Using Pointers and Arrays - C Programming

Write a C program to print the value and the address of the element using pointer.

* C Program to print the value and the address of the element using pointer */

#include <stdio.h>

main()

{

int arr[5]={10,20,30,40,50}; /* arr[5] has five elements of integer data type */

int i,*p_arr; /* i,*p_arr is a pointer variables */

p_arr=arr;

for(i=0; i<=5;i++)

{

printf("Address=%u", &arr[i]);

printf("Element=%d", &arr[i]);

printf("%d", *(arr+i));

printf("%d",p_arr[i]);

printf(“%d”, *(p_arr+i));

} /* for */

} /* main */

OUTPUT

Address 4000 Element 10 10 10 10

Address 4002 Element 20 20 20 20

Address 4004 Element 30 30 30 30

Address 4006 Element 40 40 40 40

Address 4008 Element 50 50 50 50

EXPLANATION: In the above program, the variable arr[] is declared as integer array, the elements are displayed using different syntax. (1) &arr[i], (2) *(arr+i), (3) p_ (4) *(p_arr+i).

1) &arr[i] ‒ This prints 0th address elements from the array.

2) *(arr+i) ‒ The arr+i is addition of a constant with the base address of an array. It shows the address of element. The *(arr+i) points to the elements of an array.

3) p_arr[i] ‒ Here 'p_arr' refers to the element number and i refers to the base address. By varying p_arr and i the various elements of the array are displayed.

4) *(p)arr+i) ‒ This statement is same as 2.
