Different types of pointers in c language?

Answer 1

... are usable.

void pointer (generic pointer) : a special type of pointer which point to some data

of no specific types.

void *p;

null pointer : a special type of pointer which point nowhere.

it is usually used to check if a pointer is pointing to a null or free

the pointer during deallocation of memory in dynamic memory allocation;

it is define by using the predefine constant NULL

int *p=NULL;

wild pointer : uninitialized pointer. it hold a garbage value. i.e it is not pointing to

any memory location yet.

dangling pointer: pointer pointing to a destroyed variable.

it usually happen during dynamic memory allocation when the

object is destroyed but not free and the pointer is still pointing

to the destroy object.

Answer 2

Pointer is a variable that is used to store the memory address of another variable. There are differenr types of pointers: NULL pointer THIS pointer VOID pointer NEAR pointer HUGE pointer FAR pointer WILD pointer

Answer 3

Pointer variables and function pointers are the two primary types, as well as a void pointer (unknown type). Pointer variables can point to any valid type, including primitive types and user-defined types, as well as other pointer variables. Function pointers can point to any function with the same signature as the function pointer itself. Void pointers can point anywhere.

Answer 4

You can define pointers to every data-type (including elementary types, structures, unions, arrays and function), plus you can define generic pointers as 'void *'.

Answer 5

A pointer in C is a pointer. Examples:

int *intptr;

char *charptr;

int (*funptr)(int, char **);
