是模拟扑克牌发牌结果。 52张发给两个玩家

想问一下问题出在哪里，望指正，正在学习数组，另外也想问一下，中文英字符串的长度似乎有所区别？

设置card的值那里的设置值错了，取0-51之间的值就可以了，即rand()%52 ，以与数组的下标相符合；

然后发牌那里也是要从0开始到51结束，也是与数组下标相合；

另外中文字符长度大部分编码系统是2个字节，英文字符是1个字节，要看具体是哪种编码;

然后如果是模拟发牌，还需要考虑A到K的13种牌都需要有4张，每种牌的花色依次是四样，所以仅定义13张牌和4个花色，还需要加入一些控制条件来控制每种牌有四种，然后花色也依次是四样，所以可能实现有点复杂，这里仅简单用自定义出的52张牌的二维字符数组来实现这一点。

代码如下：
