大家好!我是 C++ 的初学者,正在做这个问题。该问题提到了以下代码并要求某些解决方案。
问题要求:
- 测试类 (playerTest.cpp) 的驱动程序文件(主程序)
- 播放器类头文件和实现文件——单独的接口和实现(player.h & playerImp.cpp)
- 大厅类头文件和实现文件 -- 单独的接口和实现
由于这是一个实现和标头问题,我尝试研究该主题。我观看了 thenewboston (Bucky)、MissouriSandTCourses、MicrosonicDev 等的 YouTube 视频,但我无法理解任何概念。这本书(Beginning c++ through game programming)在这个话题上根本没有帮助。
我也尝试阅读一些文章,但没有任何帮助。

我不明白你的问题。你能具体说明一下吗?你想达到什么目的?你有什么问题?

相关/欺骗,我认为:stackoverflow.com/questions/9579930/…

问题是要求创建单独的头文件和实现文件: • 测试类的驱动程序文件(主程序)(playerTest.cpp) • 播放器类头文件和实现文件——单独的接口和实现( player.h & playerImp.cpp) • 大厅类头文件和实现文件——单独的接口和实现

你已经把它分开了。现在只需将
class块复制并粘贴到.h文件中,并将函数实现复制并粘贴到.cpp文件中。在.cpp文件和主文件中包含.h文件。就是这样。
