Overloading istream

[aab1990]

I need to overload the istream to take in rational numbers
Heres what I have,,,

istream& operator>>( istream& In, Rational& Item )
{
   char Ch;
   int Num, Den;

   In >> Num >> Ch;
   if (Ch != '/' or !In.good())
   {
      In.setstate( ios::failbit );
   }
   else
   {
      In >> Den;
   }
   Item.Numerator_ = Num;
   Item.Denominator_ = Den;

   return In;
} 

Here is the driver function that I am trying to run...

using namespace std;

#include 
#include 
#include 

#include "proj06.rational.h"

/*-----------------------------------------------------------------------------
  Name:  main

  Purpose:  Test some of the operations in type Rational
-----------------------------------------------------------------------------*/

int main()
{
   Rational A,B,C,D,E;
   ifstream Data;

   Data.open("proj06.tests", ios::in);

   Data >> A >> B >> C >> D >> E;

  cout << endl << "-----  Testing operator<<  -----" << endl;

  cout << "Rational A: " << A << endl;
  cout << "Rational B: " << B << endl;
  cout << "Rational C: " << C << endl;
  cout << "Rational D: " << D << endl;
  cout << "Rational E: " << E << endl;

The proj06.tests is pretty simple it looks like this
1/2
3/4
5/2
1/8
9/12
2/3
4/8
5/9
