      Description

      If a type is declared but not used, then it is unclear to a reviewer if the type is redundant or it has been left unused by mistake.

      Noncompliant Code Example

      void unusedtype()
{
  typedef int local_Type; // Noncompliant, unused
}

      • MISRA C++:2008, 0-1-5 - A project shall not contain unused type declarations.
