Just to add to Ron's otherwise excellent explanation, a more real-world
example might be:

  class GameBoard {
  private:
    int rows;
    int cols;
  public:
    GameBoard( int n_rows, int n_cols )
      : rows( n_rows ), cols( n_cols ) {}
    GameBoard( const GameBoard& src )  // copy constructor
      : rows( src.rows ), cols( src.cols ) {}
  };

  class ChessBoard {
  public:
    ChessBoard() : GameBoard( 8, 8 ) {}
    ChessBoard( const ChessBoard& src ) // copy constructor
      : GameBoard( src ) {}
  };
