_>12.8.8.
_>The implicitly-defined copy constructor for class X performs a memberwise copy of its subobjects. The
_>order of copying is the same as the order of initialization of bases and members in a user-defined constructor
_>(see 12.6.2). Each subobject is copied in the manner appropriate to its type:
_>— if the subobject is of class type, the copy constructor for the class is used;
_>— if the subobject is an array, each element is copied, in the manner appropriate to the element type;
_>— if the subobject is of scalar type, the built-in assignment operator is used.
