c1083 :Cannot open include file: 'stdafx.h': No such file or directory [closed]

edit

Hi everyone, i tried running a code on Visual Studio using OpenCV and faced a few errors. These are common ones and i spent hours finding them online and troubleshooting, but couldnt find the right fix. I hope you guys could help me out with some insights for me to get going. Thanks guys!

below are the errors

Error C1083 Cannot open include file: 'stdafx.h': No such file or directory Error (active) E1696 cannot open source file "stdafx.h"

and these are the codes. Thank you everyone!
