C++ game - variant of Latrunculi

You are to implement the variant of Latrunculi described in the section above, for two human players. The game should not permit illegal moves. You must implement three ADTs, one for a player, one for the board, and one for the referee. At each turn, your program should prompt the appropriate player, to select a piece (grid position) and its destination. If an incorrect move is inputted (selected immobilized piece, selected opponent’s, piece) the program should recognize the error and continue to request correct input until the user provides it. When a player wins, the game should stop and a message indicating which player is victorious must be printed on the screen.
