C语言实现三子棋游戏附注释

本文实例为大家分享了C语言实现三子棋游戏的具体代码，供大家参考，具体内容如下

概述

三子棋棋盘为九宫格形式，玩家和电脑分别轮流落子，若有一方有三个棋连在一起的情况则胜。

实现过程

1、玩家交互菜单创建
2、棋盘创建与初始化
3、玩家与电脑落子
4、判定胜负关系

多文件实现

头文件 game.h

#ifndef __GAME_H__ #define __GAME_H__ #include #include #include #include #define ROW 3 #define COL 3 #define INIT ' ' //宏定义 空 #define WHITE 'X' //Player #define BLACK 'O' //Computer #define DRAW 'D' #define NEXT 'N' #pragma warning(disable:4996) extern void Game(); #endif

源文件 main.c

#include "game.h" void Menu() { printf("+-------------------------------+\n"); printf("| 1. Play 0. Exit |\n"); printf("+-------------------------------+\n"); } int main() { int select = 0; int quit = 0; while (!quit) { Menu(); printf("Please Select# "); scanf("%d", &select); switch (select){ case 1: Game(); break; case 0: quit = 1; break; default: printf("Enter Error, Try Again!\n"); break; } } printf("ByeBye!\n"); system("pause"); return 0; }
