dereferencing a pointer that points to nothing
Dereferencing a pointer that points to nothing refers to the act of accessing the value or data stored at the memory address pointed by a null or uninitialized pointer. It means trying to retrieve information from a pointer that doesn't point to a valid memory location, which can lead to unexpected behavior or program crashes.
