示例

class BaseA{};      //0 class Base0{};      //0 class Derived01:public Base0{};                  //1 class Derived012:public Derived01{};         //2 class Derived0123:public Derived012{};         //3 class Derived01234:public Derived0123{};     //4 class Derived012345:public Derived01234{};     //5 class Derived0123456:public Derived012345{};    //6 class DerivedMultiple : BaseA, Derived012345{};  //6 class DerivedMultiple2: Derived012345, BaseA{}; //6

解决方案

避免类具有深的继承层次结构。
