cannot open source file "iostream". Please run the 'Select IntelliSense Configuration...'

Question

This problem popped up out of nowhere in the middle of October.

" cannot open source file "iostream". Please run the 'Select IntelliSense Configuration...' command to locate your system headers.C/C++(1696) "

I'm getting this error in all of my files. I've tried uninstalling and reinstalling, changing the complier path, the Include path, and I've tried changing "c_cpp_properties.json" file, but nothing seems to work.

I am on a MacBook Air btw. The same problem happened on my PC, but I was able to fix that by following the instructions on the VSC website. But nothing seems to work for my Mac.

Can some one please help?
(I've included a simple code to show the problem)

(This is what my c_cpp_properties.json look like)

Hello @Justin C,

Thank you for taking time to post this issue in Microsoft Q&A forum.

As Visual Studio Code(VS Code is different from VS IDE) is currently not supported in the Microsoft Q&A forums, please kindly post your question on Github - vscode for better help.

Thanks again for your understanding.

Have a nice day,

Tianyu
