C语言实现三子棋源代码

本文实例为大家分享了C语言实现三子棋的具体代码，供大家参考，具体内容如下

效果如下：

代码实现：

头文件部分

#pragma once
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#define ROW 3
#define COL 3

//函数声明
void Initboard(char board[ROW][COL], int row, int col);
void Displayboard(char board[ROW][COL], int row, int col);
Player(char board[ROW][COL], int row, int col);
Computer(char board[ROW][COL], int row, int col);
char Judge(char board[ROW][COL], int row, int col);
