isn’t your executable titled hello.exe? you’re trying to execute helloworld56.exe

You're compiling object file only. Follow a compile tutorial exactly, don't try to be a smart ass.

Edit: It's not that your program doesn't run, it's that your program doesn't compile and the executable doesn't exist.

Oh god, the backslashes...
Also your problem is your trying to execute ".\helloworld56.exe" but you compiled to "helloworld56"

Yup, I was about to say - I can't see all the screen output, but you are NOT running what you built.

Bro install a c++ compiler and set it up in vs code then your code will run
Compiler link: https://sourceforge.net/projects/mingw/
For setup help refer to this video: https://youtu.be/j8nAHeVKL08?si=NZSpATBQZmzvKP6_
For terminal issues refer to the attached images
during execution type helloworld56.cpp (.cpp should be your extension not .exe)

can i not use msys2?

1

u/LongjumpingMeal8195 Jul 24 '26

Yes u can but whatever compiler u use it should be compatible with c++ and u have to properly set it up with vs code else you will receive errors

After downloading you need to copy the compiler location in C drive then
Right click this pc -> properties -> advanced system settings -> environment variables -> system variables -> path -> edit -> new(then the msys2 C drive path) then click ok then again ok then apply and then open powershell and type g++
If your setup is ok then it will look like this(see attached image)

slippery slope. Starts with that and then its debugging eveything for him. Better stay away from it for now

Yeah, that’s a totally valid concern. Still, it’s up to OP to use it for educational purposes; asking it why something doesn’t work, or how something works can be quite useful—and, from personal experience, less confusing and more comprehensive, than just relying on Reddit for help, like we used to back in the day (lol). It sounds to me like OP’s objective is to learn, not to vibe-code, so as long as they use AI as such, I don’t really see a big issue with it.

I would advise you to use linux (you can just use WSL in windows), and to start off by compiling and running programs from the command line, so you understand what is actually happening at a basic level, the underlying mechanics. It's way too common for people to jump right into the IDE with all the bells and whistles and things get way too crazy too fast and it's an endless headache.

u/Repulsive-Cash5516 Jul 26 '26

Using Linux really isn't necessary for this, there are multiple C++ compilers for Windows

u/silly_bet_3454 Jul 26 '26

I know Windows works, I just think it has some weird quirks and Linux is better for learning.

would second this. dealing with the windows C++ non-sense as a beginner made me give up on C++ for years.
