Print Sum of Even Numbers

Code

#include <stdio.h>

bool is_even(int num) {
    return (num & 1) == 0;
}

int sum_even_numbers(int *ptr, int n) {
    // Your logic here
    
    int sum = 0;
    for (int i = 0; i < n; i++) {
        if (is_even(*(ptr + i))) sum += (*(ptr + i));
    }
    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;
}
