In this tutorial we will be learning the way for accessing value and address of Pointer. We can access the value of pointer using the de-reference operator and address of variable can be printed using address operator

Program : accessing value and address of Pointer

#include<stdio.h>
main() {
   int i = 3, *j, **k;
   j = &i;
   k = &j;
   printf("\nAddress of i = %u", &i);
   printf("\nAddress of i = %u", j);
   printf("\nAddress of i = %u", *k);
   printf("\nAddress of j = %u", &j);
   printf("\nAddress of j = %u", k);
   printf("\nAddress of k = %u", &k);
   printf("\nValue of j   = %u", j);
   printf("\nValue of k   = %u", k);
   printf("\nValue of i   = %d", i);
   printf("\nValue of i   = %d", *(&i));
   printf("\nValue of i   = %d", *j);
   printf("\nValue of i   = %d", **k);
}

Output :

Address of i = 65524
Address of i = 65524
Address of i = 65524
Address of j = 65522
Address of j = 65522
Address of k = 65520
Value of   j = 65524
Value of   k = 65522
Value of   i = 3
Value of   i = 3
Value of   i = 3
Value of   i = 3

Explanation

Consider the above diagram for accessing value and address of Pointer, It clear shows -
