Here's what i have so far... I have yet to figure out how i'm going to handle the 11 / 1 situation with an ace, and when the player chooses an option for hit/stand, i get segfault.

HELP!!!

}dealerHand;

          "ten", "jack","queen", "king","ace"};

void printDeck(){
    int i;
    for(i=0;i<DECKSIZE;i++){
        printf("%s of %s value = %d\n ",cards[i].name,cards[i].suit,cards[i].value);
        if((i+1)%13==0 && i!=0) printf("-------------------\n\n");
    }
}

    srand(time(NULL));
