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

Another solution is to use the reference_wrapper class ( in functional header ) :

struct A
{
    A(int& a) : a_(a) {}
    A(const A& a) : a_(a.a_) {}

    A& operator=(const A& a)
    {
        a_ = a.a_;
        return *this;
    }

    void inc() const
    {
        ++a_;
    }

    std::reference_wrappera_;

};
