How to specialize only some members of a template class?

Question

Code:

struct A {
  void f1() {};

};

template<>
struct A {
  void f2() {};
};


int main() {
  A<         


        

Answer 1

Would this help:

template
struct A
{
  void f1()
  {
    // generic implementation of f1
  }
  void f2()
  {
    // generic implementation of f2
  }
};

template<>
void A::f2()                                                               
{
  // specific  implementation of f2
}
