[C++知识库]完成三子棋游戏代码

新建一个game.h文件，写入预处理信息，现有的函数的头文件和自定义函数的声明。

#define _CRT_SECURE_NO_WARNINGS 1
#define ROW 3
#define COL 3

#include<stdio.h>
#include<time.h>
#include<stdlib.h>
#include<Windows.h>

//初始化棋盘
void InitBoard(char board[ROW][COL], int row, int col);
//打印棋盘
void DisplayBoard(char board[ROW][COL], int row, int col);
//玩家下棋
void PlayerMove(char board[ROW][COL], int row, int col);
//电脑下棋
void ComputerMove(char board[ROW][COL], int row, int col);
//判断游戏进展情况
char CheckWin(char board[ROW][COL], int row, int col);

新建一个game.c的源文件

#include"game.h"

?新建一个test.c的源文件

#include"game.h"

void menu()

	printf("请输入:>\n");
}

void game()
{
	char ret = 0;
	char board[ROW][COL];
	//初始化棋盘，初始化为空格
	InitBoard(board, ROW, COL);
	//打印棋盘
	DisplayBoard(board, ROW, COL);
	while (1)

	Sleep(1000);
}

int main()
