沒有贏家和十字架遊戲

Question

請看看下面的代碼

#include <iostream> 
#include <stdlib.h> 
#include <ctime> 

using namespace std; 

const char PLAYER_1 = 'O'; 
const char PLAYER_2 = 'X'; 


int row = 0; 
int col = 0; 

int winningStates[8][3][2] = {{{0,0},{0,1},{0,2}},{{1,0},{1,1},{1,2}},{{2,0},{2,1},{2,2}},{{3,0},{3,1},{3,2}}, 
           {{4,0},{4,1},{4,2}},{{5,0},{5,1},{5,2}},{{6,0},{6,1},{6,2}},{{7,0},{7,1},{7,2}}}; 

//This sets all the elements within the body to '-' to indicate that the square is free 
void intialise(char board[][3]) 
{ 
    for(int i=0;i<3;i++) 
    { 
     for(int a=0;a<=3;a++) 
     { 
      board[i][a] = '-'; 

     } 
    } 


} 

//This displays the board on the screen 
void display(char board[][3]) 
{ 
    for(int i=0;i<3;i++) 
    { 
     for(int a=0;a<3;a++) 
     { 
      cout << board[i][a] << "\t "; 

     } 
     cout << endl; 
    } 
} 

//setValue() sets the cell indicated by the parameter to the value that is contained within the symbol parameter 
void setValue(int row, int col, char symbol, char board[][3]) 
{ 
    board[row][col] = symbol; 
} 

//isFree() returns true if the cell identified by the parameter contains '-' 
bool isFree(int row, int col, char board[][3]) 
{ 
    if(board[row][col]=='-') 
    { 
     return (true); 
    } 
    else 
    { 
     return (false); 
    } 
} 

bool hasWon(char symbol,char board[][3]) 
{ 
    bool match = false; 

    row = 0; 
    col = 0; 

    for(int m=0;m<8;m++) 
    { 
     for(int s=0;s<3;s++) 
     { 
      row = winningStates[m][s][0]; 
      col = winningStates[m][s][1]; 

      if(board[row][col]==symbol) 
      { 
       match = true; 
      } 
      else 
      { 
       match = false; 
       break; 
      } 
     } 
    } 
    return match; 
    //return false; 
} 

int main() 
{ 
    char board[3][3]; 

    srand(time(0)); 

    bool gameOver = false; 

    char player = PLAYER_1; 

    int count = 0; 

    intialise(board); 
    // display(); 

    while(gameOver!=true) 
    {  

     do 
     { 
      row = rand()%3; 
      col = rand()%3; 
     } 
     while(! isFree(row,col,board)); 


     setValue(row,col,player,board); 
     if(player==PLAYER_1) 
     { 
      player = PLAYER_2; 
     } 
     else 
     { 
      player = PLAYER_1; 
     } 

     gameOver = hasWon(player,board); 

     if(gameOver==true) 
     { 
      cout << "WON" << endl; 
     } 
     count++; 

     if(count==9) 
     { 
      gameOver = true; 
      break; 
     } 


     display(board); 
     cout << endl; 


    } 
} 

在這段代碼中，我從來沒有得到「贏」的消息。而且，一個單元總是空閒的，沒有任何符號。 我運行這段代碼有多少次沒有關係，沒有人勝利！爲什麼是這樣？請幫忙！！

它看起來像一個邏輯錯誤，試試這個

bool hasWon(char symbol,char board[][3]) 
{ 
    for(int m=0;m<8;m++) 
    { 
     bool found_line = true; 
     for(int s=0;s<3;s++) 
     { 
      int row = winningStates[m][s][0]; 
      int col = winningStates[m][s][1]; 

      if(board[row][col]!=symbol) 
      { 
       found_line = false; 
       break; 
      } 
     } 
     if (found_line) 
      return true; 
    } 
    return false; 
} 

，我認爲它有助於選擇更好的變量名稱爲這樣的任務，match不是很好，因爲它沒有說你是什麼樣的匹配。這似乎是你的錯誤。
