C++ override/overload problem

Question

I\'m facing a problem in C++ :

#include 

class A
{
protected:
  void some_func(const unsigned int& param1)
  {
    std::cout << \"         


        

Answer 1

The problem is that in the derived class you are hiding the protected method in the base class. You can do a couple of things, either you fully qualify the protected method in the derived object or else you bring that method into scope with a using directive:

class B : public A
{
protected:
  using A::some_func; // bring A::some_func overloads into B
public:
  virtual ~B() {}
  virtual void some_func(const unsigned int& param1, const char*)
  {
    A::some_func(param1); // or fully qualify the call
  }
};
