C++11 move constructor

Question

What would be the correct way to implement a move constructor considering the following class:

class C {
public:
    C();
    C(C&& c);
private         


        

Answer 1

There is no need to implement a move constructor here since you don't have to manually manage memory. Move constructors are only useful when you manually use dynamic arrays in your class.

You can still explicitly have the compiler create the default move constructor even though it should have already been done even if you don't request it:

C(C&& c) = default;
