分段错误(C++)

Question

到目前为止,我的代码旨在创建一副牌,9 - ACE每个套件的价值,并向4名玩家交易5张牌.这些牌是交易3-2-3-2然后2-3-2-3每个玩家总共有5张牌.稍后我会编写代码来洗牌,然后在euchre游戏中对它们进行比较,但是现在我只想要处理这些卡片.无论如何,它并不完全正常,我愿意接受建议.我得到的错误是"分段错误:11"

让我"教你钓鱼":

调试器会告诉您故障的确切位置.如果你使用的是IDE(Xcode,Eclipse,VS),它有一个很好的接口,你应该使用它.如果不:

$ gdb my_executable
...
> run
...
Segmentation fault
> where

这将为您提供确切的位置(哪个行号的功能).
