- Special member functions in C++ are functions which the compiler will automatically generate if they are used, but not declared explicitly by the programmer.The automatically generated special member functions are:
* Default constructor if no other constructor is explicitly declared.
* Copy constructor if no move constructor and move assignment operator are explicitly declared.If a destructor is declared generation of a copy constructor is deprecated (C++11, proposal N3242).
* Move constructor if no copy constructor, copy assignment operator, move assignment operator and destructor are explicitly declared.
* Copy assignment operator if no move constructor and move assignment operator are explicitly declared.If a destructor is declared, generation of a copy assignment operator is deprecated.
* Move assignment operator if no copy constructor, copy assignment operator, move constructor and destructor are explicitly declared.
* Destructor In these cases the compiler generated versions of these functions perform a memberwise operation. For example, the compiler generated destructor will destroy each sub-object (base class or member) of the object. The compiler generated functions will be public, non-virtual and the copy constructor and assignment operators will receive const& parameters (and not be of the alternative legal forms). (en)
