三子棋游戏俗称井字棋，棋盘共三行三列，棋子摆满任一行一列或者对角线就胜利了。 用到的知识：数组传参时发生降维，降维成该数组内元素类型的指针。因此传参时实参会通过形参的改变而改变。代码整体分6块， 1.void Init(char board[][row], int x,int y); 初始化棋盘，棋盘模拟成一个二维数组board[][] 2.void Show(char board[][row], int x, int y);显示棋盘当前状态 3.char Judge(char board[][row], int x, int y);判断游戏是否结束，之后清算输赢 4.void C_move(char board[][row], int x, int y);模拟电脑落子 5.int Firstone();模拟抛硬币，决定落子先后顺序 6.void Game();游戏的执行顺序 头文件 game.h
