這篇文章主要為大家詳細(xì)介紹了C語言實現(xiàn)三子棋（井字棋）算法，文中示例代碼介紹的非常詳細(xì)，具有一定的參考價值，感興趣的小伙伴們可以參考一下

本文實例為大家分享了C語言實現(xiàn)三子棋算法，供大家參考，具體內(nèi)容如下

游戲文件主干（test.c）:

#include"game.h"

 printf("**********          0.exit             *********\n");
 printf("************************************************\n");
}
void game()//游戲玩法實現(xiàn)主體（粗略）
{
 printf("三子棋:>\n");
 char board[LINE][ROW];
 Init_checkerboard(board, LINE, ROW);//初始化棋盤
 Print_checkerboard(board, LINE, ROW);//打印棋盤
 char ret = 0;
 while (1)//條件為1可以一直循環(huán)
 {
  Player_game(board, LINE, ROW);//玩家行動
  Print_checkerboard(board, LINE, ROW);//玩家行動后的棋盤
  ret = Iswin(board, LINE, ROW);//判斷是否出現(xiàn)勝負(fù)
  if (ret != 'c')//出現(xiàn)勝負(fù)就跳出循環(huán)

   break;
  }
  Commputer_game(board, LINE, ROW);//電腦回合
  Print_checkerboard(board, LINE, ROW);//電腦行動后的棋盤
  ret = Iswin(board, LINE, ROW);//判斷是否出現(xiàn)勝負(fù)
  if (ret != 'c')
