using namespace std;
int main()
{
int n,first,last;
cout << "\n\n Find the first and last digit of a number:\n";
cout << "-----------------------------------------------\n";
cout << " Input any number: ";
cin >> n;
first = n;
last=n % 10;
for(first=n;first>=10;first=first/10);
cout<<" The first digit of "<<n<<" is: "<<first<<endl;
cout<<" The last digit of "<<n<<" is: "<<last<<endl;
}
