How to add bits/stdc++ in VS code

1. cmd + click on iostram or any header file it will open the file

2. Right click on the file it will open the context menu and click on Reveal on finder it will open the file in the location

03. On that location create a file name bits
(You might need to use your password to create the folder

04. Copy any file with *.h extension and paste it inside bits folder

05. Rename the file to stdc++.h

06. Right click Open it with VS code

07. Add this content inside the file

08. Save it and restart VS code

If you find any difficulty let me know. We will figure it out 😉
