一、介绍
三子棋，民间传统游戏，又叫九宫棋、圈圈叉叉、一条龙等。将正方形对角线连起来，相对两边依次摆上三个双方棋子，只要将自己的三个棋子走成一条线，对方就算输了。如果两个人都掌握了技巧，那么一般来说就是平棋。一般来说，下在中间最有利，下在角上次之，下在边上再次之。最大的好处就是随便找个地方就可以玩这个简单而有趣的游戏了。

二、游戏实现
设计菜单
首先我们需要一个主函数main来设计游戏首页面菜单并来选择进入游戏或者退出游戏。在运行程序时可能玩家会输入错误，所以用while(1)来死循环游戏菜单页面。
#include"Game.h" int main() { //设置界面 system("title 简易三子棋"); system("mode con cols=32 lines=32"); system("color F0"); int select = 1; while (select) { printf("********************************\n"); printf("* 简 易 三 子 棋 *\n"); printf("********************************\n"); printf("* [1]开始 [0]退出 *\n"); printf("********************************\n"); printf("请选择：>"); scanf("%d", &select); if (select == 0) break; if (select != 1) { printf("输入有误！\n"); continue; } //开始游戏 BeginGame(); } printf("游戏结束，欢迎下次来玩！\n"); return 0; }

由运行截图可见，输入错误数字则会死循环，输入0则退出程序。
设计游戏流程
进入游戏后编写一个BeginGame函数来设计游戏流程，其中可以随机让电脑先下棋或者让玩家先下棋，和棋后判断你是否要重来。
int BeginGame() { //1 初始化游戏 InitializeGame(); char winner; //2 随机下棋者 int Return = RandomChessPlayer(); if (Return == 0) { //3 进入游戏 while (1) { //4 显示棋盘 ShowChessBoard(); //5 玩家下棋 PlayerMove(); //6 判断结果 winner = CheckResult(); if (winner != 'c') break; //7 电脑下棋 ComputerMove(); //8 判断结果 winner = CheckResult(); if (winner != 'c') break; } } else { while (1) { //4 电脑下棋 ComputerMove(); //5 判断结果 winner = CheckResult(); if (winner != 'c') break; //6 显示棋盘 ShowChessBoard(); //7 玩家下棋 PlayerMove(); //8 判断结果 winner = CheckResult(); if (winner != 'c') break; } } //9 宣布结果 if (winner == 'x') printf("恭喜你，玩家胜利.\n"); else if (winner == 'o') printf("很遗憾，电脑胜利.\n"); else { printf("和棋，是否继续[y/n]:"); while (1) { char a[1]; scanf("%s", a); if (a[0] == 'y') BeginGame(); else if (a[0] == 'n') break; else printf("输入有误，清重新输入：>"); } } return 0; }
以下是对游戏流程的细化实现
初始化游戏
我们可以用二维数组来确定一个3×3的版块，把3×3数组都初始化为空字符。
void InitializeGame() { for (int i = 0; i<ROW; ++i) { for (int j = 0; j<COL; ++j) { board[i][j] = ' '; } } }
显示棋盘
将3×3数组打印出来，一个简易的棋盘就做好了

void ShowChessBoard() { for (int i = 0; i<ROW; ++i) { printf(" %c | %c | %c \n", board[i][0],board[i][1],board[i][2]); if (i != ROW - 1) printf(" --- --- --- \n"); } }
下棋
设立玩家下棋为字符‘x’，电脑下棋为字符‘o’；玩家来通过坐标实现下棋，电脑先确定是否玩家下一步可能获胜，如果可能获胜，则下到玩家可能获胜的位置，否则随机下棋。
void PlayerMove() { printf("请玩家落子:\n"); int row, col; while (1) { printf("请输入棋子的坐标(row:col):>"); scanf("%d %d", &row, &col); if (board[row - 1][col - 1] != ' ') { printf("输入的位置已被占用，请重新输入....\n"); continue; } board[row - 1][col - 1] = 'x'; break; } } void ComputerMove() { int row, col; srand(time(0)); while (1) { //下玩家可能赢的位置 if (board[0][0] == 'x' && board[0][1] == 'x' && board[0][2] == ' ') { board[0][2] = 'o'; break; } else if (board[0][2] == 'x' && board[0][1] == 'x' && board[0][0] == ' ') { board[0][0] = 'o'; break; } else if (board[0][2] == 'x' && board[0][0] == 'x' && board[0][1] == ' ') { board[0][1] = 'o'; break; } else if (board[1][0] == 'x' && board[1][1] == 'x' && board[1][2] == ' ') { board[1][2] = 'o'; break; } else if (board[1][2] == 'x' && board[1][1] == 'x' && board[1][0] == ' ') { board[1][0] = 'o'; break; } else if (board[1][2] == 'x' && board[1][0] == 'x' && board[1][1] == ' ') { board[1][1] = 'o'; break; } else if (board[2][0] == 'x' && board[2][1] == 'x' && board[2][2] == ' ') { board[2][2] = 'o'; break; } else if (board[2][2] == 'x' && board[2][1] == 'x' && board[2][0] == ' ') { board[2][0] = 'o'; break; } else if (board[2][2] == 'x' && board[2][0] == 'x' && board[2][1] == ' ') { board[2][1] = 'o'; break; } else if (board[0][0] == 'x' && board[1][0] == 'x' && board[2][0] == ' ') { board[2][0] = 'o'; break; } else if (board[0][0] == 'x' && board[2][0] == 'x' && board[1][0] == ' ') { board[1][0] = 'o'; break; } else if (board[1][0] == 'x' && board[2][0] == 'x' && board[0][0] == ' ') { board[0][0] = 'o'; break; } else if (board[0][1] == 'x' && board[1][1] == 'x' && board[2][1] == ' ') { board[2][1] = 'o'; break; } else if (board[0][1] == 'x' && board[2][1] == 'x' && board[1][1] == ' ') { board[1][1] = 'o'; break; } else if (board[1][1] == 'x' && board[2][1] == 'x' && board[0][1] == ' ') { board[0][1] = 'o'; break; } else if (board[0][2] == 'x' && board[1][2] == 'x' && board[2][2] == ' ') { board[2][2] = 'o'; break; } else if (board[0][2] == 'x' && board[2][2] == 'x' && board[1][2] == ' ') { board[1][2] = 'o'; break; } else if (board[1][2] == 'x' && board[2][2] == 'x' && board[0][2] == ' ') { board[0][2] = 'o'; break; } else if (board[0][0] == 'x' && board[1][1] == 'x' && board[2][2] == ' ') { board[2][2] = 'o'; break; } else if (board[0][0] == 'x' && board[2][2] == 'x' && board[1][1] == ' ') { board[1][1] = 'o'; break; } else if (board[1][1] == 'x' && board[2][2] == 'x' && board[0][0] == ' ') { board[0][0] = 'o'; break; } else if (board[0][2] == 'x' && board[1][1] == 'x' && board[2][0] == ' ') { board[2][0] = 'o'; break; } else if (board[0][2] == 'x' && board[2][0] == 'x' && board[1][1] == ' ') { board[1][1] = 'o'; break; } else if (board[2][0] == 'x' && board[1][1] == 'x' && board[0][2] == ' ') { board[0][2] = 'o'; break; } else { //随机产生位置 row = rand() % ROW; col = rand() % COL; if (board[row][col] == ' ') { board[row][col] = 'o'; break; } } } }
判断结果
结果分为四种（玩家赢x，电脑赢o，和棋h，未下满继续c），当玩家或者电脑的棋子连成一行或者一列又或者连成对角线时，有一方获胜；当棋盘下满时，应判断为平局，所以判断输赢的函数就需要返回值。
