How do I code and pass a (reference to a std::vector)?

Question

I can\'t seem to get this right.

class Tree
{
    Node*   root;
    vector& dict;
} 

class Node
{
    vector& dict;
    char*   cargo;
    Node    left;         


        

Answer 1

You can initialize a reference only in an initialization list of a constructor. For instance,

Tree::Tree( vector& d ) : dict(d) 
{
  ...
}
