C :

#include<stdio.h>
#include<string.h>
int main()
{char n[1000];while(scanf("%s",n) && n[0] != '0'){int i, s=0;for(i = 0; i < strlen(n); i++)s = (s * 10 + (n[i]- '0')) % 17;if(s==0)printf("1\n");else printf("0\n");}return 0;}

C++ :

#include<iostream>
#include<string>
using namespace std;
int main()
{
    string str;
    while(cin>>str && str!="0")
    {
        int i=0,tmp=0;
        while(i<str.size())
        {
            tmp=(tmp*10+(str[i]-'0'))%17;
            i++;
        }
        if(tmp%17==0)
            cout<<1<<endl;
        else
            cout<<0<<endl;
    }
}
