I’m trying to make my program to have 3 shipment objects. I want shipment 1 and 2 to be data that the user entered. Shipment 3 I would like it to be the default values but for now I can ignore it since my shipment 2 fields aren’t being copied properly. When I run my code, I can see that shipment 1 is properly being outputted out but when I use output(shipment2); the fields aren’t being copied from shipment output(shipment);. To what I understand the copy constructor is being called but nothing is being copied? I can see it’s displaying my default values which is good but it’s just not being copied.
