c++ - 我的程序遇到了abort()错误，但由于它是程序的加载部分，所以我无法调试它？

每次我启动此应用程序时，它都会进入工作正常的菜单，但是在我按下start()之后，它只会中止运行，并且我有理论认为这是stoi，但我不确定。如您所见，我正在制作二十一点游戏，它使用数组然后将rand()随机从数组中移出，但随后必须将数组中的字符串转换为整数。但是然后您必须担心数组中的国王或0，所以我不得不考虑这一点。

最佳答案

问题出在您的stoi()上。这是因为yo'n'的值会一直延伸到代码的最后一个“else”部分，即使它们超出了1到9的范围。

您需要先对所有yo'n'变量进行范围检查，然后再将它们作为card_names [yo'n']传递给stoi。

正如smead所说，请编写更简洁的代码。太多的“如果”使它几乎不可读和不可调试。
