Answer Happy

C++
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.
