一个简单的模板例子

#include <iostream>

using namespace std;

template <class T> class B {  public:   void show(T a); };

template <class T> void B<T>::show(T a) {  cout<<a<<endl; }

template <class T1,class T2> class A:public B<T2> { public:  void Test(T1 a,T2 b); };

template <class T1,class T2> void A<T1,T2>::Test(T1 a,T2 b) {  cout<<a<<endl;  show(b); }

int main() {  A<int,char *> *a=new A<int,char *>();  a->Test(100,"hello world");  delete a;

 return 0; }
