understaning and passing arguments

[RicksteR]

okay, so iv tried to pass the argument, of allowing my array from main to work in my function buy_items()...the only thing is i must now enter something in, where i have stated "missing part of code here" iv tried a few things but they dnt work, So hopefully someone here knows?

#include <iostream>
#include <string>

using namespace std;

void buy_items(); // the missing part of the code is here, within the parenthesis right?

int main()
{   
    
    const int MAX_ITEMS = 10; 
    string player_inventory[MAX_ITEMS];
    
    int item;
    
    player_inventory[item++] = "shoe";
    
    cout << player_inventory;
    
    cout << "\n\nnow show the same array in a different function using arguments";
    
    buy_items();    //oh and also missing here too
    
    int pause;
    cin >> pause;
}


void buy_items(string player_inventory[], int item)
{
     
     cout << player_inventory;
     
     cout << "add extra item to the same array from main() and show it in this function";
     
     player_inventory[item++] = "hat";
    
     cout << player_inventory;
     

     
}

You have declared

string player_inventory[MAX_ITEMS];

in main() so the scope of this array is inside the main only.
If you want to use it in some other function then you need to pass to the function. First declare

void buy_items(string arr[]){
// do something withe array

}

then in the main call the function by passing the array as the argument

buy_items( player_inventory);
