Data type which is used by swap function in sort algorithm must be MoveAssignable, then you can perform operation like below. CakeType c1, c2; c1 = move (c2); // <- move c2 to c1. But in your case CakeType has const data members. You can assign values to const data members only in constructors. WebThere is nothing you can do about it as you haven't seen the backend but what the hell!! Just use std::max.
