I'm making a blackjack game and I have a pointer arrays for my dealer's and player's hand. The issue is that when I randomly generate cards to be stored in the array, they both have the same cards. Not sure if it is because they both point to the same address or something I haven't noticed.

The dealer cards should be different from the player cards but they are identical when you run the program.
