Can anybody explain why the following code works with BC5.0 and does not
work with DJGPP gcc version 2.7.2.1 ? The problem is that if the user
enters an EOF (CTRL Z in DOS) to stop the loop, the user is not prompted
to enter the double d ! Is this a bug or not. I can't find an explanation !

#include <iostream.h>
int main() {
  int i;
  while(cin >> i) cout << i << endl;  // CTRL Z to stop the loop
  cin.clear();                        // reset the flags    
  double d;
  cin >> d;                           // with DJGPP gcc, the user cannot
enter a value 
  cout << d << endl;
}

Many thanks

This is a DOS misfeature: the EOF condition for the console device is
not cleared until something is written to the console.

Output an empty string to the console device before calling cin.
