question on class pointers.

I'm trying to make an inventory system for a rpg game, and I'm having a hard time doing it. This is the idea of what I have so far:

Code:

class Item
{
public:
void create_item(int amount){quantity += amount;}
string name;
int quantity;
} potion = {"Potion", 0}, antidote = {"Antidote", 0};

class Inventory
{
public:

string* name;
int* quantity;
}inventory[100];

void fill_inventory()
{
 inventory[0].name = &potion.name;
 inventory[0].quantity = &potion.quantity;
 inventory[1].name = &antidote.name;
 inventory[1].quantity = &antidote.quantity;
}

void display_inventory()
{
  for (int i = 0; i< 100; i++)
  if (*inventory[i].quantity > 0)
    cout << "Item# " << i+1 << " " << *inventory[i].name << " " << *inventory[i].quantity << endl;
}

So the idea is that each value in my inventory array points to an item name and quantity.
Then display_inventory() will show the user all of the items they "have" ( more than 0). To add an "item", all I would have to do is call that objects add function, and the Inventory pointers would "update" to show the correct quantity;

Is there a better way I can have the Inventory members point to their corresponding Item members? I wish I could just do inventory[0] = &potion; and the compiler would know to make inventory[0].name = &potion.name, and inventory[0].quantity = &potion.quantity

And my second question is: I'm going about this all wrong aren't I? Haha.

As you said yourself, make a class pointer. You seem not to need the Inventory class at all. Just an array of Item pointers

Code:

Item[100]* inventory;

is enough, isn't it?

Item[100]* inventory; //this line gets errors for me.
Item* inventory[100]; //this way works though, what's the difference?

I need each value in inventory[] to point to the name and quantity of an Item object;
I would like to be able to cout << *inventory[0].name << *inventory[0].quantity;
I'm just not sure how to accomplish that.

Edit:
Oh, so I can access object members and member functions through pointers. I just need to use '->' instead of '.'
