Is a move constructor created by default?

Question

I know that a copy constructor is always created by default even if I don't explicitly create one. Is the same true for a move constructor? Let's assume a have a very simple class:

class SimpleClass
{

public:
    SimpleClass(int value) :
            member(value)
    {}

    int member;

};

Do I explicitly need to write SimpleClass(SimpleClass &&other) default to create the default move constructor or not?

Look at [conditions-for-automatic-generation-of-default-ctor-copy-ctor-and-default-assignment](http://stackoverflow.com/questions/4943958/conditions-for-automatic-generation-of-default-ctor-copy-ctor-and-default-assi) — Jarod42, Sep 29 '15 at 08:19
Watch out for Visual Studio versions prior to 2015 they did not create move constructor by default. — Chris Drew, Sep 29 '15 at 08:25

Like the copy constructor the move construction is available by default. Check the reference docu here

Except, that if you declare a copy constructor, destructor or assignment operator, move operations won't be generated. – Melkon Sep 29 '15 at 08:22
