Answer 1

The main issue is that "YOU DIDN'T save YOUR FILE", first save your cpp file then enter the command (g++ file.cpp) or run it. Usually, this error occurs when file was not saved.

so click anywhere on your file and press ctrl+s to save it again, NOW YOUR ERROR GOT FIXXED, ......................
