环境VS

分三个模块，一个测试模块，一个头文件，一个游戏实现模块第一步：设立一个菜单

头文件

#include<stdio.h>
#include<stdlib.h>
#include<time.h>
#define ROW 3
#define COL 3
void Initboard(char board[ROW][COL], int row, int col);//初始化棋盘
void Displayboard(char board[ROW][COL],int row,int col);//打印棋盘
void Player_move(char board[ROW][COL], int row, int col);//玩家下棋
void Computer_move(char board[ROW][COL], int row, int col);//电脑下棋
char is_win(char board[ROW][COL], int row, int col);//判断输赢

 测试模块

#include"game.h"
void menu()
{
	printf("******************\n");
	printf("*****1.play*******\n");
	printf("*****0.exit*******\n");
	printf("******************\n");
}
void game()
{
	char ret = 0;
	char board[ROW][COL] = { 0 };
	Initboard(board, ROW, COL);//初始化棋盘
	Displayboard(board, ROW, COL);//打印棋盘
	while (1)
	{
		Player_move(board, ROW, COL);//玩家下棋
		Displayboard(board, ROW, COL);
		printf("\n");
		ret = is_win(board, ROW, COL);
		if (ret != 'c')
		{
			break;
		}
		Computer_move(board, ROW, COL);//电脑下棋
		Displayboard(board, ROW, COL);
		if (ret != 'c')
		{
			break;
		}
	}
	if (ret == '*')
		printf("玩家胜");
	else if (ret == '#')
		printf("电脑胜");
	else
		printf("平局");
}
void test()
{
	menu();
	int input=0;
	do
	{
		printf("请选择");
		scanf("%d", &input);
		switch(input)
		{
		case 1:
			game();
			break;
		case 0:
			printf("退出");
			break;
		default:
			printf("请重新选择");
			break;
		}
	} while (input);
}
int main()
{
	srand((unsigned int)time(NULL));//时间戳
	test();
	return 0;
}
