c++實現簡陋版2048（控制檯）

無聊的時候想嘗試寫一下小遊戲，發現2048看起來是最容易的（無積分）
主要的點：

getch(）：頭文件：conio.h；一個不回顯函數，當用戶按下某個字符時，函數自動讀取，無需按回車
system(“cls”)： 頭文件：stdlib.h；是在C語言程序中，調用系統命令cls完成清屏操作。
以及win的句柄什麼的，沒怎麼學，過段時間仔細看看win32的API

具體邏輯：（代碼整潔之道還沒有看，變量命名和邏輯比較混亂）

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）的非零數字拉到一個數組裏
  {
   if(gameNum[j][i])
   {
    wasd[hold++]=gameNum[j][i];
    gameNum[j][i]=0;
   }
  }
  for(int xoy=1;xoy<hold;++xoy)//檢測是否存在相鄰的數字相等，相等則相加
  {
   if(wasd[xoy]==wasd[xoy-1])
   {
    wasd[xoy-1]+=wasd[xoy];
    wasd[xoy]=0;
   }
  }
  for(int xoy=0;xoy<hold;++xoy)//把處理過的數值填充進去
  {
   if(wasd[xoy])
   {
    gameNum[temp++][i]=wasd[xoy];
   }
  }
 }
}
