1、井字旗C语言程序：运行环境：Turbo C/C+for Windows集成实验与学习环境或VC+6.0#define MAX 3#define Status int#define HUMAN_WIN 0 /人取得了胜利#define DRAW 1 /平局#define PLAYING 2 /没有决出胜负，正在进行游戏#define COMPUTER_WIN 3 /电脑取得了胜利#define HUMAN 0 /人#define COMPUTER 1 /机器#define EMPTY 2 /空#define FALSE 0 /假#define TRUE 1 /真#include #include。
2、 malloc.h/记录一步棋所需的所有信息：行数，列数，判断值typedef structint column;int row;int val;Nodes;int boardMAXMAX;/InitBoard初始化棋盘Status InitBoard()int row,column;for(row=0; row= MAX )return TRUE;/判断一列for( column = 0; column = MAX )return TRUE;/判断主对角线if( board 1 1 = side & board 2 2 = side& board 0 0 = side )return TRU。
3、E;/判断副对角线if( board 0 2 = side & board 1 1 = side& board 2 0 = side )return TRUE;return FALSE;/PositonValue返回落子后的状态 有四种状态在ConstNum.h中定义 COMPUTER_WIN, HUMAN_WIN, DRAW, PLAYINGStatus PostionValue()return IsWin(COMPUTER)?COMPUTER_WIN:(IsWin(HUMAN)?HUMAN_WIN:(BoardIsFull()?DRAW:PLAYING);/BestMovement判断最佳。
