singly linked chain printing c++

Question

I am trying to pick my chain in the format {1,2,3,4,etc}. You can find the header file below which will have the layout of the nodes. I am just confused on how I should go about

Answer 1

It's hard to get your question. If you want to print the array to screen you should consider writing a display() like:

#include 
#include 
void Set::display() const {
   ostream_iterator out_it (cout," ");
   copy(Pool,Pool+Num,out_it);   
   cout << endl;
}

or if you want to write to a ostream& (as it is pointed out in the answer by @alestanis)

#include 
#include 
void Set::display(ostream &out) const {
   ostream_iterator out_it (out," ");
   copy(Pool,Pool+Num,out_it);   
   out << endl;
}
