    Code:
    class fred
      {
         char           * Buf;
         char const *& ConstBuf;
    
        fred ( void );
    
      };
    
    fred::fred(void)
    :
    Buf ( 0 ),
    ConstBuf ( Buf)
    {
    }
    ,

    1. Buffer and ConstBuf will refer to the same data storage area. ConstBuf read-only and Buffer read-write.
    2. I want the more restricted ConstBuf to refer to Buf. and declared in a class.
    3 Question: how do I initialize the reference? The compiler complains if I attempt to do so within a class, and it complains when I try to do so in a constructor.

    What advantage would that provide when you already have a pointer member?
