The following shows code to play a guessing game in which two players attempt to guess a number. Your task is to extend the program with objects that represent either a human player or a computer player.
bool checkForWin(int guess, int answer)
{
if (answer == guess)
{
cout << "You're right! You win!" << endl;
return true;
}
else if (answer < guess)
cout << "Your guess is too high." << endl;
else
cout << "Your guess is too low." << endl;
return false;
}
void play(Player &player1, Player &player2)
{
int answer = 0, guess = 0;
answer = rand( ) % 100;
bool win = false;
while (!win)
{
cout << "Player 1's turn to guess." << endl;
guess = player1.getGuess( );
win = checkForWin(guess, answer);
if (win) return;
cout << "Player 2's turn to guess." << endl;
guess = player2.getGuess( );
win = checkForWin(guess, answer);
}
}
The play function takes as input two Player objects. Define the Player class with a virtual function named getGuess(). The implementation of Player::getGuess() can simply return 0. Next, define a class named HumanPlayer derived from Player. The implementation of HumanPlayer::getGuess() should prompt the user to enter a number and return the value entered from the keyboard. Next, define a class named ComputerPlayer derived from Player. The implementation of ComputerPlayer::getGuess( ) should randomly select a number from 0 to 100. Finally, construct a main function that invokes play(Player &player1, Player &player2) with two instances of a HumanPlayer (human versus human), an instance of a HumanPlayer and ComputerPlayer (human versus computer), and two instances of ComputerPlayer (computer versus computer).
