模板类的继承包括四种：
1.（普通类继承模板类）
[cpp] view plain copy template<class T> class TBase{ T data; …… }; class Derived:public TBase<int>{ …… };2.（模板类继承了普通类（非常常见））
[cpp] view plain copy class TBase{ …… }; template<class T> class TDerived:public TBase{ T data; …… };3.（类模板继承类模板）
[cpp] view plain copy template<class T> class TBase{ T data1; …… }; template<class T1,class T2> class TDerived:public TBase<T1>{ T2 data2; …… };4.（模板类继承类模板，即继承模板参数给出的基类）
[cpp] view plain copy #include<iostream> using namespace std; class BaseA{ public: BaseA(){cout<<"BaseA founed"<<endl;} }; class BaseB{ public: BaseB(){cout<<"BaseB founed"<<endl;} }; template<typename T, int rows> class BaseC{ private: T data; public: BaseC():data(rows){ cout<<"BaseC founed "<< data << endl;} }; template<class T> class Derived:public T{ public: Derived():T(){cout<<"Derived founed"<<endl;} }; void main() { Derived<BaseA> x;// BaseA作为基类 Derived<BaseB> y;// BaseB作为基类 Derived<BaseC<int, 3> > z; // BaseC<int,3>作为基类 }
