Program will allow anywhere between 1 and 6 players (inclusive). Here is what your output will look like:
Enter number of players: 2 Player 1: 7S 5D - 12 points Player 2: 4H JC - 14 points Dealer: 10D Player 1, do you want to hit? [y / n]: y Player 1: 7S 5D 8H - 20 points Player 1, do you want to hit? [y / n]: n Player 2, do you want to hit? [y / n]: y Player 2: 4H JC 9S - 23 points Dealer: 10D 9C - 19 points Player 1 wins Player 2 loses
Here are some special cases to consider. If the Dealer goes over 21, all players who are still standing win. But the players that are not standing have already lost. If the Dealer does not go over 21 but stands on say 19 points then all players having points greater than 19 win. All players having points less than 19 lose. All players having points equal to 19 tie.
