在VS编译器的小黑框框里实现5x5棋盘的的三子棋

程序包括test.c（游戏测试）game.c（游戏源文件）和game.h（头文件）三个部分

game.h

#ifndef __GAME_H__

    #define COLS 5   //定义棋盘的列数
    
    #include <stdio.h>
    #include <stdlib.h>
    #include <time.h>
    #include <string.h>
    
     void init_board(char board[ROWS][COLS], int row, int col);   //初始化棋盘
     void display(char board[ROWS][COLS], int row, int col);      //打印5*5的棋盘
     void player_move(char board[ROWS][COLS], int row, int col);  //玩家下棋
     void computer_move(char board[ROWS][COLS], int row, int col);//电脑下棋
     char check_win(char board[ROWS][COLS], int row, int col);    //判断是否赢
    
    #endif //__GAME_H__
