134. Private Inheritance

#include <iostream>
using namespace std;

class Device {
public:
  void showType() { cout << "Generic Device\n"; }
};

// your code here: define class Actuator with private inheritance from Device
// implement showActuator() that calls showType() and then prints "Actuator
// Device"
class Actuator : Device {
public:
  void showActuator() {
    showType();
    cout << "Actuator Device" << endl;
  }
};

int main() {
  Actuator a;
  a.showActuator(); // should print both lines
  return 0;
