Concatenating C++ iterator ranges into a const vector member variable at construction time

Question

I have a class X, which I provide a snippet of here:

class X {
  public:
    template 
    X(Iter begin, Iter end) : mVec(begin, end) {}         


        

Answer 1

It would probably be best to drop const (why would you insist on it anyway?).

Otherwise, you have to build a concatenating iterator. It is quite a lot of code, see this thread for more.
