// Access Array Elements using Pointer Arithmetic
#include <stdio.h>

int main() {
    // Step 1: Declare and initialize an array
    int numbers[] = {100, 200, 300, 400, 500};
    int size = sizeof(numbers) / sizeof(numbers[0]);

    // Step 2: Declare a pointer and point it to the first element of the array
    int *ptr = numbers; // 'numbers' is equivalent to &numbers[0]

    // Step 3: Access elements using pointer arithmetic
    printf("Accessing elements using pointer arithmetic:\n");
    for (int i = 0; i < size; i++) {
        printf("Element at index %d: %d\n", i, *(ptr + i));
    }

    return 0;
