Question

这是我的main.cpp

#include "DiceTwentyOne.h"
#include <string>
#include <iostream>
#include <conio.h>
using namespace std;
DiceTwentyOne game;
string play;
void playGame(string play)
{

    int turns = 0;

    while(play == "yes" && turns !=3)
    {
        cout << "Your score is: " << game.playGame(true);
        cout << endl;
        cout << "Would you like to roll?[yes,no]";
        cin >> play;
        cout << endl;
        turns++;
    }

    cout << "Dealers score: " << game.playGame(false) << endl;

    if(game.winLoss())
    {
        cout << "You win";
    }
    else
    {
        cout << "Dealer wins";
    }
}
int main ()
{
    cout << "Would you like to roll?[yes,no]";
    cin >> play;
    cout << endl;
    if(play == "yes")
    {
        playGame(play);
    }
    else
    {
        cout << "Have a nice day.";
    }
    getch();
    return 0;
}

            dealer.setTurns(tempTurn);

            tempTurn = -1 * player.getTurns();

            player.setTurns(tempTurn);

            return dealer.getScore();
        }
    }

    return -1;
}

bool DiceTwentyOne::winLoss()
{

    if(dealer.getScore > 21)
    {
        return false;
    }

    else if(player.getScore() > dealer.getScore())
    {
        return true;
    }

    else
    {
        return false;
    }
}

我收到此错误，并且我尝试为getTurns分配值。有谁知道如何解决这个问题？

Answer 1

您使用playGame()致电bool，但定义为playGame(std::string)。
