OBD-II PIDs (On-board diagnostics Parameter IDs) are codes used to request data from a vehicle, used as a diagnostic tool.. SAE standard J1979 defines many OBD-II PIDs. All on-road vehicles and trucks sold in North America are required to support a subset of these codes, primarily for state mandated emissions inspections.
For C and C++, the compiler is allowed to give a compile-time diagnostic in these cases, but is not required to: the implementation will be considered correct whatever it does in such cases, analogous to don't-care terms in digital logic. It is the responsibility of the programmer to write code that never invokes undefined behavior, although ...
Dangling pointers can appear in certain computer programming languages, e.g. C, C++ and assembly languages. A tombstone is a structure that acts as an intermediary between a pointer and its target, often heap-dynamic data in memory. The pointer – sometimes called the handle – points only at
Null pointer dereference – A null pointer dereference will often cause an exception or program termination in most environments, but can cause corruption in operating system kernels or systems without memory protection or when use of the null pointer involves a large or negative offset.
IP Pascal implements the language "Pascaline" (named after Blaise Pascal's calculator), which is a highly extended superset of ISO 7185 Pascal. It adds modularity with namespace control, including the parallel tasking monitor concept, dynamic arrays, overloads and overrides, objects, and a host of other minor extensions to the language.

If the required size is not known until run-time (for example, if data of arbitrary size is being read from the user or from a disk file), then using fixed-size data objects is inadequate. The lifetime of allocated memory can also cause concern. Neither static- nor automatic-duration memory is adequate for all situations.
Downing Street and the Foreign Office are preparing to offer the incoming U.S. president an invitation once he is back in the White House, the report said, without citing specific sourcing. The ...
