Default copy constructor and assignment for class with move constructor and assignment

Question

Let\'s say I have this class:

class Test
{
public:
    Test();
};

AFAIK, compiler provides default copy constructor and assignment operator

Answer 1

According to section 12.8 Copying and moving class objects of the C++ Standard

7 If the class definition does not explicitly declare a copy constructor, one is declared implicitly. If the class definition declares a move constructor or move assignment operator, the implicitly declared copy constructor is defined as deleted; otherwise, it is defined as defaulted (8.4).

18 If the class definition does not explicitly declare a copy assignment operator, one is declared implicitly. If the class definition declares a move constructor or move assignment operator, the implicitly declared copy assignment operator is defined as deleted; otherwise, it is defined as defaulted (8.4).

So in your case and the copy constructor and the copy assignment operator are implicitly declared by the compiler but defined as deleted.
