Usage

  • In the template parameter list of a template declaration, typename can be used as an alternative to class to declare type template parameters and template template parameters(since C++17).
  • Inside a declaration or a definition of a template, typename can be used to declare that a dependent qualified name is a type.
  • Inside a declaration or a definition of a template, (until C++11)typename can be used before a non-dependent qualified type name. It has no effect in this case.
