How to pass a callback function as an argument (Arduino, C++)

Arduino Uno:

bool myCallback(int value) {
  // here your custom logic
  return status;
}

void myFunction(bool (*callback)(int)) {
  // here your custom logic
  bool status = callback(3);
}

void loop(void) {
  myFunction(&myCallback);
}

Using of the std C++ library:

bool myCallback(int value) {
  // here your custom logic
  return status;
}

void myFunction(std::function<bool (int)> callback) {
  // here your custom logic
  bool status = callback(3);
}

void loop(void) {
  myFunction(myCallback);
}

Fantastic. this saves my time.
