Print Sum of Even Numbers

Code

#include <stdio.h>

int sum_even_numbers(int *ptr, int n) {
    int sum = 0 ;
    for(int i =0 ;i<n;i++)
    {  
        //checking for even number
        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;
}
