Metaprogramming with std::is_same

Question

Is it possible to do something like the following that compiles without template specialization?

template  
class A {
public:
  #if std::is_same&l         


        

Answer 1

Yes, with template specialization :

template  
class A;

template <> 
class A
{
    void had_int(){}
};

template <> 
class A
{
    void had_char(){}
};
