Question

I am trying to have my constructor receive a reference to an object and store it in a private variable. I cant get a initiation list to work.
This is the headerfile:

private:
  Game &game;

public:     
  Player(Game & g): game(g);

Is using a initiation list the best way and what am i doing wrong?

Answer 1

Constructor initializer list is not just the “best” way to do it. It is the only way to do it.

Constructor initializer list is a part of constructor definition. This means that once you started to specify the initializer list, you have to supply the full definition for your constructor, including the body

public:     
  Player(Game &g): game(g)
    {}

If your constructor does not have anything else to do, the body will be empty (as in the example above). But you have to specify the body in any case.
