c++实现简陋版2048（控制台）

无聊的时候想尝试写一下小游戏，发现2048看起来是最容易的（无积分）
主要的点：

getch(）：头文件：conio.h；一个不回显函数，当用户按下某个字符时，函数自动读取，无需按回车
system(“cls”)： 头文件：stdlib.h；是在C语言程序中，调用系统命令cls完成清屏操作。
以及win的句柄什么的，没怎么学，过段时间仔细看看win32的API

具体逻辑：（代码整洁之道还没有看，变量命名和逻辑比较混乱）

void logicW()
{
 for(int i=0;i<xy;++i)
 {
  int wasd[xy]={0};
  int hold=0;
  int temp=0;
  for(int j=0;j<xy;++j)//把一行（列）的非零数字拉到一个数组里
  {
   if(gameNum[j][i])
   {
    wasd[hold++]=gameNum[j][i];
    gameNum[j][i]=0;
   }
  }
  for(int xoy=1;xoy<hold;++xoy)//检测是否存在相邻的数字相等，相等则相加
  {
   if(wasd[xoy]==wasd[xoy-1])
   {
    wasd[xoy-1]+=wasd[xoy];
    wasd[xoy]=0;
   }
  }
  for(int xoy=0;xoy<hold;++xoy)//把处理过的数值填充进去
  {
   if(wasd[xoy])
   {
    gameNum[temp++][i]=wasd[xoy];
   }
  }
 }
}
