it's a never ending fight, there are enough use cases for C and personally I really like the language

Well i did like c more than c++ but because of OOP i should c++

msg * hello does not fit in your char[10] buffer, hence you overflow it

google for undefined behavior

it's worked. Strcpy did not give an error copying to the array

please learn about UB, worked does not mean correct

Good evening

please learn about UB, worked does not mean correct

Yes it's right

Good evening dima-chan

Yes it's right

your program might work but is not correct, the latest version of gcc even issues a warning. Search the internet for "buffer overflow" and "Undefined behavior" to see what's wrong.

Yes it's right

How would this snipet execute ? std::bitset<4> num(std::string("0100")); num.flip(2); num.flip(0); num.flip();

Any help on the dry run would be appreciated. Thanks

Do you know how to use a debugger?

Yes, But I didn't understand bitset functionality.

guys I have this task I'd like to automate and give a gui frontend to: basically I need to create a symlink to every folder in folder "B" and put it in folder "A". I also want to be able to remove or invalid the symlinks so they don't get loaded anymore by another program. would this better be some sort of powershell script or a full fledged windows c++ program?

Maybe C++ / C# program / Python script instead of shell script? All these shell languages are so weird

yes I agree

you are joking. shell is created for tasks like this. how are you going to create symlink on c++?

fact is that it would require making basically a file manager from scratch

this is overengineering

this is overengineering

but a gui frontend would be cool

I could share it with other people without too much explanation

would also be quicker to use

this is bad idea, cause your c++ code is harder to support, more bugs and so on

that's also true

create small shell script instead of big c++ project with classes :)

also yes, how do I make a symlink in C++?

i have 0 knowledge on this

learn, do all tasks using c++ not the best idea

also yes, how do I make a symlink in C++?

mmm

I will consider both options, thanks

yh Best coders use python at the time and c++ for the right job

happy I do not work with windows guys. hard to imagine someone will use c++ to check symlinks. this is small shell script

hello, guys! Can anyone give qtLog.dll file? one program on windows 10 requires.

A shell script should be enough, but do you really need GUI? 🤔

I found an uncompiled version, who can compile for me? https://sourceforge.net/projects/qtlog/files/qtlog/
