Hi alls


I have read a list of pair of dates (x,fx) from a file and work with these.. 
  My program don´t found this file and no display the message
^File no found"  .  I don´t know what is happening.  Does somebody have one 
answer?
.

int main();
.
ifstream  f_in;
..
..
f_in.open("prova2.dat");

   if(f_in==NULL)
   {
    cout<<" Arquivo não encontrado";
       }

   f_in>> x >> fx;
   cout << x << fx;



f_in.close();

   system("PAUSE");
   return 0;
}
