Visual Studio 2015"非标准语法；使用“&"创建一个指向成员的指针"

2021-12-30 00:00:00 c++ visual-studio-2015

我正在学习 C++ 并尝试制作一个井字游戏小游戏.但我不断得到 C3867，非标准语法；使用&"创建一个要记住的指针.

I am learning C++ and try to make a small game of Tic Tac Toe. But I keep on getting C3867, non-standard syntax; use '&' to create a pointer to remember.

这是我的 TicTacToe.h :

This is my 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;
};

这是我的 TicTacToe.cpp :

And here is my 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|
";
  for (int i = 0; i < 3; i++) {
    cout << "--------
";
    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: 
";
  cin >> player1Name;
  _player1Name = player1Name;
}

void TicTacToe::setName2(string player2Name) {
  cout << "Enter your name, player 2: 
";
  cin >> player2Name;
  _player2Name = player2Name;
}

string TicTacToe::getName1() { return _player1Name; }

string TicTacToe::getName2() { return _player2Name; }

void TicTacToe::setSign1(string player1Sign) {
  cout << "What will you sign be?(X/O)
";
  cin >> player1Sign;
  if (player1Sign != "X" && player1Sign != "O" && player1Sign != "x" &&
      player1Sign != "o") {
    cout << "Invalid input, try again.
";
    cin >> player1Sign;
  }
  _player1Sign = player1Sign;
}

void TicTacToe::setSign2(string player2Sign, string player1Sign) {
  cout << "What will you sign be?(X/O)
";
  cin >> player2Sign;

  if (player2Sign != "X" && player2Sign != "O" && player2Sign != "x" &&
          player2Sign != "o" ||
      player2Sign == player1Sign) {
    cout << "Invalid input, try again.
";
    cin >> player2Sign;
  }
  _player2Sign = player2Sign;
}

void TicTacToe::player1Move(string coordX) // ERROR
{
  cout << "Enter X: " << endl;
  cin >> coordX;
  _coordX = coordX;
}

void TicTacToe::player1Turn() {
  cout << "Player 1 turn !
";
  TicTacToe Board;
  Board.player1Move;
}

void TicTacToe::player2Turn() {
  cout << "Player 2 turn !
";
  TicTacToe Board;
  Board.player1Move;
}

我已经尝试了有关此错误的其他问题中的所有内容，但没有奏效.您如何解决此错误?

I have tried everything in other questions about this error but they didn't work. How do you fix this error?

推荐答案

问题在于包含以下内容的行(在您的代码中出现两次):

The problem is with the lines which contain the following (it appears twice in your code):

Board.player1Move;

Player one move 是一个接收 std::string 参数作为输入的函数.为了调用它，您需要创建一个 std::string 对象并将其作为函数的参数传递.如果您希望将字符串作为输入，可以使用以下语法:

Player one move is a function which receive an std::string parameter as an input. In order to call it you'll need to create an std::string object and pass it as an argument for the function. You can use the following syntax if you want the string to be given as an input:

std::string move;
cin >> move;
Board.player1Move(move);

另外，注意 player2Turn 应该调用 Board.player2Move 而不是 Board.player1Move.

Also, notice that player2Turn should call Board.player2Move instead of Board.player1Move.
