Explanation / Answer

You can't pass int[] as a parameter man. This is not Java. Instead, you have to pass it as a pointer. i.e: void initializeDeck(int*) all your method headers will have to have parameters (int *deck) and all your function calls do not need (deck[DECK_SIZE]), but rather just (deck) After all of that, your program does not crash. Now there are just a few more things you have to deal with like the total not resetting after every game and some cards not being displayed. Here's your program that does not crash upon running. Good luck: //--------------------------------------------------------------------------------------------- #include #include #include #include #define DECK_SIZE 53 #define SPADES 6 #define HEARTS 3 #define DIAMONDS 4 #define CLUBS 5 #define PEANUTS 10 void rules (); void mainMenu(); void initializeDeck(int*); int RandomNumber (int,int); void Shuffle(int*); void swap (int*,int,int); void displayCard(int); int scoreCard(int); int dealer (int*); void checkDeck(int*); void gamePlay(); int main() { mainMenu(); } void mainMenu() // Function for asking player if they want to continue { int choice; system("cls"); printf(" Enter 1 to play Blackjack."); printf(" Enter 2 to See the Rules."); printf(" Enter 3 to Exit Game."); printf(" Choice: "); scanf("%d", &choice); // Prompts user for choice if((choice3)) // If invalid choice entered { printf(" Incorrect Choice.
