本文实例为大家分享了C语言实现三子棋算法,供大家参考,具体内容如下

游戏文件主干(test.c):

#include"game.h"
 
void menu()//游戏菜单
{
 printf("************************************************\n");
 printf("**********          1.play             *********\n");
 printf("**********          0.exit             *********\n");
 printf("************************************************\n");
}
void game()//游戏玩法实现主体(粗略)
{
 printf("三子棋:>\n");
 char board[LINE][ROW];
 Init_checkerboard(board, LINE, ROW);//初始化棋盘
 Print_checkerboard(board, LINE, ROW);//打印棋盘
 char ret = 0;
 while (1)//条件为1可以一直循环
 {
  Player_game(board, LINE, ROW);//玩家行动
  Print_checkerboard(board, LINE, ROW);//玩家行动后的棋盘
  ret = Iswin(board, LINE, ROW);//判断是否出现胜负
  if (ret != 'c')//出现胜负就跳出循环
  {
   break;
  }
  Commputer_game(board, LINE, ROW);//电脑回合
  Print_checkerboard(board, LINE, ROW);//电脑行动后的棋盘
  ret = Iswin(board, LINE, ROW);//判断是否出现胜负
  if (ret != 'c')
  {
   break;
  }
  
 }
  if (ret == '*')
  {
   printf("玩家胜利!\n");
  }
  else if (ret == '#')
  {
   printf("电脑胜利!\n");
  }
  else
  {
   printf("平局\n");
  }
 
 
}

{
 int input = 0;
 srand((unsigned int)time(NULL));//电脑下棋的随机数
 do
 {
  menu();
  printf("请选择:>");
  scanf("%d", &input);
  switch (input)
  {
  case 1:
   game();//游戏函数主题(粗略)
   break;
  case 0:
   printf("您已退出游戏!\n");

   break;
  }

游戏的头文件(game.h):

#pragma once//保证被重复调用后依然只执行一次
#include<stdio.h>
#include<stdlib.h>
#include<time.h>
 
#define LINE 3
#define ROW  3
 
//初始化棋盘:
extern void Init_checkerboard(char board[LINE][ROW], int line, int row);
//打印棋盘:
extern void Print_checkerboard(char board[LINE][ROW], int line, int row);
//玩家走:
extern void Player_game(char board[LINE][ROW], int line, int row);
//电脑走:
extern void Commputer_game(char board[LINE][ROW], int line, int row);
//判断胜负:
extern char Iswin(char board[LINE][ROW], int line, int row);
