EDIT: Literally 1 second after I pressed the post button I got an idea and thats what it was. Why does that always happen? xD
The solution was that my player_hand[] and dealer_hand[] arrays had a size of DECK_SIZE / 2, but I was initialising them to 0 from within the for loop where I was initialising the deck[] array (which has a size of DECK_SIZE), so the last 24 0s of one of those where overflowing into deck[]...
Hello everyone!
I am trying to make a simple blackjack (21) game in C, to practice some pointer stuff, and I am running into an issue with the function that initialises all my arrays. The way I am going about setting everything up, I have an integer array for a standard deck of 52 cards (values from 1 to 13, each 4 times), an integer array for the shuffled deck, and 2 more arrays for the player and dealer hands (irrelevant at this point as they are not used yet).
My issue is that after successfully initialising the deck array (the non-shuffled one) and outputting the values from within the for loop that sets them, I get what I expect to see which is:
1, 2, 3, ..., 13, 1, 2, 3, ..., 13, ... (so on for 52 cards).
But when I output each value from a different for loop in the same function, the first 24 elements (0-23) are 0s each time I run it. I can not figure out why that would be. I ran my program through valgrind which reported that there were no memory leaks.
Here is the relevant code:
#define DECK_SIZE 52
int initialise_decks(int* deck, int* shuffled_deck, int* player_hand, int* dealer_hand, int size)
{
printf("=================INITIALISING==================\n");
for (int i = 0; i < size; i++)
{
deck[i] = (i % 13) + 1;
player_hand[i] = 0;
dealer_hand[i] = 0;
printf("deck[%d]: %d\n", i, deck[i]);
}
printf("+++++++++++++++++++++++++++++++++++++++\n");
for (int i = 0; i < size; i++)
{
printf("deck[%d]: %d\n", i, deck[i]);
}
printf("+++++++++++++++++++++++++++++++++++++++\n");
return INITIALISE_DECKS_SUCCESS;
}
int main() {
srand(time(0));
int deck[DECK_SIZE];
int shuffled_deck[DECK_SIZE];
int player_hand[DECK_SIZE / 2];
int dealer_hand[DECK_SIZE / 2];
int initialise_status = initialise_decks(deck, shuffled_deck, player_hand, dealer_hand, DECK_SIZE);
if (initialise_status != INITIALISE_DECKS_SUCCESS)
{
return INITILIASE_DECKS_FAIL;
}
return PROCESS_EXIT_NORMAL;
}

Helldivers 2 is currently occupying my mind 24/7. Yes there are a few bugs here and there, but the game is just so good they don't really matter in terms of spoiling the experience. It is a 4 person co-op game and its really fun if you find a group of friends you can play with, or a good group of randoms who communicate. However, you can play solo, you just need to change up your playstyle for certain missions, like go a bit stealthier. Honestly try it, and if you want to try the group aspect of it join the official discord where there are lfg channels you can find people to play with.
