编程：模拟实现争上游扑克牌游戏。争上游扑克牌游戏允许两名以及两名以上的玩家参加，也允许玩家自由从扑克游戏中退出。争上游扑克牌游戏规则规定，哪位玩家先打出所有的牌先赢。最后出完牌则输了。假设，每个玩家在每轮游戏中只能出一张牌，测试游戏的程序代码如下所示程序清单3-1所示，请采用合理的面向对象程序设计模式实现这个扑克游戏。-Programming: Analog strive for poker games. Strive for poker games allow two and two more players to participate, and also allows players to freely exit from the poker game. Strive for poker games rules, which player to play all the cards first win. Finally the finished brand is lost. Assuming that each player in each round only out of a brand, test the game code as shown below in Listing 3-1, please use the object-oriented programming model to achieve this poker game.
