Correct Answer - Option 2 : Void pointer
Void pointer: It is a specific pointer type – void * – a pointer that points to some data location in storage, which doesn’t have any specific type. Void refers to the type.
- void pointers cannot be dereferenced. It can however be done using typecasting the void pointer

Pointer arithmetic is not possible on pointers of void due to lack of concrete value and thus size
Other Important Points
Dangling pointer: A pointer pointing to a memory location that has been deleted (or freed) is called dangling pointer.
Uninitialized pointer : An uninitialized pointer stores an undefined value. A null pointer stores a defined value, but one that is defined by the environment to not be a valid address for any member or object.
NULL Pointer : NULL Pointer is a pointer which is pointing to nothing. In case, if we don’t have address to be assigned to a pointer
