TITLE: References and arrays


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.)
