WebHow to Define Copy Constructor for Struct in C++. You can define a copy constructor for a struct in C++ by implementing a special member function. The latter function usually will accept the reference to the struct object and returns the struct by value.

The move assignment operator is called whenever it is selected by overload resolution, e.g. when an object appears on the left-hand side of an assignment expression, where the right-hand side is an rvalue of the same or implicitly convertible type. Move assignment operators typically "steal" the resources ...
