Print Sum of Even Numbers

Code

#include <stdio.h>
int sum_even_numbers(int *ptr, int n) 
{
    // Your logic here
    int sum;
    for(int i=0;i<n;i++)
    {
        if((*(ptr+i)%2)==0)
        {
            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;
}
