C++ adapter design pattern

below is oonly for fixed source and target. Please looking forward to the all-powerfull converetor.

#include <string>
#include <iostream>


class Target{
public:
  virtual void target_request(){ std::cout << "Target request" << std::endl; };
};

class Source{
public:
  virtual void source_request(){ std::cout << "Source request " << std::endl; };
};

class Convertor:public Target, private Source{
public: 
  virtual void target_request(){  this->source_request(); };
};

int main(){
  Convertor* c = new Convertor();
  c->target_request();
  return 0;
}

// class Convertor:public Target{
// public: 
//   Target* target;
//   Convertor( Source *s): source(s){};
//   virtual void target_request(){ return source->source_request(); };

// private:
//   Source* source;
// };

// int main(){
//   Source* s = new Source();
//   Target* c = new Convertor(s);
//   c->target_request();

//   return 0;
// }
