The computer player in Programming Project 15.5 does not play the number guessing game very well, since it makes only random guesses. Modify the program so that the computer plays a more informed game. The specific strategy is up to you, but you must add function(s) to the Player and ComputerPlayer classes so that the play(Player &player1, Player &player2) function can send the results of a guess back to the computer player. In other words, the computer must be told if its last guess was too high or too low, and it also must be told if its opponent's last guess was too high or too low. The computer can then use this information to revise its next guess.
