What's wrong with this C++ code ? std::vector<const A &> is not ok but std::vector<const A *> is right

    class A{};
    A array[10];
    std::vector<const A &> fun(){
     std::vector<const A &> ret;
        for(int i=0;i<10;i++){
            ret.push_back(arr[i]);
        }
        return ret;
    }

You can't have a vector of references. – tkausl Sep 05 '17 at 05:40
You missed ']' here: ret.push_back(arr[i); – Asesh Sep 05 '17 at 05:40
That code shouldn't even compile – Asesh Sep 05 '17 at 05:40
A vector of std::reference_wrapper is allowable though. – Bathsheba Sep 05 '17 at 06:09
