C Program to Access Array Elements Using Pointer

In this example, you will learn to access elements of an array using a pointer.

To understand this example, you should have the knowledge of the following C programming topics:

Access Array Elements Using Pointers

#include <stdio.h>
int main() {
    int data[5];

    printf("Enter elements: ");
    for (int i = 0; i < 5; ++i)
        scanf("%d", data + i);

    printf("You entered: \n");
    for (int i = 0; i < 5; ++i)
        printf("%d\n", *(data + i));
    return 0;
}

Output

Enter elements: 1
2
3
5
4
You entered: 
1
2
3
5
4

In this program, the elements are stored in the integer array data[].

Then, the elements of the array are accessed using the pointer notation. By the way,

  • data[0] is equivalent to *data and &data[0] is equivalent to data
  • data[1] is equivalent to *(data + 1) and &data[1] is equivalent to data + 1
  • data[2] is equivalent to *(data + 2) and &data[2] is equivalent to data + 1
  • ...
  • data[i] is equivalent to *(data + i) and &data[i] is equivalent to data + i
