Pointer Types: Null Pointer, Wide Pointer, Void Pointer

174.5k

A void pointer is one that has no data type associated with it. A void pointer can be typecasted to any type and can hold any type of address.

A pointer is just a storage location for data in memory. The memory location is accessed using a pointer. There are several different sorts of pointers, including null pointers, wild pointers, void pointers, and others. Pointer arithmetic is the process of performing arithmetic operations on a pointer.

  • Null pointer.
  • Void pointer.
  • Wild pointer.
  • Dangling pointer.
  • Complex pointer.
  • Near pointer.
  • Far pointer.
  • Huge pointer.

NULL is a value that can be used with any type of pointer. It symbolises the lack of a value. A type is a void pointer. Because any pointer type can become a void pointer, it can point to any value.

A null pointer is a pointer that has no value. The null pointer can be used to: a) Initialize a pointer variable when it hasn't been assigned a valid memory address yet. b) When we don't wish to supply any valid memory address to a function argument, we can pass a null pointer.
