Nice blackjack game.
One question though, how do you quit, other than losing all of your money (or ctrl-c) that is?
A pause would be very useful if someone wanted to watch what was going on. Maybe you could use time.h to work something out.
Also, I think it might look better if the players where in a row, instead of a column. Such as
Code:
User AI AI AI Dealer
Hand Hand Hand Hand Hand
But that's just an opinion. It's a good game overall. Good work.
Oh, are you planning on adding anything too it? Like being able to split, double down, or buy insurance?
