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++)
   {
    if(!((*ptr)&1)) //(*ptr) & 1 is a logic which is used to identify odd number, since we want even numbers.Hence performing not operation on it which will satisfy only for even numbers.
     sum=sum+(*ptr);
     ptr++;
   }
    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;
}
