Assignment operator with reference members

Question

Is this a valid way to create an assignment operator with members that are references?

#include 

struct A
{
    int &ref;
    A(int &Ref)         


        

Answer 1

What you do is correct, but it is not very exception safe way of writing an copy assignment operator. Also, You should consider using a pointer member rather than an reference member.

You should implement it using the Copy and Swap Idiom. It has atleast 3 advantages over your implementation.
