代码内有详细注释

源.c代码如下:

#define _CRT_SECURE_NO_WARNINGS

#include"Game.h"

void Game()
{
 char result = 0;
 //创建棋盘
 char board[ROW][COL] = { 0 };
 //初始化棋盘
 Init_board(board, ROW, COL);
 //打印棋盘
 Print_board(board, ROW, COL);
 while (1)
 {
 //玩家走棋
 printf("玩家走棋:\n");
 Player_move(board, ROW, COL);
 Print_board(board, ROW, COL);
 //判断游戏状态 继续 平局 玩家胜 电脑胜
 result = Game_state(board, ROW, COL);
 if (result != 'C')
 {
  break;
 }
 //电脑走棋
 printf("电脑走棋:\n");
 Computer_move(board, ROW, COL);
 Print_board(board, ROW, COL);
 //判断游戏状态 继续 平局 玩家胜 电脑胜
 result = Game_state(board, ROW, COL);
 if (result != 'C')
 {
  break;
 }
 }
 if (result == 'X')
 printf("玩家胜\n");
 else if (result == 'O')
 printf("电脑胜\n");
 else
 printf("平局\n");
 printf("再来一局请输入1,退出请输入0\n");
}

void Menu()
{
 int input = 0;
 printf("*****************************\n");
 printf("**** 1.play  2.exit  ****\n");
 printf("*****************************\n");
 do
 {
 printf("请选择:\n");
 scanf("%d", &input);
 switch (input)
 {
 case 1:
  Game();
  break;
 case 0:
  printf("退出游戏\n");
  break;
 default:
  printf("请输入1或0\n");
  break;
 }
 } while (input);
}

int main()
{
 //设置随机数起点
 srand(time(NULL));
 //写一个游戏
 //打印菜单
 Menu();
 return 0;
}

#include<stdio.h>//NULL
#include<time.h>//time
#include<stdlib.h>//rand srand

#define ROW 3
