分段错误（核心转储）C++

Question

经过研究，我相信我了解"Segmentation fault" 错误是什么。但是，即使在逐行注释掉代码之后，我似乎也无法找到故障发生的位置来修复它。有没有我忽略的东西导致了这个错误？以下是我运行代码时显示的内容：

Answer 1

您有一个名为bigDeck 的std::vector，并且在DealQCard 中，您尝试访问它的第0 个元素，尽管事实上它没有任何元素。您的意思是在bigDeck 中放一些卡片吗？

Answer 2

尝试访问不存在的内存或正在被其他进程使用的内存也会导致分段错误（核心转储）。

Core dumped 意味着程序状态已被记录，即它在内存和处理器中的资源。
