Can you finish it? :)

 #include <iostream>
#include <string>
#include <climits>

using namespace std;

//Optional function: depends on IDE. void wait_for_enter();

//Additional helper. void reset_istream();

//The model.
string Words[]={"null" ,"one", "two"};

{
   double theAmount;

   double theDollars;
   double theCents;
   theCents=modf(theAmount, &theDollars)*100;
   
   cout<<theDollars<<" "<<theCents<<endl;
   
   cout<<Words[(unsigned)theDollars]<<" : "<<Words[(unsigned)theCents]<<endl;

   reset_istream();
   wait_for_enter();
   return 0;
}

//--------------------------------------------------- void reset_istream()
{
   if(cin.eof())
   {
      cin.clear();
   }
   else
   {
      cin.clear();
      cin.ignore(numeric_limits<streamsize>::max(), '\n');
   }
}

//--------------------------------------------------- void wait_for_enter()
{
  cout << "press <enter> to continue...";
  // Reset failstate, just in case.
  cin.clear();
  string line;
  getline( cin, line);
}

The cool thing about this is that you can do it in a million ways. See if you like to study std::map and std::pair.
