Passing variables by reference and construct new objects

Question

Hello there i have code like this one below and i don\'t know why it doesn\'t work.

class Clazz2;
class Clazz
{
    public:
    void smth(Clazz2& c)
    {

          


        

Answer 1

This is because non-constant references are not allowed to bind to temporary objects. References to const, on the other hand, can bind to temporary objects (see 8.3.5/5 of the C++11 Standard).
