How do we make the 2 NetworkNodes neighbors of one another?
A. To make the 2 NetworkNodes neighbors of one another, you must pass each to the other’s add_neighbor(). Of course, add_neighbor() takes a pointer to a NetworkNode, so specifically, you must pass each’s “address”. • Q. In what order do we print out elements in the queue for the print() member function? A. Print from the front (where things come off the queue) to the rear (where things are added to the queue).
