三字棋游戏

 简单写了一个三字棋，实现了如下一些简单的功能。（1）棋盘的初始化（2）棋盘的打印（3）玩家下棋（4）电脑下棋（电脑可以对玩家下的棋堵）（5）判断输赢

分为test.c(测试文件)，game.c(游戏的实现函数)，game.h(游戏的头文件)

注意：

1.控制打印出类似的九宫格，来表示棋盘。
玩家落⼦子(输⼊入坐标的⽅方式)为 X
电脑落⼦子（随机坐标）为 0

2.玩家落子的细节：

（1）考虑玩家落子的合法性

（2）坐标是否占用

3.电脑落子

（1）当玩家下了两个子的时候，电脑要进行堵玩家，坐标要没有被占用

（2）若不进行堵玩家的时候随机进行下子，坐标要没有被占用

4.判断输赢

（1）玩家赢

（2）电脑赢

（3）平局

（4）继续游戏

先判断输赢，再判断平局，若无输赢无平局时游戏继续

test.c#define _CRT_SECURE_NO_WARNINGS 0#include"game.h"void menu(){printf("******************************\n");printf("****** 1.play     0.exit *****\n");printf("******************************\n");}//菜单void game(){char board[ROW][COL] = {0};int ret = 0;InitBoard(board, ROW, COL);//初始化棋盘DisplayBoard(board, ROW, COL);//打印棋盘while(1){PlayerMove(board, ROW, COL);//玩家走DisplayBoard(board, ROW, COL);ret = IsWin(board, ROW, COL);//判断输赢if (ret != ' ')break;ComputerMove(board, ROW, COL);//电脑走DisplayBoard(board, ROW, COL);ret = IsWin(board, ROW, COL);//判断输赢，返回‘X’是玩家赢，返回‘0’是电脑赢，返回‘q’是平局，返回‘ ’继续游戏if (ret != ' ')break;} switch (ret){case 'X':printf("恭喜！您赢了！\n");break;case '0':printf("很遗憾，您输了！\n");break;case 'q':printf("游戏平局！\n");break;default:break;}printf("显示全局情况\n");DisplayBoard(board, ROW, COL);}void test(){int input = 0;do{menu();printf("请选择模式：");scanf("%d", &input);switch (input){case 1:game();break;case 0:printf("退出游戏！\n");break;default:printf("选择错误，请重新选择：\n");break;}} while (input);}int main(){srand((unsigned int)time(NULL));test();system("pause");return 0;}
