初始c语言（三子棋）

图片笔记如上

———————————————————————————————————————————

文字笔记：

三子棋：
1.结尾加n
2.多加注释
3.单字符用单引号
4.比几小就模几

1.头文件 

#pragma once
//头文件包含
#include

//符号的定义
#define ROW 3
#define COL 3

//声明函数


//初始化棋盘
void InitBoard(char Board[ROW][COL],int row,int col);

//打印棋盘
void PrintBoard(char Board[ROW][COL], int row, int col);

//玩家行动
void Playermove(char Board[ROW][COL], int row, int col);
