Write your question here.

  class Menu {

  public:
  void welcome() {
       std::cout << "HELLO " << name << std::endl; //name of hero printed
     }
  }
  class Hero {
  private:
   std::string name;
   Menu menu;

  public:
  void getName() {
   return name; 
  }
  void welcomeFromHero() {
       menu.welcome() // i know i can pass here name to function but there are multiple values, can i pass the whole hero object?
     }
  }

Yes. Using the this pointer. this is the pointer to the object it’self.

   class Menu {

  public:
  void welcome() {
       std::cout << "HELLO " << name << std::endl; //name of hero printed
     }
  }
  class Hero {
  private:
   std::string name;
   Menu menu;

  public:
  void getName() {
   return name; 
  }
  void welcomeFromHero() {
       menu.welcome(*this) // i know i can pass here name to function but there are multiple values, can i pass the whole hero object?
     }
  }

pass the least thing you need.
pass the string.

void welcome(string &s);
...
menu.welcome(name);
menu does not need the whole class in this scenario. If it needs all of it for something else, disregard.

Why would the Hero call menu.welcome to welcome himself ?
