无法使功能正常工作

Question

我正试图让这个tic tac脚趾程序能够正常工作，但我处于完全丧失状态。我在网上搜索过，但只会让我更困惑。我无法使更改播放器功能正常工作（playerTurn），并且我无法获取检查配合是否正常工作的功能（checkTie）。请，任何帮助将如此赞赏。这里是我有：

#include <iostream> 
#include <stdlib.h> 
#include <cmath> 
#include <math.h> 
#include <cstdlib> 
#include <string> 

using namespace std;

bool checkTie(char[][4]); 
int playerTurn(int); 

const char PLAYER1='X'; 
const char PLAYER2='O'; 


int main() 
{ 
    //variable for player 
    int playerNum=1; 

    //Game over variable 
    bool bGameOver=false; 

    //Variable to hold winner status 
    char winner; 
    bool tie; 

    //Variable player 
    string player; 

    //Player mark 
    char mark; 

    //Constants for board size 
    const int ROWS=4; 
    const int COLS=4; 

    char board[ROWS][COLS] = {{' ', '1', '2', '3'}, 
          { '1', '*', '*', '*'}, 
          {'2', '*', '*', '*'}, 
          {'3', '*', '*', '*'}}; 


    //counter variable 
    int i; 
    //display the board    
    for (int i = 0; i <ROWS; i++) 
      { 
       cout << board[i][0] << "\t" << board[i][1] << "\t" << 
       board[i][2] << "\t" << board[i][3]<< endl; 
      }//end for     


    //Variables to hold selection 
    int rowx, colx; 

while(!bGameOver)//Main game loop

    if(playerNum=1) 
    { 
     player="Player 1"; 
     mark=PLAYER1;

    board[rowx][colx]=mark; 



    for (int i = 0; i <ROWS; i++) 
      {

      }//end for 

      //call checkwinner function

Answer 1

playerTurn（）正常工作;但是，在主游戏循环的顶部，您在if语句的测试中使用=而不是==，因此每次迭代时将playerNum重置为1。

至于checkTie，您需要提供详细信息，以何种方式无效。或者你可以通过记录所做出的动作次数来避免需要;如果在第九步之后没有人获胜，那么这场比赛是平局。
