How to read an array in the C language?

There are two common methods in C language for reading an array by iterating through each element.

1. Traverse the array using a for loop.

#include <stdio.h>

int main() {
    int arr[5] = {1, 2, 3, 4, 5};
    int i;

    for (i = 0; i < 5; i++) {
        printf("%d ", arr[i]);
    }

    return 0;
}

1. Traverse the array using pointers.

#include <stdio.h>

int main() {
    int arr[5] = {1, 2, 3, 4, 5};
    int *ptr = arr;
    int i;

    for (i = 0; i < 5; i++) {
        printf("%d ", *ptr);
        ptr++;
    }

    return 0;
}

You can access elements in an array either by using the index or a pointer, regardless of the method used.
