C++2048游戏

本文主要是介绍C++2048游戏，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

最近听说2048游戏挺好玩就上网找个玩，结果没有一个完整的所以我只好自己写一个了。
源代码：

#include<stdio.h>
#include<stdlib.h>
#include<conio.h>
#include<windows.h>
#include<time.h>int null_count();//统计还有几个空格
void start_game();//开始游戏
void reset_game();//重置游戏，不清空记录
void move_left();//向左移动
void move_right();//向右移动
void move_up();//向上移动
void move_down();//向下移动
void refresh_show();//刷新显示屏
void add_rand_num();//添加随机数
