c++ 學習curses庫，2048簡單小遊戲

2048 簡單小遊戲

遊戲規則：

用W,S,A,D控制上下左右操作 Q退出，R重新開始
當某個位置得到2048時獲勝
不能再有新的操作時失敗
移動：
每次移動時，有兩個相同的撞在一起會疊加，每個數字一次移動只能疊加一次，從邊上開始往後疊加
如向左移動：空 2 2 2 左移動 -> 空 空 2 4, 2 2 2 2 左移動 -> 空 空 4 4

每次操作後都會隨機選擇兩個空位進行添加2或4，新出4的概率10%
如果沒有空位就不添加，只有一個添加一個
重新開始隨機兩個位置添加，其餘清空

運行結果：

依賴庫

linux:

sudo apt-get install libncurses5-dev 

編譯：

Linux/Mac: g++ 2048.cpp -l ncurses -o 2048 
Windows: g++ 2048.cpp C:\pdcurs36\wincon\pdcurses.a -I C:\pdcurs36\ -o 2048 

爲了嘗試一下curses庫，做了這個小遊戲，代碼有點醜有待改進
