#include errors detected in vscode

Question

I am using Visual Studio Code in my C++ project. I installed Microsoft C/C++ Extension for VS Code. I got the following error:

#include error

Answer 1

I ended up here after struggling for a while, but actually what I was missing was just:

If a #include file or one of its dependencies cannot be found, you can also click on the red squiggles under the include statements to view suggestions for how to update your configuration.
