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 main()//整个源文件的入口{ 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; default: printf("输入数字无效，请重新输入"); break; } } while (input); return 0;}
