三子棋游戏（c语言实现）

</pre>一说到写个三子棋游戏，首先我们得想到有个棋盘初始化和棋盘打印函数。<p></p><p>接下来，玩游戏阶段，人玩游戏，电脑玩游戏，各写一个函数，每次下完棋都得判断有没有人赢了游戏，若有人赢了，游戏退出，否则继续游戏。在这过程中，还有可能棋盘满</p><p>了，所以写个判断棋盘是否满的的函数，棋盘满了，程序结束，没人赢，此时就平局。</p><p>当然了，还有一些辅助函数，比如game函数，print_manu函数，只是起到封装的作用，也防止main函数过长。</p><p>程序亮点：巧妙地运用了逗号表达式（在电脑下棋游戏中），但是，得用个计数器，while语句执行一次就好，不然电脑就耍赖了。</p><p>                   程序有一定的容错性。</p><p>程序缺陷：游戏只能一次性玩一局。</p><p>                   只写了人机游戏，没有人人游戏。这个需要之后继续实现。</p><p> <span style="background-color:rgb(255,102,102)"> game.c文件</span></p><pre name="code" class="objc">#define _CRT_SECURE_NO_WARNINGS 1
