I am reading ROOT Primer from official cite.
In paragraph ROOT as function plotter slits.C macro is used , when I try to type
root slits.C in the shell, it says no such file found
Warning in TApplication::GetOptions: macro slits.C not found
root: unrecognized option ‘slits.C’
Try ‘root --help’ for more information.
On the same page, a link to the github with the macros used in this tutorial was attached, I found the necessary file, but I don’t know where to save it so that ROOT finds it
