References and arrays

发表日期：2008-3-8

　　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.

RESPONSE: admin@rzaix13.uni-hamburg.de (Bernd Eggink)

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.)
