perfectly fine choice for this task. For SSL there is the openSSL library. I like wolfssl (small for static linking) and LibreSSL also. These libraries should be used to handle all socket creation. From what I saw using raw posix sockets almost always led to unwanted "features". not too familiar with the XMPP protocol, but im sure you can find a specification online. First try to think about the structure of you application very in depth. And try to get a pure tcp chat working first, then add ssl, and then go through the specification of XMPP. (maybe read through it before you start also, so there are no surprizes)

Writing applications in C is a nightmare

what do you write in?

I honestly don't know modern C, so its hard to compare, but in the past namespaces and classes where things i was missing in ANSI C to structure code better. But honestly, I love C++, but the mere amount of features in the language makes it hard to enforce code guidelines on a larger project and makes it therefore again harder to maintain. Mhmm at the end i think it is 99% preference as long as its not asm. If you say asm or haskell, you might need to reconsider your language choice... anything else for regular console applications should be good 😅

Use something to check code style. like clang-tidy

clang tidy is really cool though. You can even have automatic fixes and you can be very specific to what you want. Really appreciated tool! (your code needs to compile with clang though)

ok

#include <iostream> using namespace std; void calculateStats(int a, int b, int c, int& sum, int& product, float& average) { sum = a + b + c; product = a * b * c; average = static_cast<float>(sum) / 3.0; } int main() { int num1, num2, num3, sum, product; float average; cout << "Enter three nmbers here..: "; cin >> num1 >> num2 >> num3; calculateStats(num1, num2, num3, sum, product, average); cout << "Sum: " << sum << endl; cout << "Product: " << product << endl; cout << "Average: " << average << endl; return 0; }

we can only write return; (yeah, just return) to exit the function

does anyone want to test it? ;D

it`s a leetcode problem, and i can`t understand, why i can`t use "size".

what do you mean by "SHA256 Encryption" ?

the host and port are encrypted using the SHA256 algorithm. this is just a simple example that I wrote in a few hours; D

No, bro. you don't understand me. here's a piece of code for you and I'll try to explain: std::vector<std::shared_ptr<tcp::socket>> sockets; std::unordered_map<std::string, std::shared_ptr<tcp::socket>> data;. all connected sockets are stored in sockets, and data is stored in the socket and its hashed IP:port, and what do you mean, I'm working on it to make encryption for the entire network for secure communication))))))

Got it, you use hash to divide user?

i said i wrote it +- in 2 hours ))))) dont hate me

madhu bro ... i dont encrypt whole network using SHA256. The program is simple chat-server. User can start the server and connect to it. Server can accept many connections so each nodes(users) can communicate and synchronise the chat . so when someone is connected to server, each users get its host and ports in the form of sha256 hash. By this hash users can send private message for the recipient only(only the recipient will see the message) ....

Hi I’m working on a DFS algorithm on a graph. But I don’t know how to mark the wrong nodes which the program start to traverse from them an ends in a wrong answer. Any idea how to solve it ?

The correct term then is hashing. You hash the IP and port and index into a map using them to retrieve the socket details. Since you used the term encryption, it ended up confusing others about what you were trying to do.

Is there any reference for dos and don’ts on C/C++? Like what does the static analysis tools do to make sure all the potential threats are identified. Any book or reference will be helpful

int y=3^2^2*5/2+3; cout<<y; i got 9 answer why?
