* Unused variables. * Missing newlines at ends of #included files. * signed int loop variables where the termination condition is an unsigned 'get number of' function. * 'NULL' used inappropriately for an integer or character constant (NULL is a pointer) * abstract base classes with no virtual destructor. * Floating point constants used to initialise integer variables.
