Edmonds Community College Game Connect Four Program Project

The goal of this lab is to program the game Connect Four. See [1] if you are unfamiliar with the game.

You are already given a file main.cpp (which you may not change). 

You have to implement the remaining of the game. 

Next to the main.cpp, your program will contain the files game.h, game.cpp, players.h, and players.cpp. 

The file game.h defines an enumeration GameState which represents the possible game states, an enumeration BoardField which represents the possible state of a field of the game-board, and the class Game. 

The file players.h defines an abstract class Player, a class HumanPlayer, and a class AiPlayer.

 The classes HumanPlayer and AiPlayer are subclasses of the class Player.

 Make sure that the header files only contain declarations.

 You may only implement class members in the corresponding .cpp-files. 

Player Classes 

Player. The abstract class Player defines the interface which is used by the Game class.

 It must contain an abstract function getNextTurn which takes as parameter the current game (to read the game state and board) and returns an integer in the range from 1 to 7 representing the column in which the players put their next stone. 

HumanPlayer. Represents a human player. Its function getNextTurn reads an integer from the terminal and returns it. It may not create any output! 

AiPlayer. Representsanon-humanplayer.ItsfunctiongetNextTurnfirstdeterminesinwhichcolumn the player can add its next stone. 

Then, out of all possible columns, one is picked randomly and returned.

 It also outputs the selected column together with a newline-character to the terminal. 

For example, if column 3 is selected, the output is “3n”. 

Game Class 

The class Game contains the logic for the game. 

It determines if turns of players are valid, keeps track of the board, determines if a player has won, and updates its state accordingly. 

The class has the members listed below.

 Feel free to add additional private members if they improve the overall code quality. 

BoardWidth. A public constant with the value 7.
BoardHeight. A public constant with the value 6.
Game(Player &p1, Player &p2). Public constructor which takes the players of the game as 

arguments.
getState() cost. A public function which returns the current state of the game.
isRunning() const. A public function which returns true if the game is still running, or false if 

the game concluded with either a draw or a player winning.
operator() (int x, int y) const. Publicly overrides the ()-operator. Returns the state at the 

board at the given coordinate. The top left element has coordinate (0, 0). Returns Empty if the coordinate is out of range of the board. 

nextTurn(). Public function which performs the next turn. To do so, the Game class calls the function getNextTurn of the current player. If the return value is invalid, nothing happens. 

In case of a valid return value, the function processes the move of the player. 

That is, it updates the board, determines if the current player won or if a draw was reached, and updates the game state accordingly.
