[Solved] That’s odd... problem (Code Coach)

Question

Could you please take a look at my code, i believe it should work but the SoloLearn app says it otherwise.

#include <stdio.h>
#include <stdlib.h>

int main() {

int len, i;
int sum = 0;
int *arr;
scanf("%d", &len);
arr = (int*) malloc(len * sizeof(int));
for(i=0; i < len; i++)
{
scanf("%d", arr+i);
if(*(arr+i)%2 == 0){
sum += *(arr+1);
}
}
printf("%d", sum);

free(arr);
return 0;
}

Thank you!

Answer 1

It should be
sum += *(arr+i);

Answer 2

Ok, it seems i am blind. Thank you very much! :)
