C++ 面向对象问题-派生类

我试图找出对Class:：Function（）的未定义引用。这个项目是一个我看到了一些回应的项目，我也看到了其他项目的回应，看起来代码是相似的，但我似乎找不到我的具体问题的答案。我正在尝试使用2.h文件、它们的实现文件和驱动程序来简单地从一副牌中发牌。我遇到了一个难题，因为我不能100%确定如何使用派生类。我当前在编译时的错误如下：

• 对“Deck:：shuffleCards（）”的未定义引用。
• 对“Deck:：dealCard（）”的未定义引用。
• 对“Card:：getCard（）const”的未定义引用

非常感谢您提供的任何帮助。这是密码

对于（int i=0；i无法确保您正在将.cpp文件添加到makefile/project。这是一个编译错误，不是语法错误，与派生类无关。这可能是因为没有创建.o文件，因此编译器无法链接它们。发布makefile会很有用。我实际上是在使用代码块进行编译。还有其他建议吗那太棒了。
