我有一个井字游戏的C程序，我的问题是所有的获胜条件都是好的，除了当第2列或第3列有3个“X”或“O”时，程序不会返回赢家，程序会一直运行，直到没有空格或另一个玩家（或电脑）获胜。但是，如果第一列有3个'X'或'O'，游戏将停止并返回赢家。我曾尝试修复它，但我无法找出我的代码有什么问题。
我的条件是

#include <stdio.h>
#include <time.h>
char board[3][3];
const char PLAYER ='X';
const char PLAYER2 = 'O';
const char BOT ='O';

void resetBoard(){
    int i,j;
    for(i=0;i<3;i++){
        for(j=0;j<3;j++){
            board[i][j]=' ';
        }
    }
}

void printWinner(char winner){
    if (winner==PLAYER){
        printf("\nPlayer 1 wins!");
    }
    else if(winner==BOT){
        printf("\nYou lose!");
    }
    else printf("\nTie!");
}

void printWinnerHuman(char winner){
    if (winner==PLAYER){
        printf("\nPlayer 1 wins!");
    }
    else if(winner==PLAYER2){
        printf("\nPlayer 2 wins!");
    }
    else printf("\nTie!");
}

void playerMove(){
    int x,y;
    do{
        printf("\nYou are X!");
        printf("\nEnter move (Ex: 0 2): ");
        scanf("%d %d",&x,&y);
        if (board[x][y]!=' '){
            printf("Space already taken\n");
            printBoard();
        }
        else {
            board[x][y]=PLAYER;
            break;
        }
    }
    while(board[x][y]!=' ');

}

void player2Move(){
    int x,y;
    do{
        printf("You are O!");
        printf("Enter your move (Ex: 1 2): ");
        scanf("%d %d",&x,&y);
        if(board[x][y]!=' '){
            printf("\nSpace already taken!");
            printBoard();

            y=rand()%3;
        }
        while(board[x][y]!=' ');
        board[x][y]=BOT;
    }
    else printWinner(' ');
}

char checkWinner(){
    int i;
    //check rows winner
    for(i=0;i<3;i++){
        if (board[i][0]==board[i][1]&&board[i][0]==board[i][2]){
            return board[i][0];
