使用模板实现编译期间多态（类名当参数）

#include <iostream>
using namespace std;

class DemoOne{
public:
  void f(bool someParm=true){ cout<<"DemoOne f functions\n";}
  void g(){ cout<<"DemoOne g functions\n";}
  // other functions...
};


class DemoTwo{
public:
  void f(){ cout<<"DemoTwo f functions\n";}
  void g(double a=1.12,double b=1.123){ cout<<"DemoTwo g functions\n";}
  // other functions...
};

template<typename T>
void h(T& t){
  t.f();
  t.g();
}

int _tmain(int argc, _TCHAR* argv[])
{
  DemoOne one;
  DemoTwo two;
  h(one);
  h(two);

  return 0;
}
