Coping gear is not generated if there is an operation displacement.

Displacement? What? Displacement design or transferor? That's a few points in the answer.

And let's say we have a displacement operation, but we made it private. The copying award is not generated. What if we do, instead of private, delete (c++11)?

How many minimum methods should be declared deleted to prohibit any appropriations/copulation? Four?

Two: copy design and copying operator. If a separate movement is to be authorized, a moving designer and a transferee must be identified or declared as default♪

In this case, the following conditions for the designer shall not be fulfilled ( http://en.cppreference.com/w/cpp/language/move_constructor

• there are no user-declared copy constructors
• there are no user-declared copy assignment operators

A for the transfer operator of the assignment http://en.cppreference.com/w/cpp/language/move_assignment

• there are no user-declared copy constructors
• there are no user-declared copy assignment operators

I mean, at least they just removed it, but they did. So it's fair.

Well, for dessert, the copy designer and the copying operator:
