rule.

c++11 class default operator

• Default Constructor :: Exist on No Constructors.
• Copy Constructors :: Exist on No Move operators.
• Copy Assignment :: Exist on No Move operators.
• Move Constructors :: Exist on No Copy/Move operators & Destructors.
• Move Assignment :: Exist on No Copy/Move operators & Destructors.
• Destructors :: Basically noexcept. Virtual if parents have virtual Destructors.

# if there is a template member funtion, like template<class T> CLASS(const T&); still default operators are exist. like CLASS(const CLASS&);.

• move should be noexcept. In class parents and member sould have move too

values

• lvalue :: identity (이름) 을 가지고 있으며, move 될 수 없음.
• xvalue :: identity (이름) 을 가지고 있으며, move 될 수 있음.
• prvalue :: identity (이름) 이 없고, move 될 수 있음.

• rvalue :: prvalue | xvalue moveable
• glvalue :: lvalue | xvalue has_identity

비표준

• Rule of 3 :: Copy Constructors & Copy Assignment & Destructors are set. Because one of these means resource management.
