我正在尝试创建一个简单的井字游戏程序作为一些家庭作业的一部分，但难以检查游戏是否已获胜。一旦我启动程序并输入一个数字，它就会立即显示“玩家 2 获胜！” 我看不出我做错了什么。

#include "stdafx.h"
#include "tictactoe.h"

using namespace std;

void clearBoard(char gameBoard[])
{
    for (int i = 0; i < board_size; i++)
    {
        gameBoard[i] = free_char;
    }
}

void printBoard(char gameBoard[])
{
    system("cls");

    //for (int i = 0; i < board_width; i++)
    //{
        //cout << gameBoard[i] + 1 << " " << gameBoard[i] + 1 << " " << gameBoard[i] + 1 << endl;
    //}

    cout << gameBoard[0] << " " << gameBoard[1] << " " << gameBoard[2] << endl;
    cout << gameBoard[3] << " " << gameBoard[4] << " " << gameBoard[5] << endl;
    cout << gameBoard[6] << " " << gameBoard[7] << " " << gameBoard[8] << endl;
}

int askMove(int player)
{
    cout << "Player " << player << ", Select a square [1-9]: ";
    cin >> choice;

    return 0;
}

bool verifyMakeMove(char gameBoard[], int move, int player)
{
    if (player == 1)
    {
        mark = p1_char;
    }
    else
    {
        mark = p2_char;
    }

    if (move < 1 || move > 9)
    {
        cout << "You did not enter a number between 1 and 9. Try again." << endl;
    }

游戏开始时，棋盘是空白的。所有九个方格都具有相同的值，因此它们彼此相等。特别是，某行的三个方格都是相等的，所以根据你的逻辑，有人赢了。您需要添加额外的逻辑以避免该结论。

明显的问题是，checkEndGame当您查找三行时，您并没有检查空方格。测试应该更像

if (gameBoard[0] != 0 && gameBoard[0] == gameBoard[1] && gameBoard[1] == gameBoard[2])
    ^^^^^^^^^^^^^^^^^^^^

可能还有其他问题，您可以通过使用调试器单步执行代码来找到这些问题。
