Run code configuration not showing up in VS Code

So, I wanted to run a program in c, but after installing code runner, I find the program running in output. I found the solution i.e. to go to run code configuration in settings. But I found that the run code configuration option is missing.
I tried a few things but all were in vain. Kindly help me please.

Is there a reason why my VScode CLI doesnt recognise standard commands?

I am inputing commands into my CLI to run my source code yet it doesn't recognise these standard commands. I have updated my includepath, that became effective as I noticed the squiggles no longer appeared under the text in my source code, but I am unable to run my code from the command terminal for some reason. For some context, I am using C language. My question please is what could be the reason why linux os refuses to understand simple commands such as ' g++ --version'? Any help would be appreciated, thanks.

WSL2 Jupyter Notebook error Powershell cannot find file specified

I am excited about the wsl2 and then straightaway installed Anaconda for setting up my DS environment.
Following this article
After I typed
jupyter notebook
I see this error.
Could anyone give some hints?
Found another article
It seems that this error is cause by missing of browser(GUI) in the WSL, so that is why this error happens.
I then run
jupyter notebook --no-browser
No it doesn't show the error.
Could someone confirm my guess?
