vector erase iterator outside of range

[Dolichan]

customer->GetInventory().erase(customer->GetInventory().begin()+choice);

"customer" is a class.
"Inventory" is a class.
"GetInventory()" returns a vector<Inventory>.


It would be helpful if someone could explain to me why it returns a "vector erase iterator outside of range" error. Thank you in advance. :)

"GetInventory()" returns a vector<Inventory>.

Really? A copy, not a reference?

In that case this and that calls are returning copies of original. Different copies.

customer->GetInventory().erase(customer->GetInventory().begin()+choice);
//                    ↑ This                     That ↑ 

Return vector by reference.
