我应该如何构建彼此依赖的C成员？

class Topic {
  Topic( Type T,String name );
};

class Reader {
  Reader (Topic,String name);
};

class Writer {
  Writer (Topic,String name);
};

我想做一个像这样的说话者课：

Talker (Type T,String name);

并使用构造函数生成成员Writer和Reader.

我在用指针做之间徘徊：

class Talker {
  Topic* m_Topic;
  Reader* m_Reader;
  Writer* m_Writer;

  Talker (Type T,String name) {
    m_Topic = new Topic (T,generateTopicName(name));
    m_Reader = new Reader (m_Topic,generateReaderName(name));
    m_Writer = new Writer (m_Topic,generateWriterName(name));
  }
};

直接对比：

class Talker {
  Topic m_Topic;
  Reader m_Reader;
  Writer m_Writer;


  Talker (Type T,String name) :
    m_Topic(T,name),m_Reader(m_Topic,generateReaderName(name)),m_Writer(m_Topic,generateWriterName(name))
  {}
};

我正在与同事交谈,显然后者因为依赖于成员初始化顺序而很糟糕.但是,它还有一个工作自动复制构造函数.

什么是更好的方式来做这样的事情,特别是如果成员对象列表变得更长？
