如果C++是新的，我建议先尝试一些基本程序。你还有其他问题，比如你的常数成员没有被初始化。缩进你的代码可能是个好主意。我只是在这里为你做的，但是这不会修复你的计算机上的文件：你必须包括一个“提供者”。“头文件。我的.cpp文件中包含了一个提供程序.h，但我记得有人告诉我不要在头文件中包含其他.h文件。Chris，你能告诉我如何使用语法吗？我想了解初始化的实际含义（我想我只需要声明一个成员来初始化它就可以了？）我甚至不能在我的h文件中包含一个provider.h，因为出于某种原因，它告诉我“没有这样的文件或目录”，我试过了，它仍然不起作用。我得到了一个错误"调用“Provider:：getResponseToGuess”时没有匹配的函数。我正在尝试一系列不同版本的函数，但无法得到一个有效的函数。好吧！我的问题是我没有在getResponseToGuess中传递正确数量的参数！编译器没有提到它，所以我甚至没有想过进行双重检查！添加一个对象非常有效，谢谢！！！我还有另一个同样的问题，但出于某种原因，同样的方法似乎不起作用；
