null pointers
Null pointers are variables or pointers in a computer program that do not point to any valid memory location. They hold a special value, usually represented as "null" or "0", indicating the absence of a meaningful address. Accessing or dereferencing a null pointer can result in a program crash or unexpected behavior.
