string  GLOBAL_arrayInventory[0];
int     GLOBAL_intItemNumber            = 0;
void    addItem(string);

addItem(GLOBAL_tempNewItem);

// BEGIN ADD ITEM
void addItem(string tempNewItem){
    GLOBAL_arrayInventory[GLOBAL_intItemNumber] = tempNewItem;
    GLOBAL_intItemNumber += 1;
}
// END ADD ITEM


What's wrong with this function? I don't understand what's happening here. I'm getting:
0x7fff9067ebb3: movb (%r14), %cl Thread 1: EXC_BAD_ACCESS (code=1, address=0x10aba03f8)

I don't understand why I'm getting this error.

Well it seems you have declared an array of zero length (I'm confused as to why this is even legal, but whatever), and you are trying to access one of its elements. Since it has zero length it has no elements and attempting to accessing one results in the error you are getting.

unfortunately still got the same error.

I'm able to initialize another array in a similar way.

string  GLOBAL_arrayItems[0];

void    initArrayItems();

initArrayItems();

void initArrayItems(){
    GLOBAL_arrayItems[0] = "Hammer";
    GLOBAL_arrayItems[1] = "Sword";
    GLOBAL_arrayItems[2] = "Vasoline";
    GLOBAL_arrayItems[3] = "Bow";
    GLOBAL_arrayItems[4] = "+5 Health";
    GLOBAL_arrayItems[5] = "+10 Health";
    GLOBAL_arrayItems[6] = "Axe";
}

Now when I run an inventory check with more than one item in the inventory I get this:
1
2
3
 
Inventory:
+5 Health
h({\202x\377+5 HealthordVa

// BEGIN CHECK INVENTORY
void checkInventory(){
    int tempItemNumber  = 0;
    tempItemNumber = GLOBAL_intItemNumber;
    cout << "Inventory:" << endl;
    while(tempItemNumber > 0){
        cout << GLOBAL_arrayInventory[tempItemNumber] << endl;
        tempItemNumber -= 1;
    }
}
// END CHECK INVENTORY


I changed the initArrayItems back the way I originally had it, in the randomItemCreator, and it seems to be fine now. Aside from the issue I'm having above.

    srand(static_cast<int>(time(0)));
    randomItemSelector = 1 + rand() % (7 - 1 + 1);
    randomItemReturn = GLOBAL_arrayItems[randomItemSelector];
    
    return randomItemReturn;

// END RANDOM ITEM CREATOR


Thanks in advanced.
