You have a double "" in the line 2.
Also, rename your file into “hello.cpp”.

Given the error messages you get, it seems your file /home/lovish/hello.cpp (the one you are running) is wrong and does not correspond to the file hello.cpp you are showing here. The file you show is in ~/Desktop .

hello sir can you please explain more about what is wrong and tell me the steps on how to remove this error (as you can already see my level of coding in the above pictures aswell)

You are not running the .cpp file you are editing. Try:

$ cd ~/Desktop
$ root hello.cpp

Thank You so much Sir
