c 语言实现三子棋游戏

1.头文件game.h:

#ifndef _GAME_H_
#define _GAME_H_


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


#pragma warning(disable:4996)


#define ROW 3
#define COL 3

void game();


#endif

2.main.c:

#include "game.h"

void menu()
{
	printf("#####################\n");
	printf("##1.play     2.exit##\n");
	printf("#####################\n");
	printf("Please Select:");

}


int main()
{
	int select;
	do{
		menu();
		scanf("%d", &select);
		switch (select){
		case 1:
			game();
			break;
		case 2:
			exit(0);
		default:
			break;

		}

	} while (1);
	system("pause");
