If he smiles at you it means that he's a friendly person, He might know you like him (probably) so he passes you a smile, He might be developing a crush on you because your pretty, You should smile back or start a conversation. If he doesn't smile back then he sorta isn't interested.
Well. sometimes it can happen if he stares at you , and you look at him when he stares he might look away because he can be shy
I don't know if he likes you but he was probobly flirting with you:)

Smile!!!!:d You need to make them feel like that you like them because most of the time they are only looking at you like that because they have a thing for you and if you don't like them in that just go along with it otherwise you will hurt their feelings.
