¿Cómo agregar listas / señales de eventos a una clase de superman simple?

I can and would love to use boost or std for this. Sorry - I am new to C++. So I created a really simple program like:

#include <iostream>
#include <string>
using namespace std;

class superman
  void punch(){cout << "superman: I hit the bad guy!" << endl;};

int main()
  superman clark;

I want to add an event listner that would tell me when clark punched and cout something like "superman punched!". How to add such event listner and event function to my class?

cout << "superman: I hit the bad guy!" << endl; no devuelve un std::string . Which compiler are you using ? -

puedes usar boost::signal para que

you have to declare one class and overload her operator () after uoi have to bind the class on the signal, by using connect() method, and finally, use operator () of the signal

struct HelloWorld 
  void operator()() const 
    std::cout << "Hello, World!" << std::endl;

// ...

// Signal with no arguments and a void return value
boost::signal<void ()> sig;

// Connect a HelloWorld slot
HelloWorld hello;

// Call all of the slots

for using parameter in slot:

void print_sum(float x, float y)
  std::cout << "The sum is " << x+y << std::endl;

boost::signal<void (float, float)> sig;


sig(5, 3);
