{
int s = 0;
int tmp;
for (tmp=n; tmp>0; tmp /= 10)
s += tmp % 10;
return (n%s == 0);
}
int main()
{
int hdno;
cout << "\n\n Check whether a number is Harshad Number or not: \n";
cout << " ---------------------------------------------------\n";
cout << " Input a number: ";
cin >> hdno;
if( chkHarshad(hdno))
cout << " The given number is a Harshad Number."<<endl;
else
cout << " The given number is not a Harshad Number."<<endl;
return 0;
}
