i wanted to see the blueprint of how the first person example is but its not there when i see i click on blueprint, im very new to this and it must be one hidden button so help me out guys 
You would’ve gave little bit more details i guess. But anyway, check Blueprint tutorials first, it does not looks like you did.
You can see the blueprints that exists, but since the game is written in c++ you’re not very likely to find that much info there
