Array of structs and new / delete

Question

I have a struct like this:

class Items 
{
private:
    struct item
    {
        unsigned int a, b, c;
    };
    item* items[MAX_ITEMS];
}

Answer 1

Setting items[5] to NULL doesn't delete the memory associated with the item, it simply sets the pointer to that item to NULL, therefore the memory is leaked.

You can delete the item by calling:

delete items[5];

Since C++ has not automatic garbage collection, you need to delete any memory you no longer need.
