具有更多参数的模板(Template with more parameters)

 我正在尝试进行多用途调试功能。 这有效，但现在我想添加两件事： 
 
 
 
 使其具有可变数量的不同参数。 
 
 
 添加变量名称的输出，例如：a：42 b [0]：54 
 
  
 
   
template<bool B> struct Print {};

template<> struct Print<true> {
template<class T> static int do_it (T a)  { cout << a << endl; }
};  

template<> struct Print<false> {
  template<class T> static int do_it (T & a) {
      for (int _n(((int)((a).size()))-1), i(0); i <= _n; i++)
          cout << *(next(a.begin(),i)) << endl;
              cout << endl; 
  }
};

template<class T>
int debug (T A){
       return Print<std::is_scalar<T>::value>::do_it( A ) ;
}

int main(){
  int a = 42;
  vector <int> b;
  b.push_back(54);
    debug(a); // Works
  debug(b); // Works
    debug(a,b); //It's what i'm trying to do.
  return 0;
}
 
  
 
 
 PS：c ++ 11 

I'm trying to do a multiuse debug function. This works but now i'd like to add 2 things:
 
 
 
Make it work with a variable number of different parameters.
 
 
Add the output of the name of the variable, as example: a: 42 b[0]: 54
 
  
 
   
template<bool B> struct Print {};

template<> struct Print<true> {
template<class T> static int do_it (T a)  { cout << a << endl; }
};  

template<> struct Print<false> {
  template<class T> static int do_it (T & a) {
      for (int _n(((int)((a).size()))-1), i(0); i <= _n; i++)
          cout << *(next(a.begin(),i)) << endl;
              cout << endl; 
  }
};

template<class T>
int debug (T A){
       return Print<std::is_scalar<T>::value>::do_it( A ) ;
}

int main(){
  int a = 42;
  vector <int> b;
  b.push_back(54);
    debug(a); // Works
  debug(b); // Works
    debug(a,b); //It's what i'm trying to do.
  return 0;
}
