Function Templates


  • Template functions define a family of functions for different template arguments.

  • When you pass template arguments, function templates are instantiated for these argument types.

  • You can explicitly qualify the template parameters.

  • You can overload function templates.

  • When you overload function templates, limit your changes to specifying template parameters explicitly.

  • Make sure you see all overloaded versions of function templates before you call them.
