Accessing Structures Inside Structures

Hello,

As you can see below, the program will hold the account data in one structure and then the character data in another structure. Eventually, 'player_data' will contain more structures to other parts of the program (but that's not the case). For some reason I cannot access the 'player_data' structure through the 'account_data' structure.

This is what my current code looks like (for testing purposes).

Code:

int main(int argc, char *argv[])
{
    acc_data[0].player[0]->class_id = 10;
    
    printf("class id: %d\n", acc_data[0].player[0]->class_id);
  
    system("PAUSE");
    return 0;
}

And here's the structures.

Code:

struct account_data
{
    char user[NAME_LENGTH];
    char pass[NAME_LENGTH];

    struct player_data *player[MAX_CHARACTERS];

    char *buffer;
    char *incbuffer;

    short char_id;
    short char_num;
    short ingame;

    long attack_timer;
    long data_timer;
    long data_bytes;
    long data_packets;
    long party_player;

    short in_party;
    short target_type;
    short target;
    short casted_spell;
    short party_starter;
    short getting_map;
} acc_data[100];

struct player_data
{
    char name[NAME_LENGTH];

    short sex_id;
    short sprite_id;
    short class_id;
    short access_id;

    short level;
    long exp;
    short pk;
    short guild;

    long hp;
    long mp;
    long sp;

    short str;
    short def;
    short spd;
    short mgc;
    short pnts;

    short slot_armor;
    short slot_weapon;
    short slot_helmet;
    short slot_shield;

    int map_id;
    short coord_x;
    short coord_y;
    short dir;
};

What am I doing wrong, because every time I use printf, the program crashes? I want to constantly add, change, and remove data in certain situations.

EDIT: And is there a way to shorten a structure check using the array requested?

your player is just array of pointers

- or you should allocate the array using malloc
- or change it to array of structs
