Using Pointer to Pointer - C Programming

C Program to illustrate pointer to pointer concept.

/* C Program using pointer to pointer */

#include<stdio.h>

main ()

{

int a=22; /* Local definitions */

int *b; /* *b is a pointer variable */

int **c; /* **c is a pointer to another pointer */

b=&a; /* '&a' is a address variable */

c=&b;

printf ("\n Value of a is %d", a);

printf ("\n Value of a is %d", *(&a));

printf ("\n Value of a is %d", *b);

printf ("\n Value of a is %d", **c);

printf ("\n Value of b and address of a=%u", b);

printf("\n Value of c and address of b = %u", c);

printf ("\n Address of a=%u", &a);

printf ("\n Address of b=%u", &b);

printf ("\n Address of a=%u", *c);

printf ("\n Address of b=%u", &b);

printf ("\n Address of b=%u", c);

printf ("\n Address of c=%u", &c);

} /* main */

OUTPUT

Value of a is 22 Value of a=22

Value of b and address of a=2000

Value of c and address of b=4000

Address of a=2000 Address of b=4000

Address of b=4000 Address of c=6000
