通过C++来实现2048小程序
我通过思维导图来画出了整个框架，大家可以参考一下
#include <iostream>
#include <stdio.h>
#include <windows.h>
#include <vector>
#include <time.h>
#include <stdlib.h>

const int COL = 4;
//定义一个全局数组
static int data[ROW ][COL];
//上下左右
int const UP = 1;
int const DOWN = 2;
int const LEFT = 3;
int const RIGHT = 4;
static bool move_flag = false;//默认为无效移动
inline int getrand(){ //通过时间作为随机种子，获取随机数
srand(static_cast<unsigned int>(time(nullptr)));
return rand();
}
