help with functions

I need help figuring out how to work this program.

c++ is telling me:`init_game' cannot be used as a function, along with 'ask_move' , and 'declare_winner'. Also a bit curious with void functions,

Rules of game:
• The game starts out with the user choosing the initial number of chips. It must be between 2 and
50 inclusively.
• Players alternate turns removing no more than half of the remaining
chips
• Whichever player takes the last chip wins the game.

your functions prototypes aren't formatted correctly.

  int init_game;
  int ask_move;
  bool is_move_legal;
  bool declare_winner;


should be:

  int init_game();
  int ask_move(bool, int);
  bool is_move_legal(int, int);
  bool declare_winner(bool);

To add onto what MintDropz said,
These are variables.

1

  int init_game;
  int ask_move;
  bool is_move_legal;
  bool declare_winner;


These are function prototypes (what you want here)

1

  int init_game();
  int ask_move(bool, int);
  bool is_move_legal(int, int);
  bool declare_winner(bool);

your if statements are buggy also.
you used it correctly in your main function

if (chips_in_pile == 0) 
	{ 
	  game_over = true; 
	  declare_winner(player1turn); 
	} 
	  else 
	  { 
		cout << "There are " << chips_in_pile << " chips left." << endl << endl;
		player1turn = !player1turn; 
	  }


but not in your function's definitions.

}
thanks for help
