见鬼去吧,
更新:我已经添加了剩下的代码。我不想添加太多的代码,这样stackoverflow会阻止我发布。谢谢你的帮助!
在我的作业中,它声明“删除-从甲板工处删除具有给定值的卡的一个示例,并返回已删除的示例。”
一张卡相当于一套衣服的价值。
我初始化了一套完整的甲板手类,包括:红桃王牌,…,黑桃王牌,…,钻石王牌,…,梅花王牌。
我被告知该参数是一个值(表示为整数),在delete方法中,一旦找到该值的第一个示例,就创建一张卡片并从deckhand中删除。
举个例子,我试图删除五颗红心,但我的程序一直在删除五颗红心。我已经提供了我的代码和一些图片。
我会很感激你的帮助。谢谢您!

在@pault的帮助下,当我进行修改时,我的代码似乎正在运行。和@atp。我把我的代码复制到另一个文件,它就开始工作了。我真的不知道是什么问题。
谢谢大家的帮助!
