In addition to overloading constructors with different parameters, we can overload constructors with default parameter values, as well. For example: class Circle {private:double radius;public:Circle() {radius =
The compiler chooses a move constructor when the object is initialized by another object of the same type, if the other object is about to be destroyed and no longer needs its resources. The following example shows one case when a move constructor is selected by overload resolution. In the ...
(For more information, see Overloading.) The argument-declaration-list may be empty. C++ defines two special kinds of constructors, default and copy constructors, described in the following table. Default and Copy Constructors 展开表 Kind of ConstructionArgumentsPurpose Default constructor Can be...

The following example shows one case when a move constructor is selected by overload resolution. In the constructor that calls get_Box(), the returned value is an xvalue (eXpiring value). It's not assigned to any variable and is therefore about to go out of scope. To provide motivation ...
