Print Sum of Even Numbers

Code

#include <stdio.h>

int sum_even_numbers(int *ptr, int n) {
    int r=0;
    int i;
    for(i=0;i<n;i++)
    {
        if(ptr[i]%2==0)
        {
            r=r+(ptr[i]);
        }
    }
    // Your logic here
    return r;
}

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;
}
