  • 给一手扑克牌分类

    最近看了《C语言程序设计程序 现代方法》,里面一个问题挺有意思的。原本自己写了一个,但结构混乱,示例程序条理清晰,全局变量用的挺好,故又按照书上的程序敲了一遍。

    每次读取一手五张牌,然后根据下列类别把手中的牌分类(列出的顺序依次是从最好类别到最坏类别):   
    Straight flush: 同花顺的牌(即顺序相连又都是同花色)   
    Four-of-a-kind: 四张相同的牌(四张牌级别相同)   
    Full house: 三张花色相同和两张花色相同的牌(三张牌是同样的花色,而另外两张牌是同样的花色)   
    Flush: 同花色的牌(五张牌是同花色的)   
    Straight: 同顺序的牌(五张牌的级别顺序相连)   
    Three-of-a-kind: 三张相同的牌(三张牌级别相同)   
    Two pairs: 两对子   
    Pair: 一对(两张牌级别相同)   
    High card: 其它牌(任何其它情况的牌) 

    代码如下:  

      1 #include <stdbool.h>
      2 #include <stdio.h>
      3 #include <stdlib.h>
