Answer 1

typedef multimap<string,Employee*> m_employees;

使m_employees成为专用地图类型的别名。您需要定义一个成员。改为使用：

typedef multimap<string,Employee*> EmpMap;
EmpMap m_employees;

Answer 2

m_employees不是变量，它是一个类型名称（来自Section类头中的typedef。在同一行，您使用newEmployee，就好像它是一个指向Employee实例的指针，但它实际上是一个副本实例。

错误：C2143：语法错误：缺少';'在'。'之前
