1. Null pointers are easy to identify, but bad pointers can be sneaky .  Keenan Pepper 19 : 35, 25 May 2006 ( UTC)
2. Dereferencing the NULL pointer typically results in an attempted read or write from memory that is not mapped-triggering a segmentation fault or access violation.
3. This means that, for example, a pointer to 0 is never a valid pointer and can be used as a special null pointer value.
4. For safety, Swift introduced a system that helps address common programming errors like null pointers, and introduced syntactic sugar to avoid the structs and classes.
5. A null pointer in most programming languages means " no value ", while a null value in a relational database means " unknown value ".
6. C + + style : Exceptions are automatically generated when de-referencing a NULL pointer, accessing outside the bounds of an array, or running out of memory.
7. The not frequently used page-replacement algorithm generates fewer page faults than the least recently used page replacement algorithm when the page table contains null pointer values.
8. When the null pointer is dereferenced ( in most languages ) the program will immediately terminate there is no potential for data corruption or unpredictable behavior.
9. :: Nitpick : In my experience segfaults are more often caused by bad pointers ( e . g . to freed memory ) than by null pointers.
10. In C + +, while the NULL macro was inherited from C, the integer literal for zero has been traditionally preferred to represent a null pointer constant.
