我的程序出现 abort() 错误,但由于它是程序的加载部分,我无法调试它?

My program gets an abort() error yet i cant debug it due to it being a loading part of the program?

每次我启动此应用程序时,它都会转到完美运行的菜单,但在我点击 start() 后它就会中止,我有一个理论认为它是 stoi,但我不确定。如您所见,我正在玩二十一点游戏,它使用数组然后使用 rand() 从数组中随机化,但随后它必须将字符串从数组转换为整数。但是你必须担心国王或数组中的 0,所以我必须考虑到这一点。

stoi() 将字符串转换为数字,但前提是您的字符串可以有效地转换为数字 (see documentation)。您的数组 card_names 包含多个非整数字符串("Ace"、"Jack" 等)。

我什至不确定你想在那里做什么:你的值 yo1yo5 已经包含卡号,那么你为什么需要将它转换为字符串然后回来?

另外,请使用数组!看到 yo1yo9card1card5 之类的东西让我的眼睛受伤:)

问题出在你的 stoi() 上。这是因为 yo'n' 的值会一直延续到代码的最后 "else" 部分,即使它们超出了 1 到 9 的范围。

您需要对所有 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 'if' 使它几乎不可读和无法调试。
