C++遊戲編程：卡牌遊戲

CardGame

一段時間一直喜歡玩歡樂鬥地主~~本來打算做出一個“跑得快”（有的地方叫爭上游），技術有點欠缺，於是做出了一個類似打牌的卡牌遊戲。
玩家將與兩個電腦玩家進行遊戲，一副牌總共有54張，洗牌後分爲3疊，玩家隨機得到一疊以開始。
每次只能出一張牌，牌的點數必須比上家的牌的點數大，無牌出則輸入 0 以PASS。率先清空牌庫的玩家獲勝。
所謂的54張牌其實就是類似撲克牌的54個數字，當然出牌的形式就是輸入自己“牌庫”裏的一個數字。

int c[] = {1,2,3,4,5,6,7,8,9,10,11,12,13,1,2,3,4,5,6,7,8,9,10,11,12,13,1,2,3,4,5,6,7,8,9,10,11,12,13,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15}; //一副牌
