How to write a program to calculate the sum of digits present on even and odd places?

int main()

{

    int n,r,count=1,es=0,os=0;

    printf("\n enter the number:");

    scanf("%d",&n);

    while(n!=0)

    {

        r=n%10;

        if(count%2==0)

            es=es+r;

        else

            os+=r;

        n=n/10;

        count++;

    }

    printf("\n sum of even=%d",es);

    printf("\n sum of odds=%d",os);

}

Output:

enter the number: 34567

 sum of even=10

 sum of odds=15
