用C++写一个五子棋游戏代码

下面是一个简单的五子棋游戏的代码，其中包括显示游戏界面、玩家与电脑下棋、判断胜负等功能。

#include <stdio.h>
#include <stdlib.h>
#include <time.h>

#define CHESSBOARD_SIZE 15
#define PLAYER_CHESS 'X'
#define COMPUTER_CHESS 'O'

// 五子棋棋盘
char chessboard[CHESSBOARD_SIZE][CHESSBOARD_SIZE] = {0};

// 打印游戏界面
void print_game_board()
{
    printf(" ");
    for(int i = 0; i < CHESSBOARD_SIZE; i++)
    {
        printf(" %d", i + 1);
    }
    printf("\n");
    for(int i = 0; i < CHESSBOARD_SIZE; i++)
    {
        printf("%d", i + 1);
        for(int j = 0; j < CHESSBOARD_SIZE; j++)
        {
            printf(" %c", chessboard[i][j]);
        }
        printf("\n");
    }
}

// 判断胜负
int check_win(int x, int y, char chess)

    // 判断横向
    int count = 0;
    for(int i = x - 4; i <= x; i++)

请注意，此代码只是一个简单的实现，如果您想要实现更完整的五子棋游戏，可能需要添加更多的功能和规则。
