    Type traits (since C++11) Type traits defines a compile-time template-based interface to query or modify the properties of types. Attempting to specialize a template defined in the <type_traits> header results in undefined behavior, except that std::common_type may be specialized as described in its description.. A template defined in the <type_traits> header may be instantiated with an ...NULL: implementation-defined null pointer constant, …
