我正在學習C ++，并嘗試制作一個Tic Tac Toe的小游戲。但是我繼續得到非標準語法C3867。使用“＆”創建要記住的指針。這是我的TicTacToe.h：#pragma once#include <iostream>using namespace std;class TicTacToe{public:    TicTacToe();    string getName1();    string getName2();    void printBoard();    void clearBoard();    void setName1(string player1Name);    void setName2(string player2Name);    void setSign1(string player1Sign);    void setSign2(string player2Sign, string player1Sign);    void playGame(string player1Name, string player2Name,string    player1Sign,string player2Sign);                      void player1Move(string coordX);    void player1Turn();    void player2Turn();private:    char Board[3][3];    string _player1Name;    string _player2Name;    string _player1Sign;    string _player2Sign;    string _coordX;    string _coordY;};這是我的TicTacToe.cpp：#include "TicTacToe.h"#include <iostream>#include <string>TicTacToe::TicTacToe() {}void TicTacToe::playGame(string player1Name, string player2Name,                         string player1Sign, string player2Sign) {  TicTacToe Board;  Board.setName1(player1Name);  Board.setSign1(player1Sign);  Board.setName2(player2Name);  Board.setSign2(player1Sign, player2Sign);  Board.clearBoard();  Board.printBoard();}void TicTacToe::printBoard() {  cout << " |1|2|3|\n";  for (int i = 0; i < 3; i++) {    cout << "--------\n";    cout << i + 1 << "|" << Board[i][0] << "|" << Board[i][1] << "|"         << Board[i][2] << "|" << endl;  }}void TicTacToe::clearBoard() {  for (int i = 0; i < 3; i++) {    for (int j = 0; j < 3; j++) {      Board[i][j] = ' ';    }  }}void TicTacToe::setName1(string player1Name) {  cout << "Enter your name, player 1: \n";  cin >> player1Name;  _player1Name = player1Name;}void TicTacToe::setName2(string player2Name) {  cout << "Enter your name, player 2: \n";  cin >> player2Name;  _player2Name = player2Name;}string TicTacToe::getName1() { return _player1Name; }string TicTacToe::getName2() { return _player2Name; }我已經嘗試了其他所有有關此錯誤的問題，但它們沒有起作用。您如何解決此錯誤？
