Array Sum using Pointers


#include <stdio.h>

int main() {
    int arr[100], n, sum = 0;

    printf("Enter the number of elements (max 100): ");
    scanf("%d", &n);

    printf("Enter elements of the array:\n");
    for (int i = 0; i < n; i++) {
        printf("Enter element %d: ", i + 1);
        scanf("%d", &arr[i]);
    }

    // Compute sum using pointers
    int *ptr = arr;
    for (int i = 0; i < n; i++) {
        sum += *ptr;
        ptr++;
    }

    printf("Sum of the array elements: %d\n", sum);

    return 0;
