(Computer science) pointer
A pointer is a special kind of variable that contains a memory address. Careful manipulation of pointers is essential in low-level languages like assembly and C. When using an unitialized pointer, this will result in an access violation. Pointers are useful for creating complex data structures such as lists, graphs and trees because they allow dynamic allocation of memory and manipulation of memory without knowing exactly where memory was allocated.Language specific links
