我遇到一个问题，我似乎无法正确切换播放器（从X到O），它只是在两者之间随机切换。到目前为止，这是我的代码：

#include <iostream>
#include <conio.h>
#include <windows.h>
using namespace std;

bool gameover = false;
char position[3][3] = {'1','2','3','4','5','6','7','8','9'};
char player = 'X';
char player2 = 'O';
void draw(){
    for (int i = 0; i < 3; i++) {
        for (int j = 0; j < 3; j++) {
            cout << position[i][j] << " ";
        }
        cout << endl;
    }
}


void input(){
    if (_kbhit()) {
        switch (_getch())
        {
        case '1':
            position[0][0] = player;
            break;
        case '2':
            position[0][1] = player;
            break;
        case '3':
            position[0][2] = player;
            break;
        case '4':
            position[0][3] = player;
            break;
        case '5':
            position[0][4] = player;
            break;
        case '6':
            position[0][5] = player;
            break;
        case '7':
            position[0][6] = player;
            break;
        case '8':
            position[0][7] = player;
            break;
        case '9':
            position[0][8] = player;
            break;
        }
    }

}

void logic() {
    if (player == 'X') {
        player = 'O';
    }
    else {
        player = 'X';
    }
}

int main (){
    while (!gameover) {
        input();
        draw();
        logic();
        system("cls");
    }
    return 0;
}

很抱歉，这个问题已经被问过很多次了，但是我似乎找不到解决方法。我曾尝试将系统（'cls'）改为暂停，但也不起作用。
