Displaying the Value of a Returned Reference

After creating inventory, a vector of items, I display the first item through a returned reference.

cout << refToElement(inventory, 0) << "\n\n";

The preceding code calls refToElement(), which returns a reference to the element at position 0 of inventory and then sends that reference to cout. As a result, sword is displayed.
