Print Sum of Even Numbers

Code

    #include <stdio.h>

    int sum_even_numbers(int *ptr, int n) {
        // Your logic here
        int sum = 0;
        int *p = ptr + n - 1;
        while (p >= ptr){
            if (*p % 2 == 0){
                sum += *p;
            }
            p --;
        }

        return sum;
    }

    int main() {
        int n;
        scanf("%d", &n);

        int arr[100];
        for (int i = 0; i < n; i++) {
            scanf("%d", &arr[i]);
        }

        int result = sum_even_numbers(arr, n);

        printf("Sum = %d", result);

        return 0;
    }
