As always a more long term solution to fretboard navigation is to see scales as INTERVAL shapes rather than note names - as these are universal to all scales, arpeggios and chords rather than specific to one particular root note - with this in mind the intervals for the C major scale are detailed below in the BAGED octaves manner:-
