Explicit keyword on multi-arg constructor?

Question

I recently came across some weird looking class that had three constructors:

class Class
{
    public:
        explicit Class(int );

        Class(AnotherCl         


        

Answer 1

In C++11 multi-parameter constructors can be implicitly converted to with brace initialization.

However, before C++11 explicit only applied to single-argument constructors. For multiple-argument constructors, it was ignored and had no effect.
