C Programming accessing value and address of Pointer
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 -
Variable | Actual Value |
---|---|
Value of i | 3 |
Value of j | 65524 |
Value of k | 65522 |
Address of i | 65524 |
Address of j | 65522 |
Address of k | 65520 |
