  PROBLEM: ajackson@keck.tamu.edu (Andrew J. Jackson)
  
  I'm inquiring on how to declare a reference to an array of integers
  
  
  RESPONS: Efim Birger (efim@microware.com)
  
  try this:
  
  typedef int *intp;
  int arr[10];
  intp& aaa = arr;
  
  
  RESPONSE: fjh@munta.cs.mu.OZ.AU (Fergus Henderson), 11 Aug 94
  
  This code is illegal. `aaa' is a (non-const) reference to a pointer to int.
  `arr' is an array of int, which will be converted to a pointer to int.
  The result of that conversion is a temporary.
  You are initializing a non-const reference with a temporary, which is illegal.

  There is no sUCh thing as a reference to an array.
  
  
  RESPONSE: fjh@munta.cs.mu.OZ.AU (Fergus Henderson)
  
  There most certainly is.
  (An array of references is illegal, but a reference to an array is quite OK.)
