如何实现

组成：

二维数组：board[ROW][COL],定义一个ROW*COL的棋盘。

主要逻辑：

显示棋盘，提示用户下子，下子后判断，
1.显示棋盘很简单，慢慢凑棋盘就好
2. 用户下子，注意两个条件：棋子在棋盘里，下子位置未被占用。
3.判断是最难的，
方法：从下子位置的8个方向(上，下，左，右，右上，右下，左上，左下)计算相同棋子数目，然后将对角的棋子数相加,等于5说明有5子连线

主要函数中用到三个主要实现函数：

Showboard(board, ROW, COL)；//展示棋盘 Playermove(board, ROW, COL, cur);//玩家下注，cur表示哪个玩家下子 Judge(board, ROW, COL);//判断5子连线 Getcount(board[][COL], row, col, dir)//计算方向dir相同棋子数
